Abstract

The green shield scale, Pulvinaria psidii Maskell, was found at high levels on red ginger (Alpinia purpurata K. Schum.) at IIHR Farm, Bangalore in June 2006. Following the release of the Australian ladybird beetle, Cryptolaemus montrouzieri Mulsant @10 / plant, the scale population declined from 174.60 scales / shoot on 15 June to 1.40 / shoot on 1 September in 2006. The population of C. montrouzieri ranged from 3.40 to 10.34 per shoot during the study period. Since no other natural enemies were recorded, the reduction in the population of P. psidii in the red ginger biocontrol plot was attributed mainly to the action of C. montrouzieri.

Abstract

Two hyperparasitoids, Prochiloneurus aegyptiacus (Mercet) and P. testaceus (Agarwal), were recorded for the first time on Anagyrus dactylopii (Howard), a primary parasitoid of pink mealybug, Maconellicoccus hirsutus (Green) infesting grapes at Bangalore, India. Hyperparasitism to the tune of 11% exerted by them could be detrimental to the primary parasitoid in countering the rate of increase of M. hirutus in vineyards.

Abstract

A field study was carried out to determine the efficacy of the Australian ladybird beetle, Cryptolaemus montrouzieri Mulsant, in the suppression of three mealybug species, namely, citrus mealybug, Planococcus citri (Risso), striped mealybug, Ferrisia virgata (Cockerell), and the spherical mealybug, Nipaecoccus viridis (Newstead), on pummelo (Citrus grandis Swingle). C. montrouzieri was released @ 30 larvae/plant in August 2005 in the pummelo orchard. The population of P. citri declined from 313.84/plant in August 2005 to 2.63/plant in October 2005, that of F. virgata from 248.85 to 7.57/plant and N. viridis from 165.48 to 6.85/plant in the same period. In the present investigation, a mean of 97.74%, 90.17% and 82.37% reduction in the population of P. citri, F. virgata and N. viridis, respectively, was recorded 60 days after Cryptolaemus release on pummelo.

Abstract

The pink hibiscus mealybug Maconellicoccus hirsutus (Green) appeared on sapota (Manilkara zapota Forbcrg) in April 2003 at the Indian Institute of Horticultural Research Farm, Bangalore. The Australian ladybird beetle Cryptolaemus montrouzieri Mulsant was released @20/plant on sapota plants infested with mealybugs. The mealybug population declined from 54.20/plant on April 23, 2003 to 1.50/plant on June 15, 2003. No other natural enemy except C. montrouzieri was observed on M. hirsutns in the present study. There was no significant influence of weather factors, namely, maximum and temperature, morning and evening relative humidity and rainfall, on the mealybug population. The decline in the mealybug population on sapota was attributed to the predatory activity of C. montrouzieri.

Abstract

The citrus mealybug, Planococcus citri (Risso) (Homoptera: Pseudococcidae) was observed infesting Crossandra undulifolia Salisb. in 2006 at the Indian Institute of Horticultural Research Farm, Bangalore. It is a new host plant for the pest in India and elsewhere. Since the application of conventional insecticides fails to control the mealy bugs, possibilities of its biological control were explored on crossandra. A total of 500 larvae of the Australian ladybird beetle, Cryptolaemus montrouzieri Mulsant were released in an area of 100 sq. metre planted with crossandra. Following the release of C. montrouzieri, the plants were almost cleared of the mealybugs after 3 months. Since the weather parameters such as maximum and minimum temperatures, relative humidity and rainfall did not show any significant relationship with the citrus mealybug population on crossandra, the decline in the mealybug population was attributed to the activity of the biotic agents, chiefly C. montrouzieri.

Abstract

The citrus mealybug, Planococcus citri (Risso) was found in large numbers infesting custard apple at Indian Institute of Horticultural Research Farm, Bangalore during August-October 2004. Sampling of infested custard apple fruits during this period revealed the presence of Leptomastix dactylopii Howard. Adult parasitoids were recovered after five years of its release in 1983 and again in 2004 in the present study indicating the permanent establishment. In general, the activity of parasitoids particularly on mealybugs on custard apple was very low. The natural parasitisation by L. dactylopii ranged from 0.41 to 2.72 percent but the presence of L. dactylopii indicated that there is some scope of exploiting L. dactylopii in the suppression of P. citri infesting custard apple.

Abstract

The mealybug Rastrococcus invadens Williams was recorded in serious form on sapota (Manilkara zapota Forberg) in May 2002 at the Indian Institute of Horticultural Research Farm, Bangalore. The coccinellid predator, CryptoiaemllS montrollzieri Mulsant was released for its suppression on sapota. The population of the mealybug declined from initial infestation of 507.61 shoot to 0.00 in two months time. No other natural enemy except C. montrollzieri was observed on R. invadens. The maximum temperature, minimum temperature, morning relative humidity and evening relative humidity ranged from 27 to 36 °C, 18 to 22 °C, 52 to 91 per cent and 30 to 76per cent, respectively. There was no marked influence of these abiotic factors on the mealybug population during the study period. The decline in the mealybug population on sapota was due to the predatory activity of C. montroltzieri.

Abstract

A severe infestation of the whitefly, Lipaleyrodes euphorbiae David and Subramaniam was observed in 1992 on star gooseberry (Phyllanthus acidus Linnaeus) at Indian Institute of Horticultural Research Farm, Bangalore. The whitefly infestation was higher during January to June than during July to December. Six natural enemies were found associated with the whitefly. Eretmocerus sp., Acletoxenus indicus Malloch, Triommata coccidivora (Felt), Mallada boninensis (Okamoto) and Cheilomenes sexmaculata (Fabricius) are reported for the first time on L. euphorbiae. However, only Eretmocerus sp. and A. indicus were collected in large numbers. No definite trend was observed in the whitefly infestation during 1992-94. Morning relative humidity (%) alone had a negative correlation with the whitefly infestation. The activity of Eretmocerus sp. was observed only from January to March, 93 and the predator A. indicus was found feeding on the whitefly nymphs during December, 92; and April and September-November 1993.

Abstract

The green peach aphid Myzus persicae (Sulz.) has become a major pest of chillies and sweet pepper (Capsicum annuum L.) in India. It is becoming increasingly difficult to control the aphid with insecticides. The investigations on the impact of the natural enemies revealed that the parasitoid Aphidius sp. appeared in large numbers causing upto 93.65% parasitism on M.persicae infesting chillies. In sweet pepper fields, both Aphelinus sp. and Aphidius sp. were recorded on M. persicae but the aphelinid was more abundant than the aphidiid. The rate of parasitism by Aphelillus sp. alone went upto 96.80% in April '92 in sweet pepper fields. The aphid population was effectively suppressed on chillies and sweet pepper by the parasitoids.

Abstract

Five insecticides and ten fungicides at the recommended field dosages were evaluated for their safety to the encyrtid parasitoid Anagyrus dactylopii (How.) and the coccinellid predator Cryptolaemus montrouzieri Muls. of Maconellicoccus hirsutus (Green). Quinalphos (0.05%), endosulfan (0.07%), malathion (0.1%), carbaryl (0.1%) and fenthion (0.1%) proved highly toxic to both the species. Fungicides except fosetyl-Al, dinobuton and dinocap were found harmless. Carbaryl had significantly high toxic residual activity upto 28 days after treatment against both the biocontrol agents. Fungicides, fosetyl-Al (0.2%) dinobuton (0.1%) and dinocap (0.1%) which int1icted 16-40 % mortality of Crypto1aemus adults on the day of application became non-toxic one day after treatment. Toxic residual activity of endosulfan and fenthion against A. dactylopii and C. montrouzieri decreased significantly in 7 days.

Abstract

Chrysopids play a major role in regulating the mealybug populations in nature. The green lacewing Mallada boninensis (Okamoto) is known to feed on many mealybug species (Boussienguet, 1986; Krishnamoorthy and Mani, 1989; Mani and Krishnamoorthy, 1989). The striped mealybug Ferrisia virgata (Ck11.), citrus mealybug Planococcus citri (Risso) and the common coffee mealybug, P. lilacinus (Ckl1.) pose variety of problems especially in fruit crops in India. According to Doutt (1951), the mealybugs could be controlled by large scale releases of chrysopids. With a hope to utilise M. boninensis against these mealybugs, its predatory potential was determined in the present study.

Leptomastix dactylopii (How.)(Hym., Encyrtidae) in citrus orchards against P. citri in and around Bangalore have resulted in establishment of the parasitoid and complete control of mealybugs within four months in 1984-85 (Krishnamoorthy and Singh, 1987). Subsequently a survey was conducted by making field recoveries to evaluate the dispersal and establishment of the parasitoid in other areas on different crops, where releases were not effected.

Abstract

The plant lice, Aphis gossypii Glov., is a polyphagous species widely distributed on a large number of crops in India (Ullah. 1940). On guava, colonies of nymphs and adults infest tender shoots and leaves, and suck the cell sap. They secrete honeydew resulting in development of sooty mould on leaves and shoots (Butani, 1974). On several occasions, insecticidal applications have increased the aphid population, and some times resulted in outbreaks (Hambleton, 1939; Orlandao et al., 1970). On the other hand, natural enemies themselves if uninterrupted by insecticides help to check the aphid popUlations. As many as 20 natural enemies were reported on A. gossypii in India. The present investigation was undertaken to deteffiljne the effectiveness of natural enemies in the suppression of A. gossypii in guava orchards.

Abstract

Allotropa japonica sp. n. a Platygasterld parasitoid of Maconellicoccus hirsutus (Green) completed its life cycle in 25.5 days at 25.5°C. It oviposited on all three nymphal stages and on the adult female mealybugs. The second and third nymphal stages (10-15 days old) were found suitable to breed the parasitold since tbe number of parasitoids emerging was greater, and ratio of female to male was also higher in these nymphal instars. Adult parasitolds were highly susceptible to monoaotophos, dichlorvos, dimethoate, oxydemeton methyl, methyl parathion, dlazlnon, chlorpyripbos, phosalone, qulnalphos, fenthion and carbaryl. But the acaricides and fungicides (dicofol, copper oxychloride, mancozeb, captafol, carbendazim, Bordeaux mixture) except sulphur proved less harmful to the parasitold.

Abstract

The effect of 2 different rates of release of an exotic predatory mite, Phytoseiulus persimillis of Athlas. Henriot on two-spotted spider mite, Tetranychus urticae Koch. on French beans was investigated. Release of predatory mite significantly reduced the population of spider mites in release plots compared to check. A release rate of 10 adults per plant gave better control than did 5 adults per plant. The mean fruit yield was also significantly higher in release plots than the check.

Abstract

Mealybugs, known to be 'hard to kill pests', live in protected areas and most stages in their life cycle are covered in a waxy coating. Several insecticides are found ineffective against mealybugs. Fortunately, mealybugs - being sessile insects - are more amenable to biological control. The exotic parasitoid, Leptomastix dactylopii How., was found to be highly effective in suppressing citrus mealybug, Planococcus citri (Risso.) permanantly on citrus, sapota, guava, pomegranate and coffee. This is one of the recent successes in classical biological control attempts in India. However, the Australian ladybird beetle, Cryptolaemus montrouzieri Muls., often provides spectacular control of heavy infestation of P. citri on acid lime, lemon, sweet orange, pummelo, Crossandra and custard apple. Though Anagyrus dactylopii (How.), is a potential parasitoid of pink hibiscus mealybug, Maconellicoccus hirsutus (Green), on grapes, releases of C. montrouzieri only help in suppression of the pink hibiscus mealybug on grapes, ber, guava, sapota, custard apple, citrus and hibiscus. The encyrtid parasitoid, Tetracnemoidea indica (Ayyar), was able to check the oriental mealybug, Planococcus lilacinus (Ckll.) on acid lime and pomegranate. The predators, C. montrouzieri and Spalgis epeus Westwood, also play a major role in suppression of P. lilacinus on guava, ber, sapota and chow-chow. The local parasitoid, A. dactylopii was seen to play a major role in suppression of spherical mealybug, Nipaecoccus viridis (Maskell) on citrus and jackfruit. Nevertheless, releases of C. montrouzieri are found highly effective in controlling N. viridis on acid lime and pummelo. Similarly release of C. montrouzieri is found to be highly effective in controlling striped mealybug, Ferrisia virgata (Ckll.), on guava, tuberose and Acalypha in 30-40 days of release. A local parasitoid, Aenasius advena Comp., also plays a major role in suppression of F. virgata on guava, mango, guava, hibiscus, fig, citrus, etc. Release of the coccinellid predator, C. montrouzieri, was found very effective in controlling the mango coccid, Rastrococcus iceryoides (Green) on mango and also on the medicinal plant Decalepis hamiltonii. The encyrtid, Praleurocerus viridis (Agarwal), was found very effective in reducing populations of R. iceryoides on guava. Spalgis epeus was found to be the predominant predator of the papaya mealybug, Paracoccus marginatus Williams and de Granara Willink, but releases of the exotic parasitoid, Acerophagus papayae (Noyes&Schauff), only provide excellent control of P. marginatus within 3-4 months of release. The second successful classical biological control attempt on mealybugs in India. The brinjal mealybug, Coccidohystrix insolita (Green), is known to attack brinjal, Coleus, Hibiscus, etc. Cryptolaemus montrouzieri effectively controlled mealybugs on these three crops in 30-40 days of release. Verticillium lecanii Zimm. (Phule bugicide @ 2g/L) is found to be effective in killing the mealybug. Other fungal pathogens, viz., Beauveria bassiana (Bals.) Vuill and Metarhizium anisopliae (Metch.), are also seen to infect mealybugs in rainy season under humid conditions.

Abstract

Pesticide residue persistence pattern in three vegetable crops, viz., tomato, cabbage and cauliflower, cultivated following previously developed pesticide residue-free IPM packages, was compared with a crop cultivated under conventional or non - IPM conditions. It was observed that vegetables grown as per IPM practices were safer to consume at harvest compared to those grown as per conventional cultivation practices, with chemical control as the sole means of plant protection. Pesticide residues, if present, were mostly in trace amounts (< 0.01 ppm) in vegetables grown as per IPM practices, except the residues of methomyl and monocrotophos in cabbage, where slightly higher levels of pesticides were observed.

Abstract

An in vitro study was conducted to determine the interaction effect of ten pesticides tested at field recommended dose on conidial germination, vegetative growth and sporulation of Lecanicillium lecanii(ZIMM.) ZARE&GAMS. Compatibility of L. lecanii to different pesticides was found to be varied. Conidial germination was 99.3 and 85.7% in Pongamia oil and acephate, whereas, it was totally inhibited by the presence of chlorothalonil, iprodion + carbendazim, carbendazim and thiophanate methyl indicating that these pesticides were highly toxic. Dinocap recorded as moderately toxic while endosulfan, abamectin and ethion were least toxic based to the germination of conidia. So also Iprodion + carbendazim did not and carbendazim allow L. lecanii to put forth mycelium growth in their presence. Thiophanate methyl, Pongamia oil, acephate, endosulfan, ethion and chlorothalonil were observed to be innocuous pesticides registering growth of mycelium upto 2.33, 2.23, 2.23, 2.03, 2.03 and 2.00 cm dia., respectively, from 0.6 cm dia. held in the center of Petri plate on 14^th day after treatment. As far as sporulation is concerned, Pongamia oil alone recorded the maximum yield of 47.2x10⁶ conidia/ml followed by 18x10⁶ conidia/ml, in chlorothalonil as against 20x10⁶ conidia/ml in control, which means that the pongamia oil exhibited synergistic effect on L. lecanii, yielding more conidial spores. Thus, based on in vitro interaction study, pongamia oil alone was found to be safe to the entamopathogenic fungus L. lecanii in nature and iprodion + carbendazim and carbendazim were found to be highly toxic.

Abstract

An IPM module with safe pesticide residues on cabbage, with already proven treatments such as carbosulfan, dimethoate, cypermethrin + profenofos and mancozeb under chemical method of control; NSP, Bacillus thuringiensis and Trichogramma bactrae under non chemical method of control were revalidated individually and in combination. Six releases of parasitoid T. bactrae at weekly intervals starting from 12 days after transplanting or spray of NSP 4% at 10-15 days interval, 4 times, starting from 20 days after transplanting, foliar spray of dimethoate and mancozeb gave good control of aphids, leaf blight and black rot respectively. Based on the effectiveness of the treatment and pesticide residues below their permissible levels in cabbage at harvest, a module was developed and tested in the field. The IPM package thus developed was found to control the pests effectively and at the same time the residues on the crop were within the safe limits.

Abstract

The exotic spiralling whitefly, Aleurodicus dispersus Russell, was observed to infest several ornamentals including rose, hibiscus, poinsettia and acalypha in and around Bangalore. Efforts were made to colonize the aphelinid parasitoid, Encarsia guadeloupae Viggiani, during 2002 - 2003 on the above ornamentals infested with the spiralling whitefly. A total of five predators, namely, Axinoscymnus puttarudriahi Kapur and Munshi, Cryptolaemus montrouzieri Muls., Anegleis cardoni (Weise), Mallada astur (Banks) and Cybocephalus sp. were observed on the spiralling whitefly on these ornamentals during the study but their impact on the spiralling whitefly was negligible. Inoculative releases of E. guadeloupae were made on rose (156 adults), hibiscus (179 adults), poinsettia (124 adults) and acalypha (247 adults). Encarsia guadeloupae was recovered within a month after its release with 3.43-32.94% parasitism. A steady decline in the population of spiralling whitefly was observed on these ornamentals. Encarsia guadeloupae was found to be the only parasitoid encountered throughout the study and the total parasitism steadily increased up to 96.00% on rose, 86.40% on hibiscus, 90.40% on poinsettia and 39.86% on acalypha at six months from release. Parasitism by E. guadeloupae was significant and negatively correlated with the population of spiralling whitefly on all the four ornamentals.

Abstract

Severe infestation of green shield scale Chloropulvinaria psidii (Green) was observed during 2003-04 on the medicinal plants namely Withania somnifera, Madhuca longifolia, Mimusops elengi and Wrightia tinctoria. The Australian ladybird beetle Cryptolaemus montrouzieri Mulsant was released @ 20 larvae/plant. Following the release of C. montrouzieri , the scale population declined from 173.48 to 4.35/plant on W. somnifera, 30.49 to 1.20/plant on M. longifolia, 90.20 to 3.57/plant on M. elengi and 240.86 to 4.92/plant on W. tinctoria. There was 89.13 to 97.96% reduction in scale population 45-75 days after release of C. montrouzieri on the above medicinal plants. No other natural enemy, except C. montrouzieri, was recorded on C. psidii. There was no correlation between temperature, relative humidity or rainfall and scale population. Hence, the reduction in population of green shield scale was attributed mainly to the action of C. montrouzieri.
