The field efficacy of Beauveria bassiana in comparison with the commercial formulation of B. bassiana (Daman) and standard check malathion 50 EC against Hydaphis coriandri and Aphis craccivora showed significant variations among pre-treatment and post-treatment counts. H coriandri, one day after treatment (DAT) a significant reduction (70.22%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (15.22%). At 7 DAT, the highest population reduction was 92.81% in malathion 50 EC followed by Daman (83.41%) was recorded, whereas in A.craccivora one-DAT, a significant reduction (68.42%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (10.70%). At 7 DAT, the highest population reduction was 90.0% in malathion 50 EC followed by Daman 81.34% were observed. Daman showed significantly high percent of reduction (54.60%) and (47.35%) in H coriandri and A.craccivora, respectively. However, the standard check, malathion 50 EC were highly toxic and showed significantly high percentage reduction (84.85%) and (82.55%) in the both the aphids population.Keywords

Laboratory bioassays were carried with seven different concentrations of Beauveria bassiana against Hyadaphis coriandri by using detached leaf bioassay technique with slight modifications. The mortality in treated aphids increased in conidial spore concentration. The highest concentration (1x1010 conidia ml-1) caused maximum cumulative mortality (96.85%) at 7 days after treatment compared to the lowest concentration (1×104 conidia ml-1) with 67.61 per cent mortality. The median lethal concentration (LC50) value recorded with B. bassiana was 1.5x104 conidia ml-1 in mixed H. coriandri population. Median lethal time (LT50) values were found to be inversely proportional to the spore concentration of B. bassiana and were observed as 45.70, 67.60, 71.30, 87.04, 97.72, 120.26 and 141.57 h for 1010, 109, 108, 107, 106, 105, 104 conidia ml-1, respectively.Keywords

A survey on native natural enemies of jute hairy caterpillar, Spilosoma obliqua Walker was conducted during April- July 2012 at CRIJAF, Barrackpore, Kolkata, West Bengal, India. The survey revealed that Meteorus spilosomae Narendran& Rema is a potential larval parasitoid which was occurring naturally in the jute ecosystem. This report confirms the parasitization of S. obliqua larvae by M. spilosomae in jute ecosystem of West Bengal for the first time.Keywords

A survey on native natural enemies of Bihar hairy caterpillar, Spilosoma obliqua Walker was conducted during April- August 2012 cropping season at ICAR-CRIJAF, Barrackpore as well as jute growing belts in West Bengal, India. The survey revealed that Protapanteles obliquae (Wilkinson) (Braconidae: Hymenoptera) is a potential larval parasitoid of S. obliqua which is occurring naturally on jute. This is the first record of natural parasitism of P. obliquae on S. obliqua on jute crop in India.Keywords

A invasive rugose spiraling whitefly (RSW) Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) was found infesting coconut, banana, custard apple and several ornamental plants in Tamil Nadu, Andhra Pradesh and Kerala for the first time in India. The identity of the pest species was determined through morphological and molecular tools. Furthermore cytochrome c oxidase-I gene (658 bp) of RSW was sequenced (GenBank accession number KY209909) which would serve as an ideal molecular diagnostic marker for its identification irrespective of its phenotypic plasticity. During the survey, several natural enemies were recorded and maximum parasitism was recorded by Encarsia guadeloupae Viggiani (Hymenoptera: Aphelinidae) and its COI gene was sequenced and deposited as Encarsia sp. (GenBank accession number KY223606). Per cent parasitism ranged from 20.0 to 60.0 % in different collection locations, highest parasitism being recorded in Kerala as compared to other states. The predators recorded were Mallada sp., few coccinellids and predatory mites. This communication is the first report of the rugose spiraling whitefly, its host plant range and associated natural enemies in India.Keywords

Occurrence of the invasive rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin was found on coconut, banana, mango, guava, sapota, Indian almond, water apple, ball tree, rubber fig, butterfly palm, and ruffled fan palm for the first time in Karnataka. Severe damage was noticed in the coastal areas of Mangalore and Udupi and the infestation ranged from 20-35% in coconut and 24-38% in banana. Morphology and molecular based taxonomic tools were used to identity the pest and its natural enemies. Survey also revealed natural parasitism by the parasitoids Encarsia guadeloupae Viggiani and E. dispersa Polaszek (Hymenoptera: Aphelinidae) with 5-15% in coconut, 7-18% in banana and 22-30% in sapota. Besides, other commonly found natural enemies viz., Stethorus sp. associated with mites and Dichochrysa astur were also recorded. Furthermore, augmentation and conservation strategies for these parasitoids for the management of this invasive pest were discussed.Keywords

First ever record of family Xenasteiidae (Diptera: Brachycera: Cyclorrhapha) from mainland India is provided. Most of the previous records of this family are from coastal sites, as they have usually been found on islands in the Indian and Pacific Oceans. For the first time biology and life stages of Xenasteia are illustrated. Xenasteia members were found associated with an exotic rugose spiraling whitefly (RSW) colony of Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) in the coastal areas of Karnataka in southern India, however no direct obligate association could be diagnosed. Also for the first time Anagyrus sp. (Hymenoptera: Encyrtidae) was recorded from the genus Xenasteia as its solitary parasitoid. Worldwide, this is the first ever report of parasitism associated with any member of this little-known family Xenasteiidae.Keywords

Surveys were conducted in intensive jute growing areas of West Bengal to collect information on natural enemies and other entomopathogens infecting jute hairy caterpillar Spilosoma obliqua (Lepidoptera: Arctiidae). The jute crop supports large number natural enemies of S. obliqua and entomopathogens. Among the braconid larval parasitoids, Meteorus spilosomae (Hymenoptera: Braconidae) and Protapantales obliquae (Hymenoptera: Braconidae) were the key mortality factors. The activity of these parasitoids was noticed from mid- May to mid-July during the cropping season. The parasitoid, P. obliquae is a gregarious, endoparasitoid specific to S. obliqua and parasitize to the extent of 38% up to third instar of larvae whereas M. spilosomae reported to cause up to 77% of parasitisation on S. obliqua under field condition. Bacillus thuringiensis and nuclear polyhedrosis virus were found be very effective with mortality of, 64 and 93% respectively. These parasitoids and pathogens can be used as potential bio-control agents against jute hairy caterpillar through conservation, augmentation and mass multiplication.

The efficacy of different biocontrol agents, botanicals and a biorational insecticide were evaluated against whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae) in tomato under field conditions at Shivamogga, Karnataka during two seasons (Rabi 2018-2019 and summer 2019-2020). The results revealed that spiromesifen 240 SC @ 0.7 ml/L was the most effective in reducing the B. tabaci population i.e., 85.12 and 85.16 % reduction over untreated control during Rabi and summer, respectively followed by azadirachtin 5% @ 2 ml/l with reduction of 68.61 and 66.32 % over untreated control during Rabi and summer, respectively. The response of these treatments was also observed on the yield attributes, with highest fruit yield of 53.67 t/ha (6 pickings) in spiromesifen treatment followed by azadirachtin (52.93 t/ha), but the highest Benifit: Cost ratio was noticed in azadirachtin 5% (1:3.41), followed by spiromesifen 240 SC (1:3.38).Keywords
