Investigations on the natural epizootics of Cladosporium cladosporioides (Fresenius) de vries were carried out on Okra grown at Tamil Nadu Agricultural University, Coimbatore during 2010 and 2011. Observations on the incidence of mycosed mites were monitored continuously on okra at weekly interval during the study period. Occurrence of mycosis on Tetranychus urticae Koch due to C. cladsoporioides was high during third week of August 2010 (67.58%) followed by first week of August 2011 (47.24%), respectively. Fungal infection on mites had significant positive correlation with relative humidity and negative correlation with sunshine hours during the study period. An epizootic incidence of Cladosporium cladosporioides recorded on T. urticae is the first report from Coimbatore, Tamil Nadu.Keywords

Survey conducted for inventorying the natural enemies of Tetranychus urticae Koch revealed the occurrence of predatory insects viz., Stethorus pauperculus (Weise) (0.00 to 8.65 %), Oligota sp. (0.00 to 5.98 %), Scolothrips sp. (0.00 to 5.69 %) and predatory mite, Amblyseius longispinosus (Evans) (0.00 to 6.43 %) in okra growing areas of Coimbatore district. Investigations on the predatory potential of these predators against T. urticae under laboratory conditions showed that the adult female of S. pauperculus consumed significantly more number of 167.14 eggs / 63.71 nymphs / 61.42 adults of T. urticae per day per individual. The grubs of S. pauperculus were as voracious as the adults and the predation increased with the advancement of larval stages. Similarly, adult Scolothrips sp. and A. longispinosus were more efficient than the immatures in devouring the prey. However, in case of Oligota sp., the grub stage recorded the maximum consumption of prey mite by devouring 81.28 eggs / 45.71 nymphs / 15.14 adults of T. urticae per day per individual.Keywords

In recent years, increased interest has been shown towards biological control based management practices following the unsatisfactory results with the application of conventional insecticides. In Integrated Pest Management, selection of right plant protection methods coupled with right appliance is important to tackle the target pest in an effective manner. In this context, microplot and field trials were carried out to evaluate the efficacy of the oil based formulation of B. bassiana (Bb 112) against chilli thrips, Scirtothrips dorsalis Hood to identify an effective delivery method among different sprayers used (ASPEE Maruyama Engine sprayer, Avenger ULV sprayer, ASPEE Battery sprayer, ASPEE Knapsack hand sprayer, ASPEE Hitech hand sprayer and CDA sprayer). Microplot experiment on chilli thrips, S. dorsalis revealed that the oil based formulation of B. bassiana (Bb 112) was significantly superior to all other treatments and recorded the highest cumulative mean population reduction of 47.54 per cent. The cumulative mean per cent reduction in first (at Kumarapalayam) and second field trial (at Ambilikkai) against Chilli thrips showed that, oil based formulation of B. bassiana (Bb 112) @ 108 spores ml-1 sprayed with CDA sprayer was significantly superior to other treatments with 43.01 and 46.65 per cent reduction, respectively.Keywords

For insect diversity studies to be of value, the sampling methods employed must produce samples representative of the community or taxon selected for the investigation. However, as yet, few evaluations on the variability and effectiveness of sampling methods have been undertaken. The survey was carried out in the rice fields during 2015-16 in Paddy Breeding Station, Tamil Nadu Agricultural University, Coimbatore. From this study a total of 1,019 parasitoid individuals were collected. Among six different collection methods employed for sampling hymenopteran parasitoids in rice ecosystem, the yellow pan trap at ground level was found to be the most effective method in trapping the parasitoids (27.2 ± 2.56 parasitoids per day) followed by sweep net method (12.1 ± 1.03 parasitoids per day). The next best sampling method is yellow pan trap erected at canopy level which recorded a mean of 9.2 ± 2.26 parasitoids per day. The other three traps viz., malaise trap, suction trap and light trap were found to collect less number (<1.5) of parasitoids per day.Keywords

Biopesticides are promising alternatives to chemical pesticides, and they have opened up new panorama in insect pest management to aid in the promotion of safe, eco-friendly pest management. They are relatively host specific and do not interfere with other biotic systems. Research concerning the development of biopesticides has focused mainly on identification of virulent isolates of bioagents for effective management of the target pests. However, information pertaining to their effects on natural enemies, non-target pests, and environment is scanty. In the present study, oil formulation of fungal pathogen, Beauveria bassiana (Bb 112) was tested against adults of Cryptolaemus montrouzieri Mulsant (Coleoptera:Coccinellidae), under laboratory condition. Oil formulation of B. bassiana (Bb 112) has been found to be safer to C. montrouzieri adults with maximum adult survival of 92.62 per cent at the highest dose (108 spores ml-1) and 100 per cent survival at lower dose tested (104 spores ml-1) respectively.Keywords

Surveys were conducted to explore the Ichneumonid fauna in rice ecosystems of Tamil Nadu during 2015-16 in three different rice growing zones viz., western zone, Cauvery delta zone and high rainfall zone. Totally 604 Ichneumonid individuals were collected from rice ecosystem in the present study. These 604 individuals represent 14 subfamilies, 24 genera and 33 species. Alpha and beta diversity were computed for the three zones and the diversity indices (Simpson’s index, Shannon-Wiener index, Pielou’s index) revealed western zone as the most diverse zone, while Cauvery delta zone being the least diverse. Leptobatopsis indica was the dominant Ichneumonid species in the rice ecosystem with a relative abundance of 8.1%. On comparing the species similarities using the Jaccard’s index among the three zones taken in pairs, it was found that 12 per cent similarity between Western and Cauvery delta zones and no similarity between high rainfall and Cauvery delta zones and 25 per cent similarity between high rainfall and western zones.

Bioassay studies were performed with ten different fungal isolates of six species against two spotted spider mite, Tetranychus urticae. Among different formulations, Hirsutella thompsonii caused significantly higher mortalities of 61.1, 35.8 and 22.1 per cent at conidial concentrations of 971, 196 and 36 conidia mm-2, respectively. At a conidial concentration of 1457 conidia mm-2, Beauveria bassiana isolate Bb101 caused significantly higher mortality rate of 46.9 per cent followed by B. bassiana isolate B2 (36.1%) and Cladosporium cladosporioides isolate Cc101 (32.1%). Based on the probit estimates, H. thompsonii was found to exert high ovicidal activity with the lowest LC50 of 674 conidia mm2 against T. urticae eggs.
