season, 2019. A category of insect was recorded on four sucking and six solid feeder insect. The population of Jassid, cowbug and leaf webber were recorded from 32nd SW to 50th SW where population rang was 0.33±0.58-6.67±2.31, 0.67±0.19-3.00±0.33 and 1.33±0.58-9.33±0.58 insect/week, respectively. The maximum population of pod bug (10.67±1.53 bug/plant/week), green bug (5.00±1.0053 bug/plant/week), spotted pod borer (8.67±0.58 larvae/plant/week), blister beetle (2.67±1.15 adults/plant/week), pod fly (5.00±1.00 larvae/plant/week), pod borer (8.33±0.58 larvae/plant/week) and plum moth (4.33±0.58 larvae/plant/week) were recorded from 10th, 44th, 48th, 44th, 45th, 49th and 49th SW, respectively.

Impact of integrated Pest management (IPM) for cacao pod borer attack (Conopomorpha cramella (Sn.)) (Lepidoptera: Gracillariidae) dan Helopeltis sp.(Hemiptera : Miridae). Research on impact of integrated Pest management (IPM) for cacao pod borer attack (Conopomorpha cramella (Sn.)) and Helopeltis sp. had been conducted at Tumbik Melayu Village, Teluk bayur District, Berau Regency, in East Kalimantan, starting from May to September 2002. It used nested classification design. IPM practices applied in this research were pruning, balanced fertilization, weeding, field sanitation (leaf mulch), light pruning, fregment harvesting (every week), burrying of pod shell, and wrapping of young pod in week 15th. Result of the research revealed that IPM application could reduce the cacao pod borer attack reaching: a) light category before treatments from 41.29 to 15.00%; b) heavy category before treatments from 20.56 to 0 and 23.37%, compare to farmer plot. IPM implementation were able to increase percentage of healthy pod up to 18.66% compared to farmer plot. Beside it could suppers development of Helopeltis sp. population up to 24%. The dominant natural enemies were spider as many as 1.34 individuals per plant on IPM plot and 0.6 spider per plant on farmer plot (non IPM). Application of IPM practices were able to increase agronomic character: a) number of flower up to 37.22% when compare to farmer plot, and b) number of fruits until 5.56%, whereas number of young fruits decrease up 13.25%.

Experiments on validation of integrated pest management (IPM) module against insect pest of pigeonpea in comparison with the Non-IPM (farmer’s practices) were conducted at N.E.B. Crop Research Centre, G. B. Pant University of Agriculture & Technology, Pantnagar during Kharif 2014 and 2015. Adopted IPM module contained Seed treatment with Trichoderma spp. @10g/kg of seed, Sole crop, Bird perches @ 50/ha, need based insecticides spray (Chlorantraniliprole 18.5SC @ 30 g a. i./ha; Neem soap@10g/lit; Acetamiprid 20SP @ 20 g a. i./ha). The results indicated that minimum population of pod borers (Helicoverpa armigera,Maruca vitrata and podfly) and sucking insects (aphids, jassids, pod bug) was reported in IPM plots and maximum population of insects was observed in Non-IPM plots. Percent insect control over non-IPM was 50.98 % for H. armigera, 44.69 % for M. vitrata and 19.17 % for Maruca webbing were recorded. While, for sucking pest complex, insect control over non-IPM was 51.59 %, 40.36 % and 36.17 % against jassids, aphids and tur pod bug, respectively. Similarly, minimum pod borer damage (6.48 and 7.71 %) was recorded in IPM plots as compared to maximum pod borer damage (8.37 and 8.22 %) in non-IPM plots, respectively during 2014 and 2015. Whereas, pooled grain yield for IPM plots was 1286.5 kg/ha for both seasons as against 888 kg/ha in non-IPM plots with 1:2.89 benefit cost ratio. Hence, It is apparent that studied IPM module was able to increase the yield of pigeonepea with lower cost of production as against non-IPM thus it would be benefiting the farmers.

AbstractPigeon pea (Cajanus cajan) is an important pulse crop in the Indian diet and one of the most important sources of dietary protein for the population. In the context of the fourth phase of the Indo-Swiss Collaboration in Biotechnology, an assessment how farmers and consumers perceive new pigeon pea cultivars and what are their preferred traits was conducted. This investigation assessed India’s food security implications due to stagnating and low yield of pigeon pea and ascertain farmers’ preferences of pigeon pea varietal traits, production constraints and farmers’ coping strategies in diverse pigeon pea production environments. Results indicated that production constraints in the studied regions were basically similar, with majority of the farmers identifying pod borer & pod fly as the major pest, and wilt as the major disease and drought as a major production constraint. Farmers indicated the use of clean seed, high yielding varieties, inter & mixed cropping, planting density, and manure application as some of the strategies they used to cope with the production constraints. In terms of preference for new cultivars, farmers want high grain yield with drought tolerance, medium to early maturity, pod borer resistance, tolerance to wilt disease, moderate plant height and ease of threshing without compromising other preferred attributes. The analysis of processors’ preference of grain types for dal processing showed that uniform size, oval shape, orange coloured seed and most importantly moderately hard seed coat are highly desirable. Consumers lacked awareness on the varieties, but considered traits like uniform seeds and reduced cooking time traits more desirable.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
