“…The parasitoid, P. obliquae is a gregarious, endoparasitoid specific to S. obliquae and parasitize to the extent of 38% up to third instar of larvae. Rahman and Khan (2010) also found that the larval parasitoid, Apanteles oblique (Braconidae: Hymenoptera) was found attacking the larvae of S. obliqua.…”

“…Information on spectrum and type of native natural enemies is a pre-requisite for large scale inundative release of biocontrol agents. The jute agro-ecosystem supports large number of natural enemies (Rahman et al, 2009) and their importance in integrated approach for management of pests of jute has been developed (Rahman et al, 2010). The role of natural enemies for management of S. obliqua needs to be explored.…”

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.

“…As jute farmers in Raiganj had chances for proper training by the Krishi Prajukti Sahayak (KPS) knowledge of them are more consistent. Different authors (Khan, 1956;Maheswariah et al, 1956;Rahman and Khan, 2010) advocated that Knowledge about insect pest is benchmark for the development of Integrated Pest Management.…”

Farmers’ knowledge, perceptions and practices in jute insect pest management and cultural strategy in the upper Gangetic plains of West Bengal, India

A survey on jute farmers' knowledge, perceptions and practices (KPP) in pest management strategy was conducted during jute cultivation season of 2015 in the upper Gangetic plains of Uttar Dinajpur District, West Bengal, India. Detection and control of insect pests was largely based on damage symptoms of host plant. Damage caused by jute semilooper (Anomis sabulifera) was often mistakenly attributed to other leaf feeding caterpillars. Nearly all of the farmers applied insecticides (99%) without target specific use with an average 1.5 per season which may increase up to two to three spray per week. Pyrethroids were mostly accepted insecticide (67%), followed by organophosphates (33%) without knowing its toxic effect on environment. Farmers' estimated yield loss due to insect pests was significantly correlated to estimated pest control cost. Due to pesticide sellers' recommendations, farmer's insecticidal 'spray load' significantly increased in every year, whereas the adopted number of insecticidal increased with advice following the guidance of extension staff and advertisement. Expenditure for pesticides was in concurrent with that of fertilizers. Only 10% of participating farmers knew about natural enemies, all of which were predators. Investigation is needed to evaluate whether significant savings can be obtained given a more judicious use of pesticides.

“…The avoidable losses in fibre yield due to multiple infestations by the pests were found to be 31-34% (Rahman and Khan 2006) in West Bengal. The jute agroecosystem supports large number of natural enemies of crop pests (Rahman and Khan 2009) and considering their importance, an integrated approach for management of pests of jute have been developed (Rahman and Khan 2010). Generally, the pests of jute usually appear at different stages of crop and some varieties are more prone to attack than others.…”

This study was conducted with a view to understand the effect of plant characteristics on the incidence of pests on most popular jute varieties, viz. JRO-524, JRO-632, JRO-878, JRO-7835 of olitorius jute and JRC-212, JRC-321, JRC-4444, JRC-7447 of capsularis jute. Correlation studies of plant characteristics with pest incidence in jute (Corchorus spp.) revealed that the basal girth of plant exhibited a positive significant relationship with the incidence of Apion corchori Marshall but not with other pests such as jute semilooper (Anomis sabulifera Guen.), Bihar hairy caterpillar (Spilarctia obliqua Wlk.), grey weevil (Myllocerus discolor Bohemus) and yellow mite (Polyphagotarsonemus latus Banks). However, plant height showed positive correlation with the incidence of all the major pests of jute. Leaf characteristics (number of leaves/plant, leaf area, leaf thickness, moisture and chlorophyll content of leaves of all the varieties recorded at three different growth stages, i.e. at 50, 80 and 110 days after sowing), number of leaves/plant had positive and significant relationship with the incidence of all the pests except stem weevil. However, leaf area and moisture content of leaves showed significant positive relationship with the incidence of yellow mite. Leaf moisture also showed a positive role on the infestation of grey weevil. Leaf thickness and chlorophyll content of leaves and stem, fibre thickness and moisture content of stem did show any significant effect on pest's incidence. Upon comparing the plant characteristics between the two jute species, olitorius varieties had greater fibre thickness than that of capsularis varieties but fibre thickness had no significant impact on incidence of pests.
