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

An in situ survey on native natural enemies of okra shoot and fruit borer, Earias vittella was conducted during September-October 2008, at IIVR research farm, Varanasi, Uttar Pradesh, India. The survey revealed that Trichogramma chilotraeae Nagaraja and Nagarkatti is a potential egg parasitoid which was occurring naturally in the okra ecosystem in spite of the pubescence of the okra plant. This is the first record of natural parasitism of T. chilotraeae on E. vittella.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

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.

Yellow mite is a serious pest of many field and horticultural crops including jute. As repeated use of acaricides possess problem of resistance, alternatively, the infectivity of talc based formulation of three entomopathogens, i.e., Lecanicillium lecanii (Ll), Isaria fumosorosea (=Paecilomyces fumosoroseus) (Pf) and Beauveria bassiana (Bb) at 4 × 108 cfu/ml, and 6 × 108 cfu/ml concentrations were evaluated against yellow mite under laboratory condition. In both the concentrations, Pf and Bb recorded significantly higher mortality of yellow mite than Ll. At 3-DPT (days post treatment) significantly highest mortality was observed in Pf (30.35%) followed by Bb (21.59%) and Ll (4.87%). Later on at 4 and 5-DPT period the level of mortality in Pf and Bb treated population was at par but significantly higher than Ll. At 5-DPT, Pf recorded maximum cumulative mortality (40.92%) at par with Bb (35.99%) and significantly higher than Ll (12.92%). Significantly higher cumulative mortality at 6x108 CFU/l concentration during 5 days after treatment was 34.35%. The infectivity of talc based formulation of Ll at both the concentrations was significantly less than Pf and Bb. Higher infectivity of I. fumosorosea indicates it to be ideal for yellow mite control in jute.Keywords

survey for weed killers in jute-based crop ecosystem was conducted at the research farm of ICAR-CRIJAF, Barrackpore during 2018 and 2019 cropping season. The nutgrass weevil, Athesapeuta cyperi caused 46.67 – 85.00% dead heart in Cyperus rotundus in the jute ecosystem. This is the first report of A. cyperi on nutgrass in the jute ecosystem in West Bengal. This study throws a hope of using this weevil as a potential biocontrol agent against the most notorious weed the nut grass, which has been gradually developing resistance against many of the commonly used herbicides.
