Experiments were conducted to evaluate the efficacy of different biocontrol agents against shoot and fruit borer, Earias vittella (Fabricius) infesting okra at Biological Control farm, Anand Agricultural University, Anand (Gujarat) during two successive years, kharif, 2018 and 2019. Among the different biocontrol agents evaluated, the plots sprayed with Bacillus thuringiensis @ 5 g/litre for three times at fortnightly interval witnessed lowest larval population (0.52 larva(e)/plant) and fruit damage (7.00%-number basis, 8.09%-weight basis). The treatment comprising six releases of egg parasitoid Trichogramma chilonis @ 50,000 parasitoids/ha was found next effective treatment with lower larval population (0.67larva(e)/plant) and fruit damage (8.19%-number basis, 9.97%-weight basis). This bio-efficacy of egg parasitoid T. chilonis was statistically at par with the efficacy of treatments viz., Neem Seed Kernel Extract (NSKE) @ 5% and Beauveria bassiana@ 5 g/litre. The highest fruit yield was documented in the treatment B. thuringiensis @ 5 g/litre (111.02 q/ha, CB ratio 1:2.79) followed by the treatments T. chilonis @ 50,000 parasitoids/ha (105.10 q/ha, CB ratio 1:2.77) and NSKE @ 5% (104.64 q/ha, CB ratio 1:2.76). The significant findings of this study could be used to frame BIPM strategy for the management of shoot and fruit borer, E. vittella in okra.

Field surveys were conducted during kharif, 2019 and rabi, 2019-20 to document the fall armyworm (FAW) incidence and damage in maize fields of Anand district of Gujarat. The highest pest incidence and damage was recorded in maize fields of Khambhat taluka of Anand district during the study, while the lowest pest incidence and damage was recorded in Tarapur taluka. During kharif season, the highest pest incidence and damage was recorded in August month and during rabi season, the highest incidence of FAW and its damage in various maize fields was observed in November. It was noticed that the pest incidence was high in kharif season compared to rabi season. The significant differences were noticed with regard to FAW larval population and plant damage levels between the two seasons of the study. During the survey, the natural enemies of FAW viz., Chelonus sp., Coccinellids, Forficula sp., Eocanthecona sp., Cosmolestes sp., Spider (Oxyopes sp.) and Geocoris sp. were recorded. Similarly, Bacillus thuringiensis, Metarhizium (Nomuraea) rileyi and Nucleo Ployhedrosis Virus (NPV) infected FAW larvae were also noticed.Keywords
