Effect of environmental factors on the population dynamics of major sucking pests of okra (Abelmoschus esculentus L.)
(Malhotra Publishing House, 2020) Bhawani Singh Meena; S.V.S. Raju; S. Ramesh Babu; Kamal Ravi Sharma
Incidence of jassids was started during 34th SW, while initial aphids and whitefly infestation was observed during 35th SW. However, peak population of aphids had been observed during 41st SW, whereas, whiteflies and jassids population has reached its peak level on 40th SW. The correlation analysis showed that the aphid population has significantly positive correlation with morning RH, evening RH, average RH and maximum temperature and positive non-significant correlation with average temperature. Further, negative non-significant correlation showed with minimum temperature, while rainfall showed significant negative correlation with aphid population. Correlation analysis of certain abiotic factors with Jassid and whitefly revealed that the population also showed positive correlation with temperature and relative humidity. However, the pests population showed negative correlation with rainfall. © J. ent. Res.
EFFICACY OF INSECTICIDES AGAINST SHOOT AND FRUIT BORER EARIAS VITELLA IN OKRA
(The Entomological Society of India, 2025) Bhawani Singh Meena; Shakuntala; Samantapudi Venkata Satyanarayana Raju; Pooja Sharma
The efficacy of ten insecticides against the shoot and fruit borer Erias vitella on okra was assessed in the field at Research Farm, IAS, BHU, Varanasi during kharif, 2018. Indoxacarb 14.5% SC @ 72.5 g a.i. ha-1 led to the lowest infestation of shoot (6.30 and 5.37%) and fruit (3.25 and 3.73%) after first and second spray. Highest reduction (61.22 and 74.81%) was significantly observed in the plants treated with indoxacarb 14.5% SC @ 72.5 g a.i. ha-1 followed by indoxacarb 14.5% +acetamiprid 7.7% SC @72.5+38.5 g a.i. ha-1 (51.36 and 69.09%). Indoxacarb 14.5% SC @ 72.5 g a.i ha-1 and indoxacarb14.5% + acetamiprid 7.7% SC @ 72.5+38.5 g a.i. ha-1 treated plots were the best and gave highest yield. © 2025, The Entomological Society of India.
