Temperature Predicts the Population of Aceria cajani Chan. (Acari: Eriophyidae) and Efficacy of Insecticides and Acaricides in its Control on Pigeonpea [Cajanus cajan (L) Millsp.]

Background: The pigeonpea eriophyid mite, Aceria cajani Chan., vector of sterility mosaic disease in pigeonpea, causes economic damage up to 90% during the early stages crop growth. major element deploying management practice is know population dynamics pest. Generally, vectors causing agents were managed with synthetic chemical. So we have taken studies efficacy insecticides and acaricides its control on pigeonpea. Methods: A. Chan. was monitored field plots from January 2021 December 2021. For a completely randomized design organized. Twelve treatments (insecticides/acaricides) tested against [var. ICP 8863 (Shree Maruti]. Result: This study found that mite reached peak summer (March) another post-monsoon period (October), whereas lowest populations recorded winter (January). Correlation exhibited significant positive correlation both maximum minimum temperature. insecticide acaricide trials all chemicals used effective entomopathogenic formulations comparatively less effective.
