Insecticidal Activity of Essential Oils from Mint and Ajwain against Pulse Beetle <i>Callosobruchus chinensis</i> (L)

The present study evaluates the insecticidal activity of two essential Oil (EOs) mint (Mentha arvensis), and ajwain (Carum capyicum) against pulse beetle (Callosobruchus chinensis) (L). Contact toxicities these were evaluated using parameters lifecycle like total development period, numbers eggs laid, adult emergence longevity. Along with detoxification enzyme inhibition activities acetyl cholinesterase (AChE), alkaline phosphatase (ALP), transaminases enzymes- aspartate aminotransferases (AST) alanine (ALT) protein estimated. EOs observed showing toxicity (mint LC<sub>50</sub> = 5.9 μl/ ml LC<sub>50</sub>= 7.02 ml). Exposure altered significantly (p<0.01). also significant Thus, it is concluded that can be recommended as safe ecofriendly alternatives.
