Laboratory assessment of different botanical extracts and cypermethrin against insect pests

Muhammad Naeem, Syed Ishtiaq Anjum, Muhammad Ismail, Jehangir Khan, Saima Bibi, Abdussalam

Different botanical extract contains promising pest control substances which are effective against many economically important insects pest of crop and store grain pests. So a comparative study was conducted to assess the contact toxicities of Cypermethrin against important stored products insects, Sitophilus oryzae, the rice weevil, and Tribolium castaneum, the rust red flour and 4th instar larvae of Culex pipen. The rice weevil, Sitophilus oryzae were more susceptible than T. casteneum and rust red flour beetle, with LC50 values of 0.05% and 0.09% respectively. Aqueous extract of Vitex negundo showed moderate activity against T. castaneum and non significant activity against S. oryzae. The extracts of Nepeta Clarkei showed activity against the 4th instar larvae of Culex pipien with LC50 value of (1.5%). Similarly, effects of Vitex negundo against Culex pipien larvae were not significant. Larvicidal effects of these botanicals were considered to warrant further research into their potential for commercial use.
