Description :
Pesticides are used to kill the pests (harmful insects) in order to prevent the economic loss of the cultivators. The chemical pesticides have adverse effects on human health and on the environment. Biopesticides play a significant role in organic farming and in the integrated pest management (IPM) system. Pesticides of plant origin are a good alternative to the synthetic pesticides. In the present investigation, water extracts and methanol extracts from the leaves of Lantana camara (L.) were tested for their insecticidal property on Callosobruchus macullatus (Pulse beetle) under laboratory conditions. C. macullatus is commonly known as pulses beetle. C. macullatus is a serious post-harvest pest that attacks the economically important legumes especially pulses. It is a common pest of stored legumes that has a cosmopolitan distribution. Cowpea seed beetles were treated with different concentrations viz. 0.02%, 0.04%, 0.06%, 0.08%, 0.1% and 0.2% of L. camera methanol leaf extracts. The conc. 0.02%,0.04%,0.06% did not show any significant mortality against of C.macullatus while 0.08% shown high mortality and 0.1% and 0.2% shown total mortality. The conc. of 0.08, 0.1%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5% of L. camera water leaf extracts were tested against the C.macullatus. 1% and 1.5% shown high mortality while 2.0% and 2.5% of L. camera water leaf extract shown total mortality. Thus, at the higher concentration extracts of L. camera can act as a potential pesticide.
