| dc.description.abstract | The effect of sub-lethal doses of decamethrin and carbaryl at their LD5, LD10, LD25 and LD50 levels on orientational stimuli, feeding, reproductive potential and survival of the three important pests of brinjal, namely, the epilachna beetle H.28 punctata, the aphidsA. gossypii and the leaf hopper A. b. bicuttula have been studied in the laboratory. In all the three test insects, positive orientational stimuli were not detected at all the tested sub-lethal levels of the two insecticides. A decrease feeding rate in H. 28 punctata was detected when the insects were exposed to the sub-lethal dose treatments. In A. crossypii and A. b. biguttula, the reduction in the feeding rate was more pronounced at the LD 50 level of both insecticides. | en_US |
