ABSTRACT
Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Homoptera: Liviidae) and citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) are imperative insect pests of citrus orchards due to their relation with bacterial diseases. The objective of this study was to evaluate the effectiveness of soil-applied insecticides against these insect pests. The results of present study showed that soil application of imidacloprid gave a significant control compared to other insecticides. The lowest population of both ACP adults (1.80/plant) and nymphs (10.4/plant) was observed after exposure to imidacloprid than the rest of the chemicals. Similarly, CLM larval population was also observed lower (1.13/plant) when imidacloprid was applied. The least affected chemical was spirotetramat, as the population of both pests was recorded higher on citrus plants after application of this insecticide compared to others. Our findings indicate that imidacloprid can be considered the best insecticide for managing CLM and ACP population in an integrated approach.
Novelty Statement | The present study will be helpful in the selection of effective insecticide for the management of two major insect pests of citrus orchards.
