Abstract

 The crapemyrtle APHID, Tinocallis kahawaluokalani Kirkaldy, is an important pest of or namental woody plant, LAGERSTROEMIA spp. causes premature drop of leaves and decline of summer flowering and reduces the commercial market. Effect of BOTANICAL INSECTICIDE, PALIZIN at the recommended concentrations of 1500, 2000 and 2500 ppm evaluated on APHID and its predator, Harmonia axyrid is Pallas. Experiment was done on APHIDs by two methods leaf dipping and spraying and then the numbers of dead APHIDs were recorded at 24 after treatment. The results showed that spraying method was more effective than other method and caused 86.6%, 90% and 95% mortality at 1500, 2000 and 2500 ppm of PALIZIN, respectively. By dipping eggs of COCCINELLID in insecticide solutions the low esteggs hatching percent (50%) and the longest developmental period (19 days) were observed at 2500ppm of Paliz in. Eggs hatching percent and developmental period were slightly affected by 1500 ppm of PALIZIN in comparison with the control. By topical application of PALIZIN on the fourth instar larvae, the survival of larvae and pupal developmental period were not significantly affected. However, thehighest survival of treated fourth instar larvae (96.9%) than control (100%) was observed at 1500 ppmof PALIZIN. According to the results, PALIZIN at 1500 ppm had remarkable mortality on APHIDs without affecting many of tested characteristics of H. axyridis. So, PALIZIN at 1500 ppm can be used forintegrated pest management in integration with H. axyridis to control of T. kahawaluokalani.
