Abstract

In order to compare the effects of four conventional INSECTICIDES for controlling, alfalfa weevil Hypera postica, on MORTALITY and LONGEVITY of parasitoid BATHYPLECTES CURCULIONIS (Thompson), a laboratory investigation has been carried out in a RCBD design with 9 treatments and 3 replicates.The parasitized larvae of alfalfa weevil treated with following INSECTICIDES: [Check, treated with water (t1 )], chlorpyrifos 0.1% (t2), chlorpyrifos 0.2% (t3), etrimfos 0.05% (t4). etrimfos 0.1% (t5), malathion 0.15% (t6). malathion 0.3% (t7), phosalone 0.125%(t8) and phosalone 0.25% (t9).According to IOBC/ WPRS classification, t7 which caused 89.7% MORTALITY was the most and t2 caused 31.4% MORTALITY was the least harmful INSECTICIDES for larvae of parasitoid, when it was present in its host. The percentage of MORTALITY for tl to t9 were 5.7, 31.4, 52.6, 67.5. 83.2, 62.5, 89.7, 50.5 and 65.0 respectively. LONGEVITY offemale parasitoids in these treatments were 1].4, 7.6, 7.5, 7.0, 6.1, 7.0, 6.62, respectively.This study has also shown that there is no significant difference at P=5% among MORTALITY of pest at recommended or reduced dose in t4-t5 and t6-t7, however, significant difference observed for MORTALITY of parasitoid in these treatments.
