The indoor insecticidal effect of 3 kinds of 6 kinds of insecticides on the 3rd instar larvae of the tea caterpillars, the field control effect and their indoor insecticidal effects on the black coccidia and the cashmere had been measured. The results showed that the insecticides There were significant differences in indoor insecticidal effects between tea caterpillars and their natural enemies, and no significant differences in the control effects on tea caterpillars.2 The indoor insecticidal effects of 0.5% Kung-fu EC on the 3rd instar larvae of the tea caterpillars and the field control effects And the indoor insecticidal effect on the black coccidian beetle and the cashmere had 93.5%, 89.6%, 10 .0% and 5.7%, respectively; the 3.5% %, 10.4%, 6.6%; 80% of dichlorvos 200 times were 77.5%, 87.5%, 26.5%, 24.8%; 40% 0 0 0 times were 72.4%, 86.6%, 26.7%, 22.5% respectively; Bacillus thuringiensis bacilli powder 50 0 times of 1.16 × 10 11 spores · g-1 were 6 8.8 %, 86.0%, 5.3% and 4.7%, respectively. The 5 × 10 7 PIB · m L-1 Echinococcus multilocularis preparations were 66.6%, 85.5%, 3.6% and 3.8%, respectively. Control index analysis was used to establish the evaluation index of pesticide screening
