Abstract:As an important worldwide stored grain and product pest, Tribolium castaneum is very difficult to control. The toxicity influences of 4 kinds of plant water extracts on two chemical insecticides, 40% phoxim EC and 5% cypermethrin EC, tomato stems and leaves, reed whole plant, metasequoia leaves and honey locust fruits were determined. The results showed that all mixtures of plant water extracts and 40% phoxim EC 1000 times diluent or 5% cypermethrin EC 500 times diluent in different proportions gavevarious degrees of synergy. When the ratios of insecticides diluent to plant water extracts were 4:1 or 1:1 in volume, the synergies were significant.
