室内条件下对七星飘虫（Coccinellaseptempunctata）幼虫、成虫和蛹的触杀毒力测定结果表明，不同发育阶段的七星瓢虫对20种杀虫剂的敏感度不同，以幼虫最敏感，成虫和蛹耐药性较强。所测20种杀虫剂对七星飘虫的毒性差异很大，结果为：高效氯氟菊酯、辛硫磷、甲基对硫磷、齐螨素和好年冬5种杀虫剂对七星部虫的成虫、幼虫和蛹均具有很大的毒性，在测试浓度下对成虫和幼虫的杀伤力均为100％，甲基对硫磷对蛹杀伤力在80％~100％。对七星瓢虫安全的药剂有：双甲脒、唑蚜威、杀虫双、灭幼脲、BT、抗蚜威、螨死净、抑食肼、吡虫啉和氟虫脲等10种，对幼虫杀伤力低于20％，对成虫和蛹杀伤力低于15％。其它5种药剂：达螨灵、硫丹、苯丁锡、噻嗪酮和尼索朗对七星瓢虫较为安全，对幼虫杀伤力为26．7~50％。
The results of in vitro test on the contact toxicity of larvae, adults and pupae of Coccinella septempunctata showed that the sensitivity of Coccinella septempunctata to 20 kinds of insecticides was different at different developmental stages. The larvae were most sensitive to adults and pupae Strong drug. The toxicity of the 20 insecticides measured on the fish starfishes vary greatly, the results were: high-performance cyfluthrin, phoxim, methyl parathion, Adults adults, larvae and pupae have great toxicity, killing adults and larvae at the test concentrations were 100%, methyl parathion on the pupal destructive power of 80% to 100%. The safety of the ladybug ladybugs are: amitraz, azoxystrobin, insecticidal double, bifonazole, BT, pirimicarb, mite dead net, inhibition of hydrazine, imidacloprid and flubendiocarb, 10 pairs of larvae Lethality is less than 20% and lethal to adults and pupae is less than 15%. The other five agents: daphnophylline, endosulfan, dibenzoprost, buprofezin and nisolone were more safe for Coccinella septempunctata, lethal to larvae was 26.7 to 50%.
