; Death events: in the general cases （survived in 2- 14 d）, the serum levels of EGF and CRP had no change or mildly increased and were reacted stagnantly; In special cases （survival time less than 2 d）, both of them increased quickly and then declined rapidly until death.

CRP的变化与之正好相反，且两者之间呈现明显的负相关（r=-0.774，P〈0.01）；死亡组：在一般死亡病例（生存时限2～14天）中，两者不升高或轻度升高，反应迟滞；在特殊死亡病例（生存时限小于2天）中，两者快速升高而后急速下降直至死亡。

Plutella xylostella larvae of a strain highly resistant to spinosad were used as hosts to rear the parasitoid Cotesia plutellae. When the parasitoids had developed to the stage of early instar larva, the host larvae were treated with 50 mg/L spinosad on the terga by topical application and then fed with cabbage leaves treated with 50 mg/L spinosad to allow the host larvae and the parasitoid larvae to develop. Three days after treatment, the parasitoid larvae inside the host were collected by dissecting the host larvae. The body fluid of P. xylostella and the bodies of parasitoid larvae were then analyzed with HPLC. Both of the active components, spinosyn A and spinosyn D, of spinosad were detected in the body fluid of host larvae and in the bodies of parasitoid larvae, and the residue concentrations were 2.79 mg/L and 0.94 mg/L in the host and the parasitoid respectively.

以对多杀菌素高抗的小菜蛾Plutella xylostella幼虫作为菜蛾绒茧蜂Cotesia plutellae的寄主，待绒茧蜂发育到1龄幼虫时，将浓度为50 mg/L的多杀菌素点滴到寄主幼虫背板上，随后让寄主幼虫取食经50 mg/L多杀菌素处理过的甘蓝叶片，寄主幼虫和其体内的蜂幼虫再发育3天后，将寄主幼虫解剖取出蜂幼虫，用高效液相色谱法对经多杀菌素处理的小菜蛾幼虫体液以及绒茧蜂幼虫匀浆液进行检测，结果多杀菌素的2个活性成分spinosyn A和spinosyn D均被检测到，两者的多杀菌素残留浓度分别是2.79 mg/L和0.94 mg/L。
