摘要： It has been reported that host plants are able to mediate the interactions between insect herbivores and entomoviruses, but how plants affect growth, development, detoxifying enzymes and metabolic enzymes of herbivores infected by entomoviruses has only rarely been studied so far. We compared growth, development duration, activity of a detoxifying enzyme (carboxylesterase) and a metabolic enzyme (acetylcholinesterase) of a caterpillar (Spodoptera exigua) infected with an entomovirus (SeMNPV) or left non-infected that were fed one of four plants (Ipomoea aquatica, Brassica oleracea, Glycine max or Zea mays). Developmental duration was shorter but growth (length, mass) and enzyme activities were higher in NPV-infected caterpillars fed I. aquatica or B. oleracea than those fed G. max or Z. mays. This study suggests that host plants influence the growth impacts of entomoviruses on herbivores by affecting the enzymes of herbivores.
