Abstract

Fourteen cations were tested at a 1% concentration (wt:wt), as chlorides, for their effects on the biological activity of the gypsy moth, Lymantria dispar (L.), nuclear polyhedrosis virus (LdMNPV). Cupric chloride was toxic to gypsy moth larvae. Ferrous and ferric chloride were inhibitory to larval growth and development as well as to virus activity. Strontium chloride was inhibitory to virus activity but had no apparent effects on gypsy moth larvae. Six cations had little or no effect on virus activity (i.e., calcium, lanthanum, magnesium, nickel, potassium, sodium), whereas four cations (i.e., cobalt, manganese, ruthenium, zinc) acted as viral enhancers, as indicated by reductions in LC50s.

摘要

以氯化物形式对14种阳离子进行了1%浓度（重量比）的测试，以研究它们对舞毒蛾核型多角体病毒（LdMNPV）生物活性的影响。氯化铜对舞毒蛾幼虫有毒。氯化亚铁和氯化铁抑制幼虫生长发育以及病毒活性。氯化锶抑制病毒活性，但对舞毒蛾幼虫无明显影响。6种阳离子对病毒活性几乎没有影响（即钙、镧、镁、镍、钾、钠），而4种阳离子（即钴、锰、钌、锌）作为病毒增强剂，表现为半数致死浓度（LC50）降低。
