毒蛾脂肪体的感染。小孢子虫（polysporidium vairmorpha disparis）对寄主幼体激素（JH）代谢有严重影响。感染后8 d，感染幼虫血淋巴中JH降解酶JH酯酶活性显著低于未感染幼虫。随着微孢子虫病的进展，活性仍然很低。感染幼虫的JH滴度略有升高；在大多数情况下，这种差异并不显著。这种JH代谢紊乱可能是由于脂肪体功能普遍受损和发展中的病原体对资源的高需求。(C) 2012爱思唯尔公司版权所有。
Infection of the fat body of Lymantria dispar (Lep.: Lymantriinae) larvae with the microsporidium Vairimorpha disparis has severe effects on juvenile hormone (JH) metabolism of the host. Beginning 8 days postinfection, activity of the JH degrading enzyme JH-esterase was significantly lower in the hemolymph of infected than uninfected larvae. Activity remained low as microsporidiosis progressed. JH titers were slightly elevated in infected larvae; the difference was not significant in most cases. This disturbance of JH metabolism may be due to generally impaired fat body functions and high demand for resources by the developing pathogen. (C) 2012 Elsevier Inc. All rights reserved.
