摘要

Varroa destructor mites (Acari: Varroidae) are harmful ectoparasites of Apis mellifera honey bees. Female foundresses of wax-capped pupal host cells and their daughters feed on host fluids from open wounds on the host's integument. Details of V. destructor mite nutrition are forthcoming, and little is known about the potential physical effects on hosts from mite feeding. Chemical analysis of waste excretions can infer details of animals’ nutrition. Here, chemical analysis by high-performance liquid chromatography/mass spectrometry (HPLC-MS/MS) of mite excretions showed that the purine content of V. destructor waste consists of guanine with traces of hypoxanthine. Traces of uric acid and caffeine were also detected. Concentrations of guanine attenuated over time and excretions collected from senescing mites did not contain detectable guanine. Non-reproducing individual female mites maintained in vitro, housed in gelatin capsules and provided a honey bee pupa, deposited an average of nearly 18 excretions daily, mostly on the host's integument rather than on the capsule wall. The weight and volume of excretions suggest mites can consume nearly a microlitre of host fluids each day. Compounded over 10 days, this together with open wounds, could lead to substantial water loss and stress to developing pupae.

V.析构型营养的细节即将到来，关于来自螨虫喂养的潜在物理效应很少。废排泄的化学分析可以推断动物营养的细节。这里，通过高效液相色谱/质谱（HPLC-MS / MS）的螨虫排泄的化学分析表明，V.探测器废物的嘌呤含量由具有缺氧痕的鸟嘌呤组成。还检测到尿酸和咖啡因的痕迹。随着时间的推移和排泄物的诱惑诱导来自Sencing螨虫收集的排泄并不含有可检测的鸟嘌呤。在体外维持的不繁殖个体雌性螨虫，饲养在明胶胶囊中并提供蜂蜜蜂蛹，每天沉积平均近18个排泄，主要是在宿主的内容上而不是在胶囊壁上。排泄的重量和体积表明螨虫可以每天消耗几乎微液体液体。在10天内复合，这与开放的伤口一起可能导致显着的水分流失和对发展蛹的胁迫。
