将根虫瘟霉释放到卢塞恩作物中，用于三叶苜蓿蚜的生物防治。斑点。在一个网站的动物流行病开始，高达88%的感染被记录在3米的释放点。在动物流行期间没有降雨记录，疾病传播可能与夜间长时间的高湿度有关。总结了其他4个研究中心的数据。这种疾病没有发生在其他蚜虫上，但在明显没有宿主的情况下，可能作为休眠孢子在一个地点持续数月。尽管使用了高湿度的田间笼，但田间感染的初始水平通常较低。一种方法，预计将提高这种初始感染率的描述。
An exotic pathogen, Zoophthora radicans was released into lucerne crops for the biological control of Therioaphis trifoli f. maculata. At one site an epizootic was initiated, with up to 88% infection being recorded within 3 m of the point of release. No rain was recorded during the epizootic and disease transmission could be correlated with prolonged periods of high humidity at night. Data from 4 other sites are summarised. The disease did not occur on other aphids but has persisted, probably as resting spores, at one site for many months in the apparent absence of the host. Initial levels of field infection have been usually low despite the use of a high humidity field cage. A method which is expected to improve this initial infection rate is described.
