用核型多角体病毒产物吉普切克对马里兰州东部和北部的中高密度吉普赛蛾种群进行了空气处理。以Orzan LS(6%重量/体积)作为防晒剂，Pro Mo液体补充剂(体积分数为12.5%)作为取食促进剂和保湿剂，Rhoplex B60A(体积分数为2%)作为贴剂，以每公顷18.7升和1.25×1012个多面体包涵体的速度在9个林地上喷洒两次。与对照林地的数量相比，这一比率使马里兰州东部的卵块数量减少了98%，马里兰州北部的减少了80%。喷施林地和对照林地的落叶差异均不显著。
Moderate to high density gypsy moth, Lymantria dispar L., populations in eastern and northern Maryland were aerially treated with the nucleopolyhedrosis virus product, Gypchek. A tank mix containing Orzan LS (6% wt/vol) as a sunlight protectant, Pro Mo liquid supplement (12.5% by vol) as a feeding stimulant and humectant, and Rhoplex B60A (2% by vol) as a sticker was applied twice to nine woodlots at the rate of 18.7 liters and 1.25 × 1012 polyhedral inclusion bodies per ha per application. Compared with numbers in control woodlots, this rate reduced numbers of egg masses by 98% in eastern Maryland, and by 80% in northern Maryland. Differences in defoliation between sprayed and control woodlots in either area were not significant.
