Improved variety of Hippophae rhamnoides was introduced into Sunwu from Russia in 1996.There are many species of pest insects damaging Hippophae rhamnoides such as Orgyia aantigua,Lymantria dispar,Malacosoma neustria festacea,Capitophorus sp．Halyomorpha halys and Rubiconia intermedia.In 1999,25%benzoylphenal urea Ⅲ was applied against the pest insects mentioned above and the result showed its control effect was significant.%1996年孙吴县从俄罗斯引进沙棘Hippophae rhamnoides L.良种，由于沙棘是经济作物，且有古毒蛾、舞毒蛾、黄褐天幕毛虫、沙棘蚜虫、茶翅蝽、珠蝽等诸多害虫危害。1999年引进高效、低毒、无污染的25%灭幼脲Ⅲ号进行防治实验，实验证明25%灭幼脲Ⅲ号对诸多沙棘虫害防治效果明显。
