白刺萤叶甲(Di(?)h(?)da r(?)a(?))是内蒙古西部草原植物白刺(Nitraria (?)ca)的生活重要害虫。成虫和幼虫取食其幼芽、嫩叶和叶片,幼虫排出大量粪便污染枝条,严重影响白刺生长发育。该虫一年发生2代,以成虫在白刺根际周围土壤中越冬。越冬代成虫4月下旬开始出土,5月上、中旬为盛期、一代幼虫6月中、下旬大量发生为害,7月上、中旬一代成虫盛发。二代幼虫8月中、下旬大量发生。40％复果乳油、20％速灭杀丁乳油和50％杀虫双水剂对成、幼虫有良好防治效果。5月上旬为越冬代成虫始盛期,6月上、中旬为一代幼虫孵化盛期。目前,对此虫的预报主要是做好田间调查。
Diabrotica (Di (?) H (?) Da? (?) A (?)) Is an important pest of life in Nitraria (?) Ca, a prairie plant in western Inner Mongolia. Adult and larvae feed on their sprouts, young leaves and leaves, larvae excrete a large number of excrement contaminated branches, seriously affecting the growth and development of Nitraria. The pest occurs two generations a year, in order to adult white winter prickly heat in the soil around the rhizosphere. Overwintering adult adults began unearthed in late April, mid May, mid-peak period, a generation of larvae in mid-June, late a large number of pest damage, in July, the middle and upper generation of adult rumble. Second-generation larvae in mid-August, a large number of late. 40% Fusong EC, 20% DME and 50% Pesticide Shuangshishingcheng, larvae have good control effect. Early May is the beginning of the overwintering adult adults peak, June, mid-generation larvae hatch peak. At present, the predator of this insect is mainly to do field investigation.
