沙潜Opatrums Subaratum Fald.是我国北方干旱区重要的苗期害虫,危害严重。一年完成一个世代,成虫在土中或缝隙处越冬。早春出蛰,4月上旬至5月中旬为活动盛期。成虫取食的寄主植物有34科110余种,主要为种子和幼苗,经多年观察,成虫对豆饼、花生饼和棉子饼有趋性。成虫耐饥能力很强,寿命长,且能进行产雌雄孤雌生殖。在适宜温度下卵期随温度升高而缩短,卵期4～28天。幼虫在表土层活动,经6龄或7龄,幼虫期48～53天,地势高排水良好的土壤有利于幼虫的生长发育,幼虫在5～8厘米土层中化蛹,蛹期7～11天.沙潜主要天敌是步行(虫甲)、地蝼(虫甲),食量很大。
Submarine Opatrums Subaratum Fald. Is an important seedling pest in the northern arid region of China, which is seriously endangered. One year to complete a generation, adult wintering in the soil or crevice. Early spring hibernation, early April to mid-May for the peak activity. There are 34 families of more than 110 species of host plants, mainly seeds and seedlings. After many years of observation, adults have the tendency of bean cake, peanut cake and cotton cake. Adult strong resistance to hunger, long life, and can produce male and female parthenogenesis. Egg temperature at appropriate temperatures with the shortening of the temperature rise, the egg period of 4 to 28 days. The larvae are active in the topsoil, 6 or 7 years old, larvae of 48 to 53 days, the high drainage of good soil is conducive to the growth and development of larvae, larvae in 5-8 cm soil layer pupation, pupal stage 7 ~ 11 Days. The main natural enemies of sand dunes are pedestrians (pests), tortoise (pest), food intake is large.
