| 摘 要： | 机敏漏斗蛛（Aqelena difficilis）,在山东省日照市沿海地区1年发生1代,以不同的若蛛在林下杂草、枯枝落叶丛、石块下越冬。翌年4月上旬出蛰活动,若蛛经8龄,6月下旬发育至成蛛,7月上旬开始交配,8月上旬开始产卵,孵化若蛛,10月下旬开始越冬。卵期10.4天,成蛛期69天。雌雄比4：1,是多种害虫的重要天敌。该蛛发生与海拔、农药、天敌、风雨等外界因子关系密切。封山育林,严禁放牧、烧荒,禁用化学农药,是保护成若蛛、扩大繁殖的关键。 |

| Abstract: | Aqelena difficilis has one generation a year in southeast littoral of Shandong,China.Overwinter takes place as larva in the woods or weeds,emergence in early April the next year and mating occurs in early July after seven instars;oviposition occurs and hatching in early August;winter takes place in late October.Its average incubation period is 10.4 days,adult period 69 days.Its number ration of male to female is 4︰1.It is an important natural enemy of various insect pests.The outbreak of the spider has a close relationship with altitudes,chemical insecticide and natural enemy.Closing hillsides and planting trees with prohibition of using chemical insecticide is the key to protect them. |
