中文摘要:

柑橘大实蝇 Bactrocera minax (Enderlein)是一种为害柑橘类果实的毁灭性害虫。评价亚致死浓度的丁硫克百威和阿维菌素对其成虫运动行为的影响，可为预防和控制该害虫提供理论基础。本文通过不同亚致死浓度的丁硫克百威和阿维菌素处理柑橘大实蝇成虫，并于药后1 h和6 h检测其起飞率、水平和垂直爬行距离。结果表明，与空白对照组（CK）相比，LC5 、LC10 丁硫克百威处理后1 h的雌、雄虫起飞率分别显著降低66.7%、50.0%、43.3%和40.0%；LC5 丁硫克百威处理的成虫垂直爬行距离也明显降低34.6%，而LC10丁硫克百威处理的成虫水平爬行距离却显著增加24.7%。与空白对照组（CK）相比，LC5 、LC10 、LC25 阿维菌素的处理后1 h的柑橘大实蝇雌、雄成虫起飞率分别显著降低33.3%、23.3%、23.3%、33.3%、53.3%和46.7%；LC5 和LC25 阿维菌素处理的成虫水平爬行距离分别明显降低24.2%和38.0%。LC10和LC25 阿维菌素处理的成虫垂直爬行距离也分别明显降低25.2%和84.4%。结果还表明，丁硫克百威和阿维菌素对柑橘大实蝇成虫的水平爬行能力、垂直爬行能力和起飞能力的亚致死效应与其浓度相关。丁硫克百威的亚致死浓度处理对柑橘大实蝇成虫水平爬行能力的影响存在性别差异，而阿维菌素的亚致死浓度处理对该成虫起飞能力和水平爬行能力的影响亦存在性别差异。此外，丁硫克百威和阿维菌素对柑橘大实蝇成虫水平爬行能力和垂直爬行能力的亚致死效应与药剂处理后时间长短相关。

英文摘要:

The Chinese citrus fly, Bactrocera minax (Enderlein) is a highly destructive pest of citrus fruit. Evaluating the impacts of carbosulfan and abamectin at different sublethal concentrations on the movement behavior of B. minax adults will provide the theoretical basis for prevention and control of this destructive pest.In the present study, the take off rate and the horizontal and the vertical crawling distances of B. minax adults were detected at 1 h and 6 h after exposure to carbosulfan and abamectin at several sublethal concentrations. The results showed that the take off rates ofB. minax adults females and males treated by LC 5 and LC 10 of carbosulfan were significantly reduced by 66.7%, 50.0%, 43 .3% and 40.0% after 1 h, respectively, compared to the untreated group (CK). Comparson with CK, the horizontal crawling distances of B. minax adults treated by LC5 carbosulfan were significantly reduced by 34.6%, whereas their vertical crawling distances exposure to LC10 carbosulfan were significantly increased by 24.7% . The take off rates of B. minax adults females and males treated by LC5 , LC10 and LC25 of abamectin were significantly reduced by 33.3%, 23.3%, 23.3%, 33.3%, 53.3% and 46.7% after 1 h , respectively. Comparion with CK, the horizontal crawling distances of B. minax adults treated by LC5 and LC25 of abamectin were significantly reduced by 24.2% and 38.0%, respectively. The vertical crawling distances of B. minax adults treated by LC10 and LC25 of abamectin were significantly increased by 25.2% and 84.4%, respectively. Sublethal dose dependent effects of carbosulfan and abamectin to the take off rates, the horizontal crawling ability and the vertical crawling ability of B. minax adults were observed.There are gender differences for the horizontal crawling ability of B. minax adults after exposure to the sublethal doses of carbosulfan, whereas for the horizontal crawling ability and the vertical crawling ability of B. minax adults after exposure to the sublethal doses of abamectin. In addition, the horizontal crawling ability and the vertical crawling ability of B. minax adults are related to the time after exposure to the sublethal doses of carbosulfan and abamectin.
