我们测试了吸引力有毒糖诱饵（ATSB）与大蒜油微胶囊在β-环糊精作为活性成分对白纹伊蚊在海法郊区，以色列的有效性。两个三英亩的花园里有大量的Ae。选择白纹伊蚊用ATSB和ASB（不含活性成分的诱饵）进行周边喷雾处理。诱饵用食用染料染色以验证蚊子的进食。通过人类登陆捕获量和周围植被中的扫网捕获量来监测蚊子种群。实验持续了44天。治疗在第13天进行。蚊子种群在治疗后约4天崩溃，并持续稳定下降27天，直到研究结束。在实验地点，平均治疗前着陆率为每5分钟17.2次。治疗后两天，着陆率下降到11.4，并在接下来的26天内继续下降到平均2.6。在同一时期，对照种群稳定。很少有喂糖的雌性（8-10%）接近人类诱饵，蒽酮测试显示它们的作物/肠道内含有相对少量的糖。在我们的人类诱饵附近捕获的大约60- 70%的雄性是糖阳性的，这可能表明雄性是为了交配相关的行为而以糖为食。从有毒诱饵处理的植被中，我们回收了显着较少（约10-14%）的男性和女性比ASB处理的对照染色的ATSB。这可能表明有毒诱饵改变了中毒蚊子在植被中的休息行为。几乎没有Ae。经ATSB处理后，白纹伊蚊雌蚊（5.2 ± 1.4）只趋饵。因此，微胶囊化大蒜油是一种有效的杀虫剂。当在ATSB系统中使用时，
We tested the efficacy of attractive toxic sugar bait (ATSB) with garlic oil microencapsulated in beta-cyclodextrin as active ingredient against Aedes albopictus in suburban Haifa, Israel. Two three-acre gardens with high numbers of Ae. albopictus were selected for perimeter spray treatment with ATSB and ASB (bait containing no active ingredient). Baits were colored with food dye to verify feeding of the mosquitoes. The mosquito population was monitored by human landing catches and sweep net catches in the surrounding vegetation. Experiments lasted for 44 days. Treatment occurred on day 13. The mosquito population collapsed about 4 days after treatment and continued to drop steadily for 27 days until the end of the study. At the experimental site the average pre-treatment landing rate was 17.2 per 5 mins. Two days post-treatment, the landing rate dropped to 11.4, and continued to drop to an average of 2.6 during the following 26 days. During the same period, the control population was stable. Few sugar fed females (8–10%) approached a human bait and anthrone tests showed relatively small amounts of sugar within their crop/gut. Around 60–70 % of males caught near our human bait were sugar positive which may indicate that the males were feeding on sugar for mating related behavior. From the vegetation treated with the toxic bait, we recovered significantly fewer (about 10–14%) males and females stained by ATSB than at the ASB-treated control. This may indicate that the toxic baits alter the resting behavior of the poisoned mosquitoes within the vegetation. Almost no Ae. albopictus females (5.2 ± 1.4) approached human bait after treatment with ATSB. It therefore appears that microencapsulated garlic oil is an effective pesticide against Ae. albopictus when used in an ATSB system.
