摘要

本研究模拟了在蜜蜂觅食时,磺基恶氟和氟硝胺对棉蚜的真实田间暴露。磺基恶氟和氟硝胺对棉蚜48株田间药效的半田间试验 暴露h的总体平均死亡率在2020年季节分别为62.50%和63.50%,在2021年季节也分别为60.50%和62.50%。磺恶氟的致死时间值(LT1)范围为51.33–32.46天,氟硝胺为49.00–39.55天。对5岁觅食蜜蜂(~21天大)的实验室试验 与2020年季节的氟硝胺(2.75%)相比,暴露h显示磺基沙氟隆(5.00%)的总体平均死亡率优异。同样,在2021年的季节,磺基恶唑烷(4.75%)超过了氟硝胺(2.75%)。氟虫腈和氟硝胺对蜜蜂的最高LT1s分别达到27.45天和10.94天。国际生物控制组织将这两种杀虫剂分类为对蜜蜂无害。暴露于LD50测试杀虫剂的存活觅食蜜蜂的畸形消化道在暴露一周后逐渐消失。对于这两种杀虫剂,都提到了在花期前停止叶面喷雾的建议。

Residual toxicity of selected insecticides on Aphis gossypii and their safety limits on honeybees
Evaluation studies were carried out to simulate realistic field exposures of sulfoxaflor and flonicamid against Aphis gossypii at foraging time of Apis mellifera. Semi-field trials of field rates of sulfoxaflor and flonicamid against A. gossypii laboratory strain at 48 h of exposure had equipollent overall mean of mortality of 62.50 and 63.50%, respectively in season of 2020, likewise 60.50 and 62.50%, respectively in season of 2021. Lethal time values (LT1) had ranges of 51.33–32.46 days for sulfoxaflor and 49.00–39.55 days for flonicamid. Laboratory trials on foraging honeybees (∼21 days old) at 5 h of exposure showed an excellence for sulfoxaflor (5.00%) in overall mean of mortality compared to flonicamid (2.75%) in season of 2020. Likewise, sulfoxaflor (4.75%) surpassed flonicamid (2.75%) in season of 2021. The highest LT1s on honeybees for sulfoxaflor and flonicamid reached 27.45 and 10.94 days, respectively. International Organization for Biological Control classified both insecticides to be harmless on honeybees. Survival foraging bees exposed to LD50s of the tested insecticides had malformed digestive tracts gradually vanished along week of exposure. Suggestions for foliar spray stoppages prior to flowering period were mentioned for both insecticides.
