(1)背景：番茄潜叶蛾Tutaabsoluta（鳞翅目：Gelechiidae）是一种重要的番茄害虫。目前，它被认为是欧洲、北非和中东各国的严重威胁。 T.absoluta 的广泛使用和对多杀菌素产生的耐药性引起了一些担忧，从而导致需要替代产品。 (2)材料和方法：进行了多项实验室实验来研究沸石颗粒膜对 T.absoluta 的杀卵特性。使用不同的暴露方法测定了三种不同的沸石和六种沸石制剂对 T.absoluta 卵和幼虫的毒性。 (3) 结果：一般来说，配制的沸石产生较高的卵和幼虫死亡率值，特别是当残留施用沸石颗粒膜时。与其他产品（例如高岭土、其配方产品 Surround 和杀虫剂多杀菌素）相比，接触沸石造成的死亡率存在显着差异。高岭土和 Surround 对两种施用方法都表现出很小或没有影响，而当局部施用多杀菌素时，孵化率降低了 95%。两种施用方法中，多杀菌素产生的卵和幼虫死亡率均为 100%。此外，在接触可湿性粉剂（WP）制剂的成虫中观察到产卵活性增加。这些可湿性粉剂制剂增加了卵的沉积，而 Surround 和多杀菌素则引发了负面的产卵反应。 (4)结论：由此可见，供试品BEA(Beta多晶型A)、FAU(八面沸石)、LTA(Linde A型)沸石及其制剂对赤蝽卵不具有真正的杀虫活性。然而，卵暴露于沸石似乎会削弱第一龄幼虫并增加其死亡率，从而影响发育过程。随后，根据选择试验，在处理过的叶子和对照叶子上产卵的数量之间没有观察到显着差异。
(1) Background: The tomato leafminer Tuta absoluta (Lepidoptera: Gelechiidae) is a key tomato insect pest. At present, it is considered to be a serious threat in various countries in Europe, North Africa, and Middle East. The extensive use and the developed resistance of T. absoluta to spinosad causes some concern, which leads to the need for alternative products. (2) Materials and Methods: Several laboratory experiments were conducted to investigate the ovicidal properties of a zeolite particle film on T. absoluta. The toxicity of three different zeolites and six zeolite formulations to T. absoluta eggs and larvae was determined using different exposure methods. (3) Results: In general, the formulated zeolites yielded higher egg and larvae mortality values, especially when the zeolite particle film was residually applied. Notable differences in mortality rates from exposure to zeolites compared to other products, such as kaolin, its formulated product Surround, and the insecticide spinosad, were observed. Kaolin and Surround exhibited little or no effect for both application methods, while the hatch rate was reduced by 95% when spinosad was applied topically. Spinosad yielded egg and larvae mortality rates of 100% for both application methods. Additionally, increased oviposition activity was observed in adults exposed to the wettable powder (WP) formulations. These WP formulations increased egg deposition, while Surround and spinosad elicited a negative oviposition response. (4) Conclusions: It can be derived that the tested products, zeolites BEA (Beta polymorph A), FAU (Faujasite), LTA (Linde type A), and their formulations, had no real insecticidal activity against the eggs of T. absoluta. Nevertheless, egg exposure to zeolites seemed to affect the development process by weakening the first instar larvae and increasing their mortality. Subsequently, based on the choice test, no significant difference was observed between the number of eggs laid on the treated leaves and control leaves.
