Abstract

Whiteflies greatly contribute to low yields and quality in tomato production. Continuous use of synthetic pesticides leads to whiteflies developing resistance to these pesticides. This research aimed at promoting the use of rabbit urine as a biopesticide against whiteflies in tomato production. Although rabbit urine is been used as a biopesticide against different pests, the best concentration to control whiteflies in tomato production is unknown. Six treatments compared in the two experiments of this study included: 2 L rabbit urine : 9 L water; 2 L rabbit urine : 6 L water; 2 L rabbit urine : 3 L water; 2 L rabbit urine : 0 L water; 0 L rabbit urine : 2 L water, and 20 mL Duduthrin 1.75EC : 20 L water. The first experiment was conducted in a randomized complete block design with six treatments and four blocks to investigate the effects of rabbit urine on the control of whitefly eggs, nymphs, and adults. The second experiment was conducted in a completely randomized design to determine the effect of rabbit urine on the bioactivity of adult whiteflies. Results indicated that plots treated with rabbit urine foliar spray registered reduced populations of whitefly eggs, nymphs, and adults, and lower LT50 values of repelling and killing compared to the negative control (0 L rabbit urine : 2 L water). However, a high ratio of rabbit urine caused significant scorching to tomato leaves. A solution of 2 L rabbit urine : 6 L water optimally controls whiteflies without scorching the plant foliage. Rabbit urine has both repelling and killing effects on whiteflies. In the future, further research can be conducted to investigate the effect of rabbit urine on populations of other important insect pests of tomato.

番茄（Solanum lycopersicum L.）上粉虱种群对兔尿叶面喷洒剂的反应

粉虱是番茄生产中产量和质量低下的主要原因。持续使用合成杀虫剂会导致粉虱对这些杀虫剂产生抗药性。这项研究旨在推广使用兔尿作为生物杀虫剂，以防治番茄生产中的粉虱。虽然兔尿已被用作防治不同害虫的生物农药，但控制番茄生产中粉虱的最佳浓度尚不清楚。本研究的两项实验中比较了六种处理方法，包括2 升兔尿：9 升水；2 升兔尿：6 升水；2 升兔尿：3 升水；2 升兔尿：4 升水；2 升兔尿：5 升水：3 升水；2 升兔尿：0 升水；0 升兔尿：2 升水，以及 20 mL Duduthrin 1.75EC：20 升水。第一项实验采用随机完全区组设计，共设四个区组六个处理，研究兔尿对防治粉虱虫卵、若虫和成虫的影响。第二项实验采用完全随机设计，以确定兔尿对粉虱成虫生物活性的影响。结果表明，与阴性对照（0 升兔尿：2 升水）相比，使用兔尿叶面喷洒的地块的粉虱卵、若虫和成虫数量减少，驱避和杀灭的 LT50 值降低。然而，高比例的兔尿对番茄叶片造成了明显的烧焦。2 升兔尿兑 6 升水的溶液能最有效地控制粉虱，而不会使植物叶片焦枯。兔尿对粉虱具有驱避和杀灭作用。今后，还可以进一步研究兔尿对番茄其他重要害虫种群的影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
