The objective of this study was to evaluate the toxicity and preference (oviposition and emergence of adults) of Zabrotes subfasciatus (Coleoptera:Chrysomelidae: Bruchinae) in Phaseolus lunatus grains with commercial essential oils of Acorus calamus, Betula lenta, Cinnamomum cassia and Citrus aurantium. The contact, fumigation and preference tests were carried out to check the effect of essential oils on the insects. In the contact and fumigation test the lethal concentrations LC50 and LC95 were determined. In the contact test (A) calamus was the most toxic with toxicity ratio 61.17. It has been found in the regression analyzes that increased concentrations of essential oils reduced the number of eggs and insects emerged. In the fumigation test, (B) lenta was the most toxic with toxicity ratio 86.2. The concentrations 0.2; 0.6; 25; 1.2 µL / 20 g of (A) calamus, (B) lenta, (C) aurantium and C. cassia provided a higher reduction of eggs and adult emergence in the preference test. The essential oils tested can be used in the control of Z. subfasciatus, resulting in mortality and reduction of oviposition and adults.

在用商业精油处理的菜豆中控制 Zabrotes subfasciatus（鞘翅目：Chrysomelidae：Bruchinae）

本研究的目的是评估 Zabrotes subfasciatus（鞘翅目：Chrysomelidae：Bruchinae）在使用菖蒲、白桦、肉桂和枳实的商业精油的菜豆谷物中的毒性和偏好（产卵和成虫出现）。进行接触、熏蒸和偏好测试以检查精油对昆虫的影响。在接触和熏蒸试验中，测定了致死浓度 LC50 和 LC95。在接触试验 (A) 中，菖蒲毒性最大，毒性比为 61.17。在回归分析中发现，增加精油浓度会减少卵和昆虫出现的数量。在熏蒸试验中，(B) lenta 毒性最大，毒性比为 86.2。浓度0.2；0.6; 25; 1. 2 µL/20 克 (A) 菖蒲、(B) 扁豆、(C) 枳壳和肉桂在偏好测试中提供了更高的卵和成虫羽化减少。所测试的精油可用于控制筋膜下皮癣菌，导致死亡率和产卵率和成虫减少。
