Abstract

Orius insidiosus, known as the pirate bug, is widely distributed throughout the Americas. It is employed for the biological control of Frankliniella occidentalis in organic berry crops in Mexico. In conventional crops, spinosad is the main control method for this pest. The LD50 of spinosad on O. insidiosus was determined. In addition, we monitored the population density of F. occidentalis in blackberry crops under two types of management (biochemical+mass trapping, and biological control). The LD50 was 225.65 ppm 3.8 times greater than the 60 ppm dose commonly used in blackberry crops. Both types of control are efficient; however, spinosad is less effective and should be combined with other environmentally friendly strategies. The possibility of combining chromatic traps+spinosad application and chromatic traps+strategic release of O. insidiosus to effectively control thrips without compromising fruit quality is discussed.

实验室和野外与棘球菊接触对隐孔螟死亡率的影响及其防治西富兰克林蝇的效果观察。
Orius insidiosus,被称为海盗虫,广泛分布在整个美洲。该方法用于墨西哥有机浆果作物的西富兰克林菌生物防治。在常规作物中,多酚是防治这种害虫的主要方法。测定了棘糖苷对毒蛾的LD50。此外,我们还监测了两种管理方式(生化+质量诱捕和生物防治)下黑莓作物中西叶蚜的种群密度。LD50为225.65 ppm,是黑莓作物中常用的60 ppm剂量的3.8倍。这两种控制都是有效的;然而,spinosad效果较差,应与其他环境友好型战略结合使用。探讨了色诱+施棘糖和色诱+策略放生在不影响果实品质的前提下有效防治蓟马的可能性。
