Scope

Scope: This document specifies the technical methods and monitoring methods for the release of Scleroderma guani (hereinafter referred to as "swollen-leg bee") in coffee plantations to control Xylotrechus quadripes (hereinafter referred to as "coffee borer beetle"). This document applies to the release technology and evaluation of the control effect of Scleroderma guani in controlling Xylotrechus quadripes in small-grain coffee plantations in Yunnan; Main technical content: 1. Terms and definitions: The following terms and definitions apply to this document. 1.1 Scleroderma guani Belongs to the family Bethylidae of the order Hymenoptera, and is an important parasitic predator of pests such as bark beetles. It plays a crucial role in controlling the harm caused by bark beetles. 1.2 Xylotrechus quadripes Belongs to the family Cerambycidae of the order Coleoptera, and is a major boring pest of more than 10 plants, including small-grain coffee, jackfruit, guava, water hyacinth, thick-barked trees, and teak (see Appendix A). 2. Control techniques 2.1 Control targets Used to control the larvae and pupae (larvae and pupae forms shown in Appendix B) of Xylotrechus quadripes that damage coffee trunks. 2.2 Pest survey 2.2.1 Survey time: Conduct surveys every 30 days from April to October each year. 2.2.2 Survey method: Before releasing the bees, set up standard plots in the areas where Xylotrechus quadripes occur. Within the standard plots, select 20 sample trees along the diagonal to survey the infestation rate of Xylotrechus quadripes, in order to determine the release quantity of bees. 2.3 Bee release 2.3.1 Optimal release period: The best time for releasing bees is from June to November, when the average temperature in the forest is above 25°C. 2.3.2 Release time and frequency: Select a sunny and windless day with a temperature of 25°C to 28°C for releasing bees. The interval between releases should be 60 to 90 days. 2.3.3 Release quantit
