Harmless ecological prevention and control method of conopomorpha sinensis bradley

Abstract

The invention provides a harmless ecological prevention and control method of conopomorpha sinensis bradley. The method is characterized in that the generation of conopomorpha sinensis bradley is divided into four stages, namely the interval stage, the initial generation stage, the peak stage and the post-peak stage, and the ecological prevention and control method is designed for each generationstage. The method focuses on comprehensive prevention and control and has better sustainability and a good production and application effect, and conopomorpha sinensis bradley can be controlled in a range of an economic hazard threshold value. The method has great significance in improvement of the edible property of litchis, longan and other damaged fruits, increase of the economic values of thelitchis, the longan and other damaged fruits and environmental protection.

Description

technical field [0001] The invention relates to a method for harmless ecological prevention and control of the scatter moth, which belongs to the field of agricultural insect and pest control. Background technique [0002] Yawen moth, Lepidoptera, Mothidae, also known as litchi pedicle borer. Distributed in the main producing areas of litchi in China, India, Thailand, South Africa and so on. It not only damages litchi, but also seriously damages longan, green plum and mango. According to the survey in the longan garden of South China Agricultural University, 48% of longan fruit drop is caused by pedicle borers; it not only seriously damages fruits, but also damages tender stems, Tender leaves, flower spikes. In the later period, it harms the tender stems and young leaves. The insect uses larvae to bore into the top of the tender stem and the midrib of the young leaves. The top of the damaged shoots dies, the midrib of the damaged leaves turns brown, and the epidermis ruptu...

AI Technical Summary

Problems solved by technology

In the later period, it harms the tender stems and young leaves. The insect uses larvae to bore into the top of the tender stem and the midrib of the young leaves. The top of the damaged shoots dies, the midrib of the damaged leaves turns brown, and the epidermis ruptures. In the flowering stage, the insect damages the flower spikes, and the larvae drill into the flowers. The tender stem of the ear is near the top, causing the flower ear to dry and wilt and harm the fruit during the fruit stage. The young fruit eats the core during the expansion stage, resulting in fruit drop. After the fruit develops to color, eggs are laid at the crack near the fruit base, and the larvae hatch Afterwards, the seed stalks are eaten directly from the eggs bored into the fruit, and the insect feces are left in the stalks, which not only affects the fruit development, but also causes pre-harvest fruit drop, and more seriously affects the quality, resulting in a substantial drop in income.
