Green prevention and control method for hylocereus oryzae of jackfruit

Abstract

The invention relates to a green prevention and control method for jackfruit hylocereus oryzae, a food-sourced attractant is adopted to trap and kill adults, and the food-sourced attractant is prepared from jackfruit essence, brown sugar, white vinegar, 75% alcohol and water according to the mass ratio of (0.4-0.6): 10: 20: 10: 80. The method for trapping and killing adults by using the food-derived attractant comprises the following steps: (1) preparing the food-derived attractant according to the composition proportion; (2) suspending for trapping and killing adults: suspending a trap at the height of 1.2-1.5 m on the trunk of the jackfruit tree, wherein 100-150ml of food-derived attractant is filled in one trap; and (3) replacing the food source attractant in time. The method can effectively control the occurrence of the hylocereus flabellatus in the jackfruit garden, reduces the use of chemical pesticides, protects the ecological environment of the jackfruit garden, and improves the quality of jackfruit fruits.

Description

technical field [0001] The invention relates to a comprehensive prevention and control method for plant diseases and insect pests, in particular to a green prevention and control method for jackfruit and yellow-winged silk borer. Background technique [0002] Jackfruit (scientific name: Artocarpus heterophyllus Lam) belongs to the fruit tree of the genus Jackfruit of the family Moraceae. It is a world-renowned tropical fruit and is widely planted in tropical regions. It is cultivated in tropical and subtropical regions in Hainan, Guangdong, Guangxi and Fujian, southeastern Yunnan, and southern Sichuan. , In the past 10 years, the planting area of ​​jackfruit in my country has increased at an annual rate of 15%, and the industry has developed rapidly. With the improvement of the scale of jackfruit development and the acceleration of the process of improving varieties, diseases and insect pests have become important factors restricting the healthy and sustainable development of...

Problems solved by technology

The damage method of the yellow-winged silk borer is that the female adult lays eggs on the surface of the host's young shoots, fruit stalks or flower buds. After hatching, the larvae feed on the surface of the tissue nearby, and after about 2 instars, they eat into the shoots, flower buds and fruits. , the insect is not easy to find in the early stage of the damage, which lays a favorable foundation for its outbreak; if it is not properly controlled in the adult stage or the first instar larval stage, it will be difficult to carry out the control or the control effect will be poor after it has bored into the fruit or inflorescence in the later stage. prone to outbreaks

At present, the prevention and control of the yellow-winged silk borer mainly adopts chemical pesticides and traditional green prevention and control methods, such as food-source sweet and sour liquid attractants, etc. The increase in the use of chemical pesticides has seriously damaged the ecological environment of the orchard, and the pesticide residues in the fruit exceed the standard. The problem of unsatisfactory effect and increased production cost, so it is particularly important to find a green prevention and control method with good control effect
