Embodiment 1

[0031] Example 1: Effects of different oviposition plants of Lygus tabacum on its oviposition

[0032] 1. Materials and methods:

[0033] 1.1 Insect source: Lygus stigmata bred in the best breeding conditions (25-29°C; RH: 55-65%, L:D=16:8) collected in the field.

[0034] 1.2 Method: After feeding the adult Lygus stinkbug collected in the field with rice moth eggs and tobacco leaves, put a pair of F2 first-eclosion adults into a 20*10cm transparent glass bottle, add feed, and put them into treatment 1-3 at the same time. , Then close the bottle mouth with transparent gauze and rubber bands, and change the feed and egg-laying plants every day. The replaced oviposition plants were put into glass test tubes, and the hatching situation of nymphs was observed every day, with 20 repetitions per treatment, and finally the number of adult eclosions in each group was counted.

[0035] Spawning plant treatments: See Table 1.

Abstract

The invention discloses an industrialized production method for nesidiocoris tenuis, and belongs to the technical field of biological control over agricultural pests. The method comprises the steps of legume crop cultivation, sterilization of glasshouse soil of rice moth eggs and nesidiocoris tenuis raising and collecting. According to the industrialized production method for the nesidiocoris tenuis, a series of technical problems such as plant source and animal source feed combination, plant oviposition materials and raising media are solved successfully, the problems that at present, the nesidiocoris tenuis can only be raised on a small scale in a laboratory, and the control requirements in actual production cannot be met are changed, and the industrialized production efficiency of the nesidiocoris tenuis is greatly improved. By taking the nesidiocoris tenuis as a predatory enemy to be applied to vegetables in a large area, the number of use and the use amount of insecticide can be greatly lowered, an agricultural ecological environment is protected, and the food safety is improved.

Description

technical field [0001] The invention relates to a factory production technology of a predatory natural enemy - Lygus nicotina, belonging to the technical field of biological control of agricultural pests. Background technique [0002] Greenhouse whitefly is distributed in more than 20 provinces and cities in my country. It is the main pest on vegetables in open fields and greenhouses, especially Bemisia tabaci has been rampant in recent years, seriously affecting agricultural production in our country. Whitefly (Trialeurodes vaporariorum) and whitefly (Bemisia tabaci) have a wide range of hosts and can damage more than 30 common greenhouse vegetables. Among them, bemisia tabaci is more harmful, and bemisia tabaci can also transmit viruses. At the same time, the greenhouse whitefly can also cause soot, which seriously affects the photosynthesis of plant leaves. The long-term and excessive use of conventional control chemical pesticides has caused whiteflies to develop resis...
