Embodiment 1

[0018] During the cultivation of muskmelons in greenhouses, greenhouse whiteflies often occur in large areas. The adults and nymphs of this kind of pests suck the plant juice, and the leaves after the damage turn yellow, wilt, and die. The range of damage is large, and the damage is caused by clusters. During the damage process, a large amount of honeydew is secreted, which pollutes the leaves and fruits, often causes the occurrence of coal pollution, and reduces the commodity value of melons.

[0019] The experiment was carried out in the greenhouse at the base of Shandong Shouguang Vegetable Industry Group Co., Ltd. in 2017. Celery was planted in the last crop and tomatoes were planted in the current season.

[0020] Lithias bee card (provided by Shandong Lubao Science and Technology Development Co., Ltd.), released to the field after 2-3 days to produce bees.

[0021] A 60-mesh insect-proof net was used for the netting test, and the greenhouse was normally ventilated. The e...

Embodiment 2

[0030] This experiment was carried out in the Tai'an Greenhouse Experimental Area in Shandong Province from May to July 2018, and the eggplant variety was Pingqi No. 1.

[0031] A 60-mesh insect-proof net was used for the net test. The greenhouse was normally ventilated. The entire greenhouse was divided into areas A, B, and C with the same conditions by nylon wire mesh. Corresponding control experiments were carried out. During the release period, no chemical pesticides.

[0032] Among them, the A and B areas were put into the East Asian flower stinkbug, and the C area was used as a blank control. In Zone A and Zone B, when the eggplant grows to 5-7 leaves in the greenhouse, it starts to release the stinkbug (starvation for 1 day before release), the release density is 500 heads / mu, and the frequency is 3 times, and the interval between each feeding is 7 days. Place a sufficient amount of 5% honey water in area A, and place a sufficient amount of 5% honey + egg white liquid ...

Embodiment 3

[0040] This experiment was carried out in an organic vegetable base in Persimmon Garden, Licheng District, Jinan City, Shandong Province from September to December 2016. The cucumber variety was Jinyou 1. The test sheds are about 1 mu each, one is a treatment shed and the other is a control shed; before planting, a 60-mesh insect-proof net is installed at the vents of the shed.

[0041] Treatment shed: (1) Lepidos wasps: hang Lemons bee cards directly on the middle and upper branches of the plants, and release them once on October 9, October 19, and November 15, 3000 each time; (2) East Asian flower bug: release once on October 9 and November 15, 300 each time. Place a sufficient amount of 5% honey + egg white liquid (mass ratio 1:1) in the shed.

[0042] After the release, 10 plants were selected in each shed for investigation, and the survey was conducted every 7 days, and the number of whiteflies and thrips on each plant was recorded respectively.

Abstract

The invention belongs to the technical field of biological prevention and control of crop pests, and particularly relates to a biological prevention and control method for main pests of vegetables ina facility. According to the biological prevention and control method for the main pests of the vegetables in the facility, natural enemy insects of the pests are put into the facility in a targeted mode according to the types of the main pests existing in crops planted in the facility, so that the purpose of preventing and controlling the pests is achieved through the predation or parasitic effect of the natural enemy insects, and the problem of influence on crop pollination due to pesticide spraying in the facility is effectively avoided. According to the biological prevention and control method, the natural enemy insects which are most suitable for being put are screened out for different harmful insects according to early experience, and growth of the crops in the facility is powerfully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of biological control of crop pests, and in particular relates to a biological control method for main vegetable pests in a facility. Background technique [0002] Facility vegetables are an important part of modern agriculture, and my country is the largest facility vegetable growing country in the world. The development of facility vegetables has led to a rapid increase in the variety and output of vegetable production, which has brought huge economic benefits. However, the special facility planting conditions provide pests with an ecological environment suitable for growth, reproduction and harm, resulting in rampant occurrence of aphids, whiteflies, thrips, spider mites and other pests. The vegetable virus diseases transmitted by lice and aphids caused huge economic losses and seriously affected the safety of vegetable production. At present, the pest control in the production of protected vegetables i...
