Embodiment 1

[0029]The annual industrialized breeding method of Lepidos wasps described in this embodiment uses tobacco as a host plant and whitefly in a greenhouse as an intermediate host to breed Lepidos wasps, specifically comprising the following steps:

[0030] (1) Mix peat soil, perlite, vermiculite, compound fertilizer and organic fertilizer according to the volume ratio of 8:4:2:2:0.5 as potting soil, and select tobacco as the host of whitefly in the greenhouse for potting cultivation ; Grow seedlings with seedling trays, move them into small pots when they grow to the small cross stage, move them into middle pots during the big cross stage, and move them into large pots when they have 5 true leaves;

[0031] Described compound fertilizer is the compound fertilizer of conventional nitrogen, phosphorus, potassium, and in described compound fertilizer, total nutrient (N+P 2 o 5 +K 2 O) content is about 45%, and the N, P 2 o 5 、K 2 O content is 15%, 15%, 15%, and described organi...

Embodiment 2

[0037] The annual industrialized breeding method of Lepidos wasps described in this embodiment uses tobacco as a host plant and whitefly in a greenhouse as an intermediate host to breed Lepidos wasps, specifically comprising the following steps:

[0038] (1) According to the volume ratio of 10:2:4:0.5:2, peat soil, perlite, vermiculite, compound fertilizer and organic fertilizer are mixed as potting soil, and tobacco is selected as the host of whitefly in greenhouse for potting cultivation ; Grow seedlings with seedling trays, move them into small pots when they grow to the small cross stage, move them into middle pots during the big cross stage, and move them into large pots when they have 5 true leaves;

[0039] After the tobacco seedlings are transplanted into small pots, take 50 pots of tobacco seedlings, and start to pour nutrient solution in the tobacco pots after 7 days after the tobacco seedlings are transplanted, once a week, 100ml per pot, until whitefly can be bred, ...

Embodiment 3

[0044] The annual industrialized breeding method of Lepidos wasps described in this embodiment uses tobacco as a host plant and whitefly in a greenhouse as an intermediate host to breed Lepidos wasps, specifically comprising the following steps:

[0045] (1) Mix peat soil, perlite, vermiculite, compound fertilizer and organic fertilizer according to the volume ratio of 9:3:3:1:1 as potting soil, and select tobacco as the host of whitefly in the greenhouse for potting cultivation ; Grow seedlings with seedling trays, move them into small pots when they grow to the small cross stage, move them into middle pots during the big cross stage, and move them into large pots when they have 5 true leaves;

[0046] After the tobacco seedlings are transplanted into small pots, take 50 pots of tobacco seedlings, and start to pour nutrient solution in the tobacco pots after 7 days after the tobacco seedlings are transplanted, once a week, 100ml per pot, until whitefly can be bred, so that the...

Abstract

The invention belongs to the technical field of biological prevention and control of agriculture and forestry injurious insects, and particularly relates to a method for improving factory propagation efficiency of encarsia formosa. According to the anniversary factory propagation method of encarsia formosa disclosed by the invention, compound fertilizers and organic fertilizers are applied in earlier stages for mixed applying cultivation, and nutrient solution cultivation is carried out in later period, so that the cultivation quality of tobacco seedlings is obviously improved, the effects that the tobacco seedlings are strong and leaves are large and green are achieved, and thus improving the propagation efficiency of trialeurodes vaporariorum and encarsia formosa in green houses.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and in particular relates to a method for annual factory breeding of Lime aphid wasps. Background technique [0002] Bemisia tabaci and greenhouse whitefly belong to Homoptera (Ho-moptera) and whitefly family (Aleyrodidae), both of which are important pests that endanger agricultural and forestry crops worldwide. With the occurrence of agricultural and forestry crops, it can damage more than 20 economic crops such as tomato, cucumber, cabbage, cauliflower and flowers such as poinsettia and okra. [0003] Both whitefly and greenhouse whitefly have file-sucking mouthparts. Adults and nymphs suck plant juice, secrete a large amount of honey during the damage process, induce and spread a variety of mold diseases, have a wide range of hosts, and harm flowers, fruit trees, medicinal materials, tobacco, etc. There are more than 600 kinds of plants in more t...
