Problems solved by technology

At present, there are many research reports on the application of carrier plants in greenhouse crop production to proliferate and protect natural enemies, but most of them are carrier plant systems of parasitic natural enemies
However, parasitic natural enemies are small in size and poor in adaptability to the environment, and their control effects are affected by factors such as parasitic behavior
At present, there are very few reports on the carrier plant system of predatory natural enemies, mainly because many studies are still in the experimental stage and have not been widely promoted.

[0046] Embodiment 1, seven-spot ladybug carrier plant system construction

[0047]In the greenhouse (temperature 25±1°C, humidity 65±5%, photoperiod 16L:8D, light intensity 1100lux), use the orthogonal test method to construct the seven-star ladybug carrier plant system in a plastic pot (recommended 17cm×30cm) After sowing 15-20 broad beans in the middle, conduct the test after the second day of emergence, set 4 factors and 3 levels, and clarify the key parameters: introduced ladybug density (A), inoculated aphid density (B), introduced ladybug time (C), 3 levels of time (D) for changing host plants (Table 1). A total of 9 experimental treatments (Table 2), each with 3 replicates.

[0061] Embodiment 2, application of seven-spot ladybug carrier plant system to control peach aphid effect evaluation and cost accounting

[0062] 1. The seven-spot ladybug carrier plant system controls peach aphid

[0063] Determination of the ability of the seven-spot ladybug carrier plant system to control green peach aphid in a greenhouse enclosure: set 100 mesh / cm in the greenhouse 2 There are 9 gauze covers, the cover specifications are 50cm×50cm×100cm, the cover frame material is aluminum alloy, and 6 pots of broccoli (such as image 3 ), when broccoli grows 7-8 leaves, insert 200 green peach aphids (simulated monitoring of pest populations (that is, the number of pests is greater than 10 heads / 1 square meter).

[0064] Carrier plant system treatment group: put the seven-star ladybug carrier plant system (the best combination of adult net gain) in the middle of the broccoli, specifically as follows: place the broad bean seedlings that have emerged for 2 days (central po...

Abstract

The invention discloses a method for construction and proliferating protection for a coccinella septempunctata carrier plant system. The coccinella septempunctata carrier plant system is a horsebean seedling, a substitute host is a Japanese vicia aphid, and a predatory natural enemy is coccinella septempunctata. The carrier plant system is beneficial to the proliferation and protection of naturalenemies in the early stage of occurring of pests, and effectively inhibits the pests before a large number of pests erupt, the colonization rate of natural enemy insects is increased by more than 50%compared with the direct release of ladybugs, and the method is maintained for a long time.

Description

technical field [0001] The invention relates to a method for constructing a seven-spot ladybug carrier plant system and a multiplication protection application method, belonging to the field of agricultural technology protection. Background technique [0002] Herbivorous pests (such as aphids, whiteflies, thrips, etc.) are prone to breed and break out in greenhouse crop production, which seriously affects the yield and quality of crops. These pests can not only overwinter directly in the greenhouse, but also damage crops through parthenogenetic reproduction, and some can transmit more than 200 kinds of plant viruses, causing crop diseases and reducing production. At present, chemical control is still the main method of control, but the frequent and large-scale use of chemical agents has led to a series of problems such as pest resistance, pesticide residues polluting agricultural products and the environment, seriously threatening human health and destroying the ecological b...
