Problems solved by technology

The mangrove ecosystem contains rich biological resources and species diversity. It not only provides a good living environment for many marine organisms, but also serves as a wintering ground and migratory transfer station for migratory birds. In addition, there are a large number of fish ponds and shrimp ponds along the mangroves. The particularity of these ecological environments requires the use of highly toxic chemical pesticides to be avoided when controlling pests; in addition, because mangroves grow in the coastal intertidal zone, control It is difficult for personnel to go deep into mangroves to carry out chemical spraying operations, which also brings new challenges to traditional pest control methods
[0004] The tung moth is one of the main pests of the mangrove plant tung tree. It mainly sticks the leaves together irregularly by spinning larvae, and potentially eats the mesophyll in the middle to harm the leaves of the tung tree, resulting in The leaves gradually wither and fall off, although the whole plant will not die, but it will seriously affect the growth, fruit and ornamental value of the tree
The predecessors have done a lot of research on the prevention and control of the small tortrix moth, but due to the particularity of the growth environment of the tung tree, it is not suitable to use chemical pesticides, it is also very difficult to operate, and the control effect is not ideal due to the influence of the tide. , in today's emphasis on protecting the environment, advocating biodiversity and ecological civilization, it is inevitable to study and use convenient and feasible biological control methods

Embodiment 1

[0028] A biological control method for the main pest of mangrove plants, Trichogramma chinensis. In the sugarcane field, use rice moth egg cards to lure Trichogramma to lay eggs in the field and return them to the room to collect Trichogramma japonica as bee species. , Insert the rice moth egg card into the bottle for collecting bee species to breed into a species breeding bee card. Be 70cm with basket body length, be wide 50cm, the plastic basket that height is 10cm raises basket as rice moth, spreads one deck feed in the basket, and used feed is the corn meal of 70% wheat bran and 30%. Sprinkle rice moth seed eggs evenly on the feed, and then cover the eggs with a layer of feed. After the eggs hatch, add appropriate amount of feed every two days depending on the food intake until the larvae pupate. The temperature in the feeding room is kept at 25-30°C. The humidity is maintained at 75%-90%. After the pupa emerges, collect the adults and place them in the egg-laying cage to...

Embodiment 2

[0031] A biological control method for the main pest of mangrove plants, Trichogramma chinensis, collects the moth eggs parasitized by Trichogramma japonica in the sugarcane field and returns them to the room to collect Trichogramma japonica as bee species. Insert the rice moth egg card into the bottle for collecting bee species and breed it into a breeding bee card. Gather fresh rice moth ovum and carry out rice moth ovum production, be 70cm with basket body, wide be 50cm, height be the plastic basket of 10cm raising basket as rice moth, spread one deck feed in the basket, used feed is 70% wheat bran and 30% cornmeal. Sprinkle rice moth seed eggs evenly on the feed, and cover the eggs with a layer of feed. After the eggs hatch, add an appropriate amount of feed every two days depending on the food intake until the larvae pupate. The temperature in the breeding room is kept at 27°C and the relative humidity is kept At 75%-80%. After the pupa emerges, collect the adults and p...

Embodiment 3

[0034] A biological control method for the main pest of mangrove plants, Trichogramma chinensis, collects the moth eggs parasitized by Trichogramma japonica in the sugarcane field and returns them to the room to collect Trichogramma japonica as bee species. Insert the rice moth egg card into the bottle for collecting bee species and breed it into a breeding bee card. Gather fresh rice moth ovum and carry out rice moth ovum production, be 70cm with basket body, wide be 50cm, height be the plastic basket of 10cm raising basket as rice moth, spread one deck feed in the basket, used feed is 70% wheat bran and 30% cornmeal. Sprinkle rice moth seed eggs evenly on the feed, and cover the eggs with a layer of feed. After the eggs hatch, add appropriate amount of feed every two days depending on the food intake until the larvae pupate. The temperature in the breeding room is kept at 30°C and the relative humidity is kept At 80%-90%. After the pupa emerges, collect the adults and plac...

Abstract

The invention discloses a method for biological control over mangrove plants primary pest Aegiceras Chaetognatha tortricidae small leaf rollers. According to the method, trichogramma chilonises are selected as bees, corcyra cephalonica eggs are adopted for carrying out trichogramma breeding in a bee breeding box, then in the middle of April of every year, the mangrove plants primary pest Aegiceras Chaetognatha tortricidae leaf rollers is controlled in the mode that two hundred thousands or more trichogramma chilonises are released per hectare every time, and thirty or more release points are arranged. The trichogramma chilonises which are the natural enemy of the woodland Chaetognatha tortricidae small leaf rollers are used for control over the mangrove plants pest Aegiceras Chaetognatha tortricidae small leaf rollers, the method is natural, free of pollution, convenient to operate and efficient and protects environment, and meanwhile the trichogramma chilonises are bred in quantity. The method for the biological control over mangrove plants primary pest Aegiceras Chaetognatha tortricidae small leaf rollers is easy to operate, environmentally friendly, free of pollution and capable of continuously controlling damage to mangrove plants aegiceras corniculatums by the Chaetognatha tortricidae small leaf rollers, and has good social benefits.

Description

technical field [0001] The invention belongs to the technical field of biological control of plant protection, and relates to a biological control method of the mangrove plant tungia toricula moth. Background technique [0002] Mangrove refers to the tidal flat wetland woody biome composed of evergreen shrubs or trees that grow in the upper part of the tropical and subtropical low-energy coastal intertidal zone and are inundated by periodic tides. It grows in tidal flats and shoals at the junction of the land and the ocean. It is a special ecosystem where the land transitions to the ocean. It is the only woody plant in the coastal wetland ecology today. It has the functions of land building, bank revetment, embankment, etc., and can effectively purify seawater. Protecting marine ecosystems and providing habitats for marine life has enormous social, ecological and economic benefits. Premier Wen Jiabao clearly pointed out the great significance of protecting mangroves when he...
