Embodiment 1

[0016] A method for artificially breeding Dagu wax nails, comprising the steps of:

[0017] (1) Breeding conditions: room temperature is 20±2°C, humidity is 70±5%;

[0018] (2) Breeding of adults: place 2 / 3 of the sawdust in a circular culture box, mix the sawdust with distilled water, and the humidity is such that no water droplets can be squeezed out by hand; place mung beans parasitized with corn elephants in the sawdust, including at least 10- 15 large corn elephant larvae or 20-30 small corn elephant larvae, then place 10 large larvae male adults and 10 large larvae female adults, then cover the box and put it in a dark place; the adults will take Feeds on corn weevil larvae and lays eggs;

[0019] (3) Raising of larvae: After the eggs hatch into small larvae, let them eat corn weevil larvae in the culture box until the 2nd instar, then remove it and place it in a rectangular box with sawdust to feed it with corn weevil larvae Feed; the height of the sawdust is 8mm from...

Abstract

The invention relates to application of sitophilus zeamais larvas as living feeds in artificial breeding of rhizophagus grandis. The reproductive capacity of the sitophilus zeamais is high (eleven-generation breeding can be performed in proper environment in one year), the feeding sources (mung beans, adzuki beans, cowpeas and the like) are wide and are low in price, the breeding technology is easy to operate, the sitophilus zeamais is used as living feeds for the large-scale propagation of the rhizophagus grandiss, and the obtaining is simple and convenient. The manual large-scale breeding of the rhizophagus grandis can be realized. The application has the purpose of treating Dendroctonus valens Leconte insect damage.

Description

technical field [0001] The invention relates to the field of insect breeding, in particular to the technology of artificial propagation of the wax beetle. Background technique [0002] The red beetle, also known as the mighty beetle, is an exotic forestry pest from North America. It was first discovered in Qinshui County and Yangcheng County of Shanxi Province in my country in 1998, and it is a newly recorded species in China. The insect mainly harms the main trunk and main lateral roots of pine trees with a diameter above 10 cm, as well as the felling piles and logs of fresh Chinese pine. Feed on phloem and cambium with adults or larvae. When the insect population density is high and the damaged parts are connected to form girdling, the whole tree may die. At the end of 1999, the pest occurred in Shanxi, Hebei, and Henan provinces on a large scale. In 2001, the pest was also found in Shaanxi Province. By the end of 2004, the total occurrence area of ​​the country was 162...
