Artificial group breeding method of prodenia litura (fabricius)

Abstract

The invention discloses an artificial group breeding method of prodenia litura (fabricius). Larva and a proper number of fodder are placed in plastic boxes which are respectively 11.5cm, 13.5cm and 16.5cm in diameter and are sterilized to be bred, the plastic boxes are covered by gauzes, the box with 1 to 3 old larva is tightly covered by a lid or the mouth of the box with 4 old larva is bonded by a rubber band, the fodder and the plastic boxes are replaced every day, and after the larva pupate, pupas are picked out from the fodder and placed in the plastic boxes, and the pupas are kept wet by degreasing cotton; male and female eclosion adults are paired and placed in a glass cup to be bred, and the adults generate experimental groups under certain breeding conditions. The method is simple, convenient to perform, low in breeding cost and good in breeding effect and can perform indoor transgenerational breeding.

Description

technical field [0001] The invention relates to the breeding of agricultural vegetable pests, in particular to a group breeding method of Spodoptera litura. Background technique [0002] Prodenia litura (Fabricius) belongs to Lepidoptera (Lepidoptera), Noctuidae (Noctuidae), and is a worldwide polyphagous and migratory pest. It is mainly caused by larvae, and it enters the overeating period after 4 days of age. The damaged plants will be eaten into nicks, holes or nets in the leaves, and only the veins will be left in the severe cases. In severe cases, the stems will even be damaged, resulting in failure of harvest, and the discharge of insect feces will be polluted Melons and vegetables, insect bite wounds can easily induce soft rot, blight, viral diseases and other diseases of fruits and vegetables, seriously affecting the quality and yield of crops. In recent years, with the changes in my country's planting industry structure and climate warming, the occurrence and damag...

Problems solved by technology

The research on artificial breeding methods of Spodoptera litura, whether it is Zhu Limei et al. (2000) or Tu Yegou and Zeng Jihua (2010), Huang Yanjun and Pu Guanqin (2011) reported on artificial breeding techniques of Spodoptera litura, must use Finger tubes, insect cages or petri dishes, plastic ten-hole plates or even glass jars, jam bottles and other complicated and irregular utensils, and in the patent about raising Spodoptera litura applied by Lu Baoqian et al. (2013) also used After reaching the cell culture plate for single head feeding, the process even includes pouring the prepared feed directly into the cell culture plate to cool. waste of

[0004] Spodoptera litura has no self-mutilation habit reported, single-headed Spodoptera litura has low survival rate, heavy workload, high cost and troublesome cleaning of utensils, so group breeding is the most suitable method for raising Spodoptera litura
