A group feeding method for feeding Spodoptera frugiperda larvae with corn shoots

Abstract

The invention discloses a group feeding method for feeding Spodoptera frugiperda larvae with corn shoots. It mainly spreads fine sand on the bottom of the feeding box, and uses different tissue parts of corn shoots, such as corn shoot bracts, corn cobs and corn shoots. Bamboo shoots, etc. are used as food, and are placed at intervals on the surface of the sand layer to form a multi-layer stacked structure, which is used to feed the larvae of Spodoptera frugiperda, and sieve the pupae from the sand and collect eggs from adults to complete the growth of Spodoptera frugiperda. Its operation process is simple, safe and reliable. It makes full use of the characteristics of different components of corn shoots as food, and builds surface accumulation in the narrow breeding box to form a wide stacking structure, effectively isolating the larvae of fall armyworm. The use of sand to dry the internal environment of the breeding box and burial to form a suitable humidity is conducive to the function of pupation of Spodoptera frugiperda. Mature larvae pupate in the sand to facilitate the collection of pupae in the later stage, forming a group Feeding method, and save labor.

Description

technical field [0001] The invention belongs to the field of agricultural and forestry biotechnology, and relates to a method for artificially raising Spodoptera frugiperda, in particular to a method for feeding Spodoptera frugiperda larvae with corn shoots for group rearing. Background technique [0002] Corn is a gramineous crop, an annual herb plant, and is the food resource that human beings rely on for survival. It is also an important cereal crop in my country, and its total output ranks second only to rice. In recent years, corn has developed into an important food, feed and industrial raw material crop in China. The development scale of corn production has become an important factor affecting the supply and demand of my country's grain, determining the development of animal husbandry and corn processing industry, and an important part of national food security. Spodoptera frugiperda, commonly known as Fall armyworm (Fall armyworm), belongs to the Lepidoptera Noctuid...

Problems solved by technology

[0004] With the continuous deepening of scientific research on fall armyworm and the development of control technology, a large number of insect sources with uniform development and uniform physiology are needed, which are limited by seasons and the growth cycle of host plants, especially when the larvae of fall armyworm are at a higher density. , the larvae often kill each other, or the larvae bite the pupa, and the method of feeding a single larva is time-consuming and laborious, and also wastes the remaining food. Therefore, there is an urgent need for an optimized feeding method and process for group feeding of Spodoptera frugiperda Larvae provide a large number of physiologically uniform insect sources for future scientific research on the biology, ecology, and physiology of Spodoptera frugiperda and the expansion of natural enemy parasitoids
