DorysthenesgranulosusThomson indoor artificial breeding method

Abstract

The invention provides a DorysthenesgranulosusThomson indoor artificial breeding method comprising the following steps: collecting DorysthenesgranulosusThomson imago; making the DorysthenesgranulosusThomson imago to mate and lay eggs, and collecting and hatching DorysthenesgranulosusThomson eggs so as to obtain primary hatching larva; arranging culture holes on an end face of a fresh sugarcane stem, and inoculating the primary hatching larva into the culture holes for cultivation; transferring the larva into sugarcane stems for single breeding when the larva appetite largely grows; respectively placing pupa into an eclosion container for single eclosion after mature larva creep into soil and pupate; placing male/female mixed eclosion imago into an insect culture container for mating after DorysthenesgranulosusThomson eclosion, and paving a 1-3cm thickness fine sands on the bottom of the insect culture container so as to allow the DorysthenesgranulosusThomson to lay eggs. By using the method, the DorysthenesgranulosusThomson is high in egg hatching rate, high in larva survival rate, high oviposition amount, thus contentiously obtaining large amount fully grown individuals, and providing important base for DorysthenesgranulosusThomson control research.

Description

technical field [0001] The invention belongs to the technical field of insect feeding, and in particular relates to an indoor artificial feeding method of the cane root beetle. Background technique [0002] Dorysthenes granulosus Thomson, 1860, belongs to Coleoptera, Cerambycidae, Prioninae, Dorysthenes, also known as cane root saw beetle or cane root Longhorn. It is one of the main underground pest species in sugarcane areas in my country. Cane root beetle is mainly distributed in Guangxi, Guangdong, Yunnan, Hunan, Hainan, Zhejiang, Fujian, Hong Kong, Guizhou and other places in China; it is distributed in Vietnam, Myanmar, Thailand, India, Laos, Cambodia and other countries abroad. Hosts include sugar cane, longan, citrus, eucalyptus, cassava, chestnut, pine, oil palm, coconut, betel nut, rubber, pachyderm, oak, bamboo, etc. [0003] In the past, the insect generally only occurred sporadically in individual sugarcane areas, and no serious damage was seen. However, in re...

AI Technical Summary

Problems solved by technology

Artificial feed can sustainably obtain a large number of well-developed insects with consistent physiological indicators, but there is no artificial feed for cane root beetle at present, and the outdoor field breeding method needs to plant sugarcane, requires a considerable area of ​​experimental land, and the field is affected by the natural environment Larger, the growth of the cane root soil beetle is irregular and the survival rate cannot be guaranteed

At present, the experimental insect sources can only be collected by cutting and digging cane stalks in the field, which is time-consuming and laborious, and it is difficult to obtain a large number of individuals with neat development and consistent physiological indicators.
