Method for collecting mummified aphid of aphidius gifuensis in experimental investigation

Abstract

The invention relates to the field of insect collection, and particularly relates to a method for collecting a mummified aphid of aphidius gifuensis in the experimental investigation. According to themethod, wet filter paper is placed in a disposable culture dish, a round leave with the same size with the culture dish is paved on the wet filter paper, a parasitic aphid on the age of 2 to 3, whichis parasitized by aphidius, is placed on the round leave in the disposable culture dish, a culture dish cover is covered, and a small hole with a specification of 1mm is formed on the culture dish cover so as to keep ventilation. The method disclosed by the invention is simple in operation method and is convenient for the research work of a science researcher by placing the culture dish at the room temperature or in an artificial climate box.

Description

technical field [0001] The invention relates to the field of insect collection, in particular to a method for collecting aphids of Aphids persicae in experimental research. Background technique [0002] Scholars in our country began to conduct research on Aphids persicae since the 1970s. Although the large-scale breeding of A. There is still a lot of research space and necessity. Aphid wasps are a kind of parasitic natural enemy insects that specialize in parasitic aphids. There are many kinds of Aphids wasps, important species are Aphis persica, A. Aphids, Aphids, Aphids, Aphids, etc. Among them, Aphids aphidis is a very important dominant species. Aphididae is an important parasitic natural enemy. The wasp can parasitize a variety of aphids, mainly cabbage aphid, radish aphid, tobacco aphid, etc. It is one of the important natural enemies of aphids, has important utilization value, and plays an important role in the biological control of natural enemies.

AI Technical Summary

Problems solved by technology

[0003] However, in the current research, there are deficiencies: when the aphids are parasitized by the wasps, with the growth and development of the larvae of the wasps, the internal organs of the aphids are completely eaten by the larvae of the wasps, and the aphids die; Bee larvae begin to spin silk and pupate, first bite a hole on the abdomen of the aphid, spin the silk to stick the empty shell of the aphid to the surface of the leaf or other objects and gradually form a dead aphid; the dead aphid stuck to the substrate is not easy to fall off, and the dead aphid The body is relatively soft, especially the junction between the abdomen of the aphid and the substrate is thin, and it is easy to be broken during the collection process. Once there is a breach in the abdomen, the development of the pupae in the aphid will be affected, resulting in a significant decline in eclosion rate, which will seriously Affect the accuracy of test results
