Problems solved by technology

However, unlike natural enemy insects that feed on leaves and stems outside the plant, Eupatoria adenophorum is a polyparasitic natural enemy, that is, each Eupatorium adenophorum can be parasitized by Eupatoria adenophorum multiple times and produce different numbers of The next generation of Eupatoria adenophorum, which brings difficulties to the quantitative evaluation of the control effect of Eupatoria adenophora, for example, the control effect on Eupatoria adenophorum plants of different growth stages and ecotypes is up to the standard when the parasitic density is how many heads, making Eupatoria adenophorum A Technical Difficulty in Practical Application Index of Flies as Biological Control Factors

[0008] 1. Establishment and propagation of greenhouse population of Bactrocera zeerifolia

[0009] (1) Preparation of Eupatorium adenophorum seedlings

[0010] According to the biological and ecological characteristics of Eupatoria adenophorum, set the main environmental conditions in the greenhouse (light about 1500Lux, temperature 15-25°C), use plastic pots (Φ100×100mm) to cultivate single-plant Eupatorium adenophorum seedlings, conventional water and fertilizer management, about After 6 months, the seedlings can be parasitized by Zeelandia fruit fly. Cultivate a batch of new seedlings every half a month to provide materials for mass rearing of Eupatoria cerevisiae and evaluation of the parasitic effects of Euperacta zeeriferae by single-plant cage method.

[0011] (2) Establishment and multiplication of the greenhouse population of E. elegans

Abstract

The invention relates to a method for evaluating a parasitic effect of procecidochares utilis on ageratina adenophora. The method comprises the following steps of: cultivating ageratina adenophora seedling and procecidochares utilis in a green house; artificially killing parasitic wasps of the procecidochares utilis; enabling the procecidochares utilis to randomly parasitize in the ageratina adenophora in the green house; selecting the parasitized ageratina adenophora, and grouping by single plant according to the parasitizing condition, wherein each group has repetition; covering each grouped ageratina adenophora plant with a transparent cover which is capable of carrying out air circulation and preventing procecidochares utilis adults from escaping, wherein a gauze element can be used as the cover; and counting the parasitizing number of the procecidochares utilis in single plant after eclosion of the procecidochares utilis adults, so that the parasitizing density and the parasitizing strength can be deduced, and the parasitic effect can be evaluated. The method can be adopted for effectively overcoming the difficulty in quantitatively evaluating the parasitic effect caused by multi-parasitism of the procecidochares utilis.

Description

technical field [0001] The invention relates to a method for evaluating the parasitic effect of polyparasitic insects on host plants, in particular to a method for evaluating the parasitic effect of Eupatoria adenophorum on Eupatoria adenophorum. Background technique [0002] Eupatorium adenophora (Ageratina adenophora Sprengel) is a vicious invasive weed. It is a perennial clustered semi-woody herb of the Asteraceae family. It is native to Mexico and is now distributed in more than 30 countries and regions in the world, and has caused severe damage in these areas. The economic loss and the "green disaster" of the ecological environment have even constituted a certain threat to the health of humans and animals. After Eupatorium adenophorum was introduced into the border of Yunnan in the 1940s in my country, it spread rapidly and is now widely distributed in Yunnan, Guizhou, Sichuan, Guangxi, Tibet and Taiwan provinces and regions, causing serious damage to local agriculture,...
