Problems solved by technology

[0003] The purpose of the present invention is to disclose the method for the propagation of Aphids persicae by pea aphids, so as to solve the problems in the prior art that the cost of breeding C. persicae with A. Aphids aphids is used to prevent and control tobacco aphids that endanger the healthy growth of tobacco leaves, avoid or reduce the pesticide pollution caused by the use of chemical pesticides to kill insects

Embodiment Construction

[0014] A method of using pea aphids instead of aphids to reproduce Aphids persicae on a large scale, mainly aimed at the current existence of using flue-cured tobacco and aphids to propagate Aphids persicae: when the dead aphids are scattered, it is easy to cause artificial transmission of aphids and tobacco virus diseases, It is researched on issues such as low efficiency of breeding bees and high cost of breeding bees. The main difference between this method of multiplying bees and other methods of multiplying bees is that aphids are not passed on. Its main features are as follows: First, the pea aphid does not harm flue-cured tobacco and does not transmit tobacco virus disease; the host plant for breeding the pea aphid does not transmit tobacco virus disease. The second is that the bee breeding cycle is short, about 2 months, and the nursery pool vacated after the flue-cured tobacco is transplanted can be used to raise seedlings and bees; the third is that the bee breeding ...

Abstract

The invention provides a method for propagating Aphidius gifuensis by pea aphids. The method provided by the invention utilizes two facilities including a seedling culture big shed and a field small shed and takes broad beans and peas as host plants for propagating aphids; the method takes the pea aphids as host aphids for propagating Aphidius gifuensis and then the propagated Aphidius gifuensis are released to a large-scale tobacco field to kill the aphids on tobacco leaves. The method selects the broad bean seeds and the pea seeds and then tender green bean plants are cultivated in a big greenhouse or the small shed built in the fields; the pea aphids are inoculated on the bean plants and then the pea aphids are propagated; then the Aphidius gifuensis is inoculated on the tender bean plants which is propagated with a lot of pea aphids and then the Aphidius gifuensis is propagated. Then a lot of propagated Aphidius gifuensis are released into the large-scale tobacco field to kill the aphids on tobacco leaves. Finally, the aim of biologically preventing and treating aphids is realized and the pesticide pollution caused by preventing the aphids is avoided.

Description

technical field [0001] The invention relates to a method for breeding Aphids aphids by pea aphids, belongs to the technical field of biological control of agricultural pests, and is suitable for preventing and controlling aphids in tobacco fields and aphids in large agricultural crops. Background technique [0002] In the popularization and application of the technology of preventing and controlling Aphids persicae, it was found that using roasted Aphids persica to reproduce A.sia persicae, when spreading dead aphids, it is easy to cause artificial transmission of persimmons and tobacco virus diseases, and the efficiency of breeding C. The high cost of Aphidia persicae is an urgent problem to be solved in the popularization and application of the current technology of controlling Aphisia persicae. In the current literature, there is no report on the parasitism of Aphidida persicae and the reproduction of Aphidia persicae by the persimmonia persicae. The research found that ...
