Problems solved by technology

The parasitic rate measuring device of this invention, because the parasitic wasp and the host insect are placed in the same container, it is not convenient for the feeding of the parasitic wasp and the host and the cleaning of the living environment, and it is difficult to manage and control. However, the test cycle is long, time-consuming and labor-intensive, and more importantly, the existing detection devices cannot comprehensively and effectively evaluate the parasitic ability of parasitic wasps

Embodiment 1

[0044] Such as figure 2 It shows a device for detecting the parasitic ability of parasitic wasps, which device includes: a parasitic bee box body 1 and a host box body 2 connected in combination; the parasitic bee box body 1 is cylindrical and used for Breeding and rearing; the bottom plate of the parasitic bee box 1 is detachable, so as to facilitate connection with the host box 2; the top of the parasitic bee box 1 is provided with a ventilation hole 3 and a feed hole 4, wherein the ventilation hole 3 is used to ensure that the parasitic bee box body ventilation, on the other hand, A. cotton bollworm can be introduced into the parasitic bee hive 1 by ventilation hole 3; ; The host box 2 is a round platform, which is used for feeding the armyworm after laying eggs by A. dentata. At least one panel of the host box 2 is provided with ventilation holes to ensure that the armyworm grows in the box. Oxygen requirements; the top plate of the host box 2 is detachable, so as to fac...

Embodiment 2

[0057] To evaluate the cotton bollworm ( Campoletis chlorideae ) in armyworm ( Mythimna separata ) as an example, using the parasitic ability detection device designed in Example 1, the inventors conducted a further evaluation. The specific process is briefly introduced as follows. The parasitic hive is figure 2 As shown in 1, the host box is figure 2 Shown in 2.

[0058] Compared with the method for evaluating the parasitic ability of parasitic wasps in embodiment 1, the present embodiment is adjusted as follows:

[0059] Step (1) There are 1 female bee and 1 drone in the parasitic bee box, free mating for 2 days, put 10 third-instar armyworm larvae into the host box, and feed for about 2 hours to adapt to the environment; Step (2) Parasitism The time is 1 hour, and the parasitic operation starts at 8 o'clock in the morning; step (3) after separating the parasitic bee box from the host box, continue to cultivate the armyworm in the host box for about 1 hour; Step (2...

Embodiment 3

[0061] The parasitic hive is figure 2 As shown in 1, the host box is figure 2 Shown in 2.

[0062] Compared with the evaluation method of embodiment 1, the present embodiment is adjusted as follows:

[0063] Step (1) There are 5 female bees and 10 male bees in the parasitic bee box, free mating for 1 day, and then take 1 female bee and put it in the parasitic bee box; put 60 first-instar armyworm larvae into the host box, feed Feed for about 4 hours to adapt to the environment; Step (2) The parasitic time is 4 hours, and the parasitic operation starts at 10 am; Step (3) After separating the parasitic bee box from the host box, continue to cultivate the armyworm in the host box About 1 hour; the Helicoverpa armigera was parasitized continuously for 3 days by repeating the above steps (2) and (3).

[0064] Conditions such as the proportion of female bees and drones used, free mating time, etc. are subject to the conditions of Example 1, and the effects of the proportion of ...

Abstract

The invention belongs to the technical field of biology, and particularly relates to a device for detecting the parasitic ability of parasitic wasps and a method for evaluating the parasitic ability.The device for detecting the parasitic ability of the parasitic wasps comprises a parasitic wasp hive and a host tank. The parasitic wasp hive and the host tank are combined and connected with each other; a ventilation hole and a feed hole are formed in the top of the parasitic wasp hive; the host tank is matched with the parasitic wasp hive, face plates on at least one surface of the host tank are ventilated, and a top plate of the host tank can be detached. The device for detecting the parasitic ability of the parasitic wasps and the method for evaluating the parasitic ability have the advantages that the combined device is convenient to assemble, detach and operate, simple in structure and low in manufacturing cost; the device is applicable to detecting the parasitic ability and parasitic effects of diversified parasitic wasps and is high in applicability; the method for evaluating the parasitic ability of the parasitic wasps can be implemented by the aid of the device, the parasitic ability of the parasitic wasps can be quickly and accurately tested by the aid of the method, accordingly, bases and technical support can be provided to realizing pest control effects by the aid ofthe parasitic wasps, and the technical problem of difficulty in monitoring and detecting the wasp breeding quality can be solved by the aid of the device and the method.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a device for detecting the parasitic ability of parasitic wasps and a method for evaluating the parasitic ability. Background technique [0002] Parasitic wasps account for 20% to 25% of insect species and are the most abundant and most evolved group of animals on earth. Parasitic wasps are the natural enemies of many agricultural and forestry pests and the main force to ensure the safe production of crops. Green control measures using parasitoids to control pests have become an important part of agricultural and forestry pest control. Many important natural enemy insects have achieved large-scale production and commercialization in western developed countries. Only the natural enemy insect products produced by the Dutch company KOPPERT have occupied most of the European market and are widely used in farmland, orchards, greenhouses and horticultural crops. In co...
