Embodiment 1

[0012] A method for artificially propagating Scleroderma guanii by utilizing mature larvae of mung bean elephant as a host, mainly comprising the following steps:

[0013] Use a brush to put the mature larvae of mung bean elephant that have separated from the bean grains into a glass finger tube, so that the mature larvae of mung bean elephant are spread flat in the tube, and insert the bees of Scleroderma guanii, which are similar to the mature mung bean elephant The ratio of larvae was 1:10. Tighten the mouth of the tube with a cotton plug, label it, and place it in an incubator for cultivation. The temperature is set at 25°C and the relative humidity is 60%. The sterilization lamp is turned on for half an hour every morning and evening, and the parasitism of Scleroderma guanii is checked frequently. , cocooning, and eclosion, take out the moldy mung bean elephant mature larvae in time, add fresh mung bean elephant mature larvae, and make it lay eggs and develop into adult b...

Embodiment 2

[0015] A method for artificially propagating Scleroderma guanii by utilizing mature larvae of mung bean elephant as a host, mainly comprising the following steps:

[0016] Use a brush to put the mature larvae of mung bean elephant that have separated from the bean grains into a glass finger tube, so that the mature larvae of mung bean elephant are spread flat in the tube, and insert the bees of Scleroderma guanii, which are similar to the mature mung bean elephant The ratio of larvae was 1:20. Tighten the mouth of the tube with a cotton plug, label it, and place it in an incubator for cultivation. The temperature is set at 27°C and the relative humidity is 70%. The sterilization lamp is turned on for half an hour every morning and evening, and the parasitism of Scleroderma guanii is checked frequently. , cocooning, and eclosion, take out the moldy mung bean elephant mature larvae in time, add fresh mung bean elephant mature larvae, and make it lay eggs and develop into adult b...

Embodiment 3

[0018] A kind of method that utilizes mung bean elephant pupae as host artificially propagating Scleroderma guanii mainly comprises the following steps:

[0019] Put the mung bean chrysalis that is separated from the beans into the glass finger tube with a brush, make the mung bean chrysalis flat in the tube, and insert the scleroderma scleroderma species. The ratio of this kind of bee to the mung bean chrysalis is 1: 30. Tighten the mouth of the tube with a cotton plug, label it, and place it in an incubator for cultivation. The temperature is set at 30°C and the relative humidity is 80%. The sterilization lamp is turned on for half an hour every morning and evening, and the parasitism of Scleroderma guanii is checked frequently. , cocooning, and eclosion, take out the moldy mung bean elephant pupae in time, add fresh mung bean elephant pupae, make it lay eggs and develop into adult bees. Each mung bean elephant pupa produced an average of 2.7 bees.

Abstract

The invention provides a method for breeding bethylids by using Callosobruchus chinensis. Used substitute hosts are old and mature larvae or pupae which are separated from pisolites. The invention relates to the technical field of biological control, in particular to the method for breeding the bethylids. According to the invention, the Callosobruchus chinensis is used as an intermediate host to breed the bethylids, so that the bethylids can be industrially bred for preventing and controlling stem borers of longicorn beetles and the like, thereby being conducive to promoting the application of biological control technologies in forest protection to control the spreading of secondary pests so as to greatly reduce the use of chemical pesticides.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a method for breeding swollen bees. Background technique [0002] In urban gardens and scenic areas, many kinds of borer pests such as longhorn beetle are very serious to gardens and street trees, and are one of the destructive pests of forest trees. As an ectoparasitic wasp of the longhorn beetle, Scleroderma guanii is the main natural enemy of the above-mentioned borer pests. With the continuous expansion of pest-infested areas and areas, the technology of using Scleroderma guanides to control dry-boring pests of economic crops such as forest trees, fruit trees, and gardening has gradually received attention, and the control effect is remarkable and pollution-free. However, since the natural host of Scleroderma guanii must be collected by planing wood manually, and artificial breeding is also difficult, it is an important issue to find alternative hosts and realize ...
