Problems solved by technology

The most critical technology for the control of Beauveria bassiana is to screen highly virulent strains, but the screening of highly virulent strains requires a large number of live larvae of different ages for indoor virulence testing, so finding a simple, time-saving and labor-saving method The method of live capture of eucalyptus bat moth larvae in the wild is very necessary
Because eucalyptus bat moth larvae use boreholes as a means of avoiding natural enemies, they spend all their larval stages in the borehole and will not easily leave the borehole. Therefore, it is very difficult to capture live larvae. At present, there is no other way than to split the borehole and take out live insects. In addition, there are no patents and literature reports on other live larva capture methods

Embodiment 1

[0017] Tear open the eucalyptus bat moth bag in half, find the mouth of the moth, use tweezers to clean up the sawdust and worms around the mouth of the moth, wash the bottle with a 500ml capacity of 1:1 pepper water, and pour the pepper water into the eucalyptus bat In the moth-eaten path, fill the moth path with chili water, cover the worm bag back, keep quiet and wait for 2 minutes, when there is movement in the worm bag, immediately remove the worm bag, quickly clamp the larvae from the head and neck with tweezers, and put Larvae are removed from the borer tunnel and brought back to the chamber in centrifuge tubes.

[0018] The configuration method of the above-mentioned 1:1 chili water is as follows: weigh a certain amount of fresh chili, put it into a blender, add distilled water equal to the weight of fresh chili, stir and pulverize it, filter it with medical gauze to remove the chili residue, and obtain the required chilli water.

Abstract

The invention provides an alive endoclyta signifer larva field capture method. The method includes opening a frass block, finding a gallery port, removing wood bits and threads surrounding the boring channel port through tweezers, injecting pepper liquid with the weight and concentration ratio of 1:1 into a plastic container with a long mouth to inject into the endoclyta signifer larva gallery fully, recovering the frass block, stimulating and forcing the larva to crawl from the port, catching the larva alive through a tool after the larva crawls from the port, placing the larva into a finger-type plastic container, and carrying back to a chamber standby. The method has the advantages that time and force are saved, the time for catching one larva is shorter than 5 minutes averagely, pepper serves as raw material, cost is low, and the pepper liquid preparation is easy and simple; the method is adaptive to capturing large amount of alive endoclyta signifer larvae of different ages in the field, large amount of experiment materials are provided for screening highly virulent Beauveria bassiana strains of endoclyta signifer, and the purpose of controlling the endoclyta signifer constantly can be achieved.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural and forestry pests, and relates to a method for catching live eucalyptus moth larvae in the field. Background technique [0002] Eucalyptus bat moth ( Endoclyla signifier Walker) is a main stem-boring pest that has harmed the trunk energy of eucalyptus, the main timber species in southern my country in recent years. If it grows normally, it will easily lead to windbreak or dead eucalyptus in severe cases, causing great economic losses. At present, the control method of this insect is mainly based on chemical control. Chemical control should not be used too much due to factors such as negative impact on the environment and damage to natural enemies. Effective biological control technology needs to be developed to control this insect. [0003] Regarding the biological control technology of this insect, according to Yang Xiuhao’s report, (Study on the bioecological charact...
