Description

Artificial feeding device for cotton bollworm adults

Technical Field

The utility model relates to an artificial feeding device for cotton bollworm adults.

Background

The cotton bollworm, also called cotton bollworm, belongs to the lepidoptera noctuidae and is an important boring pest in the cotton bud boll stage. The cotton bollworm is widely distributed around the world, is one of main pests harmful to cotton and other crops in Asia, oceania, africa and Europe, occurs in cotton areas of China and vegetable planting areas, and is seriously damaged in cotton areas of yellow river basin and Yangtze river basin. In recent years, the harm is rampant, and the occurrence frequency of the Xinjiang cotton zone is obviously increased.

The bollworm mainly eats the reproductive organs of cotton, which causes a great amount of buds, flowers and bolls to fall off and rotten the bolls, thus seriously reducing the yield and quality of the cotton. The cotton bollworm has caused serious cotton value reduction and yield reduction in China at present, the development of national economy is severely restricted, and the prevention and treatment work of the cotton bollworm is urgent. At present, the biological control method is gradually adopted by people because of high efficiency and environmental protection in the three existing physical, chemical and biological control methods for cotton bollworms. A large number of indoor tests are needed in the early stage of the biological control method, and a large amount of manpower and material resources are needed for collecting the cotton bollworm adults in the field, so that a set of system for artificially feeding the cotton bollworms needs to be explored.

In the process of artificially feeding the cotton bollworms, because the range of motion of the cotton bollworms is large, if the cotton bollworms are not limited in a certain range of motion, the cotton bollworms are likely not to be fatally fatted by food starvation, and are also likely to suffer from other external physical injuries, so that the increase of experiment cost and the waste of space resources are caused, and the subsequent experiments are influenced. Common breeding devices are mostly wooden-edge square cages, and the devices cannot meet the requirement of the cotton bollworm adults on the environment humidity; in addition, the device is inconvenient to arrange the oviposition substrate, the operation is very troublesome when the oviposition substrate is replaced every day, and the imago is easy to escape opportunistically. At present, an artificial feeding device which can be compatible with the above two problems is not found temporarily, so that a device which can meet the requirement of the device on the environment humidity and is also beneficial to the egg laying of the cotton bollworms and the collection of egg cards is necessary to be found.
