A kind of indoor insect breeding device and breeding method of Thrips chrysanthemum

Abstract

The invention discloses an indoor insectary and culture method for thrips hawaiiensis. The indoor insectary for the thrips hawaiiensis comprises a cylindrical insect placing chamber and a frustum-shaped insectary. The cylindrical insect placing chamber comprises an upper-layer cover body and a lower-layer cover body. The upper-layer cover body and the lower-layer cover body are connected through a push-pull rod. Annular air holes are formed in the upper-layer cover body. A rubber ring is closely arranged in the tube wall of the insect placing chamber. The lower end of the frustum-shaped insectary is a base plate, and the upper end of the frustum-shaped insectary is the upper-layer cover body. The frustum-shaped insectary comprises a cover body connected through the push-pull rod. The cover body is arranged on the lower-layer cover body. The cover body is provided with a food tray. The food tray is contained with food needed by the thrips hawaiiensis. The cover body is provided with an oviposition tray. The oviposition tray is provided with an oviposition thin film and water. The cover body is provided with moisturizing filter paper. The invention further relates to a method of using an indoor culture pipe for the thrips hawaiiensis to culture the thrips hawaiiensis. The indoor insectary for the thrips hawaiiensis has the advantages that the structure is simple, the production is simple and convenient, a special-assigned person is not needed to guard, the culture method guarantees that the survival rate and hatching rate are high in the culturing process, the escaping quantity of the thrips hawaiiensis is reduced, and at the same time the survival rate and the oviposition quantity of the thrips hawaiiensis are improved.

Description

technical field [0001] The invention belongs to the field of agricultural methods, and in particular relates to an indoor breeding method of thrips chrysalis. Background technique [0002] Thrips hamaiiensis (Morgan) belongs to Thysanoptera Thripidae, also known as Hawaiian thrips, is an important pest that damages flower buds and young fruits of various melons, fruits and vegetables. The insect is mainly distributed in South Asia, Southeast Asia, and East Asia, and has occurred in tropical crops in Hainan, Guangdong, Guangxi, Yunnan, Taiwan, Fujian and other provinces (regions) of China, and has suffered serious outbreaks in vegetables and fruits in Hainan Province in recent years. Thrips chrysalis has more than one generation, and the generations overlap, and it can damage the young tissues of plants at any time during the year. Thrips chrysalis is harmful in the buds of plants. Once the buds of the plants are pulled out, the insects immediately gather in groups, invade t...

Problems solved by technology

The advantage of the concave slide rearing method is that this rearing method combines two concave surfaces to form a closed environment, which can prevent thrips from escaping. The disadvantage is that the space is small, and the air in the concave slide cannot circulate, which is not conducive to thrips living in it. Survival, vigor and survival rate are low. In addition, when changing food, thrips are easy to take the opportunity to escape, which is unfavorable for operation; (2) Potted plant breeding method Firstly, one end of the glass cover is tied with a layer of gauze with a rubber band, and the other end is inserted into the potted plant. The host plants of thrips were planted in the glass cover, the thrips adults were obtained in the field, and the thrips adults that needed to be raised were moved into the test tubes, and the thrips adults were raised in the glass cover

The advantage of the potted breeding method is that it is close to natural conditions, and a large number of vigorous thrips can be obtained. The disadvantage is that the thrips are easy to escape, and the eggs of the thrips are not easy to collect, which is not easy to operate. In addition, the thrips nymphs are extremely small and have overlapping generations. , it is difficult to obtain worms with the same age and high vitality for research; (3) The penicillin bottle breeding method is to spread a thin layer of cotton in a penicillin vial, cover the cotton with filter paper, add an appropriate amount of water, and tie it with a rubber band. Seal the mouth of the bottle with a layer of gauze, put thrips eggs and fresh flower buds in the vial, add appropriate amount of water on the filter paper with a syringe, put it in a porcelain plate, and raise it in an artificial climate box at 28°C, every 2-3 days replace bud

The advantage of the penicillin bottle feeding method is that it provides a large space for thrips to move, the flower buds are easy to keep fresh, and the survival rate of the thrips is high. The disadvantage is that it is not easy to operate, especially when changing food, it is easy for the thrips to escape when the gauze is opened. And the amount of insects in each bottle is very small

Thrips chrysalis is a flower-loving thrips, its growth and development need pollen, the breeding utensils in the concave glass slide feeding method and the penicillin bottle feeding method are too small, after the pollen and filter paper are put into it, there is no separation, the pollen is easy to be wet, causing thistle Horses do not feed; the potted breeding method is difficult to grasp due to the flowering period of the host plant, and the required glass cover is also large, and the yellow-breasted thrips is easy to escape or die because of its small size. Thrips are not suitable
