The Chinese prickly blind bug is a genus of micro-prickly bratisses in the family Hemiptera, and was once considered a pest of mangoes. With the study found that the Chinese micro-spiny blind bug can prey on a variety of fruit tree and vegetable pests, the amount of predation is large, is an important natural enemy of crop pests such as eggplant, cucumber, melon, beans, soybeans, longan and other crop pests, and can feed on thrips, aphids, mites, whiteflies and eggs of some insects on these plants.
Antennae play an important role in the chinese micro-prickly blind bug in the search for plant hosts, feeding, foraging, migration and other behaviors. There are more hair-shaped sensors and spiny sensors on the antennae of the Chinese micro-prickly bug, and the hair-shaped sensors have been found to have functions such as touch, smell, taste, and mechanical sensation, and the thorn-shaped sensors mainly have various functions such as mechanical sensation.
The Chinese prickly blind bug is widely distributed in 36 species in 12 families, including fruit trees, vegetables, ornamental plants, etc., and is mainly active on the flowers, caps or leaves of these plants. The wild plant hosts of the Chinese prickly prickly blind bug are also very rich, with the largest variety of weeds in the Asteraceae family. Some wild plants, such as the cracked fruit of the Xiao Brahma flower, are a good place for the Chinese micro-prickly blind bug to shelter from the cold.
The chinese micro-prickly blind bug hosts found have the following commonalities:
1. There are arthropod food materials for them to feed;
2. There are closed leaves, dense villi or dense inflorescences for its habitat, because the blind bugs have negative phototropism;
3. Volatile odor of leaves or flowers, such as lantana, yellow locust, etc., have special odors;
4. There are branches, petioles, veins or flower stalks suitable for laying eggs.
Researchers in an ecological village farm in China, at the same time cultivated two pieces of eggplant land as a test site, one piece of land released Chinese micro-prickly blind bugs, and one piece of land under natural conditions into the natural conditions of natural enemies. The results of the experiment showed that the number of thrips releasing the Chinese micro-prickly brachycephalus test site was almost linearly reduced. It can be seen that the Chinese micro-spiny blind bug has a strong predatory effect on pests and is an insect with broad application prospects.
