Description

Locust monitoring and trapping instrument

Technical Field

Background

Locust is an important component of the ecological system of agriculture, forestry and animal husbandry, and a great number of harmful locust species cause different degrees of harm to the agriculture, forestry and animal husbandry. There are more than 1 ten thousand kinds of locusts all over the world, and about 300 kinds of locusts which can cause harm to agriculture, forestry and animal husbandry. Over 1000 kinds of locusts are known in China, and about 60 kinds of locusts can cause harm to agriculture, forestry and animal husbandry. The adult locusts and the locust nymphs have the same feeding habits, are both phytophagous, and have strong nutrition supplement during the adult period, and the nutrition supplement accounts for more than 75% of the total feeding amount of a whole life. When the plants are bitten by a chewing mouthpart, the leaves and buds of the plants are incised and perforated, and when the plants are serious, the leaves and buds of the plants in a large area eat light, so that the great economic loss of agriculture, forestry and animal husbandry is caused. According to the long-term monitoring record of China, the locusts causing destructive disasters in agriculture are mainly migratory locusts, and have the advantages of wide distribution, high feeding impurity, high propagation speed, high stress resistance and high prevention and control difficulty.

The locust is treated by chemical pesticide, which is a main control method except for modifying the ecological environment of a locust area and reducing the reproduction land of the locust. However, with the development of society, the living standard of people is continuously improved, the ecological consciousness is continuously enhanced, the attention on self health and environmental quality is higher and higher, and the food safety problem, the environmental safety problem, the biological diversity loss, the pesticide residue and other problems caused by pesticides become the biggest threats to the survival and development of human beings at present. Meanwhile, the Ministry of agriculture proposes a 'double reduction' scheme of 'zero growth of pesticide and fertilizer' in 2015 and 2020, develops a high-efficiency safe green control technology vigorously, and is listed as a key development field of high and new technology industrialization which is developed preferentially in the current state. This provides higher requirements and challenges for sustainable management of locusts in our country.

The light induction control technology is a physical prevention and control means which promotes insects to gather at a certain fixed position to be intensively eliminated by utilizing the behavior of the insects moving towards or away from a light source, and has the advantages of high efficiency, safety, environmental protection, no residue and the like. Nowadays, the light trapping and killing technology plays an important role in pest forecasting, prevention and control of agriculture, forestry, fishing, breeding and garden landscape in China and obtains good effect. However, the proportion of the applicable light trapping technology in the locust control process is relatively small, the light trapping equipment is not reasonable in design, and the reason for this is that the locust trapping effect of the equipment is poor due to the insufficient understanding of the phototaxis behavior characteristics of the locust; the light source of the insect catching lamp has wide spectrum range, has broad-spectrum trapping and killing effect, and can trap and kill a plurality of other insects and natural enemies while trapping and killing target pests, thereby easily causing the destruction of biological diversity and natural ecological balance.

Therefore, the locust monitoring instrument suitable for various environments is designed and produced according to the spectral sensitivity difference and phototaxis characteristics and detection technical means of the locust, has the advantages of high locust capturing rate, high monitoring accuracy, cleanness, sanitation, high automation degree, simplicity in operation and maintenance and the like, and has good application effect and application prospect.
