The main living habits are divided into feeding habits, addiction, suspended animation and clustering:
1, feeding habits. Insects are very strict about their food choices. According to statistics, about 48.2% of all insects eat plants; About 17.3% ate decayed matter; Parasitic insects account for 2.4%; Predators account for 28%; Everything else is omnivorous.
According to the nature that insects feed on food, insects can be divided into: ① phytophagy. Feeding on living plants, flower pests are mostly phytophagous. Such as aphids, borers, cutworms, etc. ② saprophytic. Pests that feed on decaying plants and animals, such as some flies and some beetle larvae. 3 eating meat. All natural enemies of insects that feed on living animals are carnivorous, such as ladybugs, lacewings and parasitic bees.
According to the number of plant species that herbivorous insects choose to feed on, they can be divided into three types: monophagia, oligophagia and polyphagia: ① monophagia. This insect only feeds on one plant, such as the pear stem bee, which only harms pear trees; Citrus peeler only hurts citrus. 2 lack of food. It can eat a variety of plants in a family or related families, such as leaf roller moth, which can harm a variety of flowers and trees in Rosaceae. 3 eat more. Can eat plants of different families, such as cotton aphid, gypsy moth, peach moth, flies and so on. Cotton aphid can harm 285 species of plants in 74 families.
2. tropism. Insects tend to or deviate from the stimulation of external light, heat and chemicals, which is called tropism. According to the types and properties of irritants, trends can be divided into phototaxis, chemotaxis, thermotropism, hydrotropism, tactile sensation and acoustic orientation. The phototaxis and chemotaxis are the most important. ① phototaxis. Many insects have certain phototaxis, which is produced by the stimulation of light source by visual organs. For example, many moths, beetles and crickets have the habit of phototaxis. Different kinds of pests prefer different light, for example, corn borer prefers fluorescent lamp; Gryllotalpa, Noctuidae, etc. There is a strong tendency to black light. ② Chemotaxis. Chemotaxis is caused by the stimulation of chemicals by insects through olfactory organs (antennae). Using this characteristic of insects, we can control some pests, such as killing adult cutworms with acetic acid, killing crickets with fried bran, killing Noctuidae pests with sweet and sour liquid or poplar branches, etc.
3. Feign death. Some pests will temporarily stop their activities or fall down automatically when they are disturbed by the outside world, just like they are dead. This is called suspended animation. For example, scarabs, scarabs, some weevils, black cutworms and larvae of armyworms. , suddenly fell into a paralytic coma, then suddenly shook, pretending to be dead. You can use their fake death to kill people.
4. Clustering. Some pests are clustered, especially the larvae after hatching often live together, such as the larvae of the boat caterpillar often cluster together to do harm; Young awning caterpillars weave nets among branches and cluster in the nets; Before the corn tassels, the jade moths gathered in the heart leave for harm; Twenty-eight ladybugs live together for the winter and so on. If you want to kill cockroaches and mice, you need to find a military friend pest control company. -4007
