Description

Mobile diamondback moth adults electric shock killing device

technical field

The invention relates to a device for killing adults of diamondback moth by electric shock, in particular to a mobile device for killing adults of diamondback moth by electric shock. Grid electric shock hunt.

Background technique

Plutella xylostella is a worldwide pest that damages cruciferous vegetables. It damages the leaves of cruciferous vegetables, such as cabbage, cauliflower, cabbage, radish, cabbage, green vegetables, etc. The annual damage loss is more than 30%, and its adult length is 6-7 mm, with a wingspan of 12 to 16 mm. The body color of the male adult is heavier, and the forewings are mostly brown. From the base of the wing to the outer edge, there are three obvious curved ripples along the entire rear edge. When resting, the two closed wings The upper light-colored part is assembled into three oblique squares, and the trailing edge of the wings is dense and long, and each wing is in the shape of a boat. It is nocturnal, has phototaxis, and has weak flying ability. When frightened, it flies short distances between plants and can mate many times in its life. The forewings of the male moth are light grayish brown, and the distal segment of the abdomen is tubular and undivided. Eggs are oval, about 0.5 mm long, from milky white at the beginning to light yellow-green at the end. The larvae are about 10-12 mm long, light green in color, spindle-shaped, with sparse long black setae on the body surface. The pupa is about 5-8 mm long, green at first, and then grayish brown. There are cocoons, off-white, sparse and transparent. Its main habits are as follows: 1. The annual generation algebra is 3-19 generations from north to south. For example, 3-4 generations in the north, 18-19 generations will occur in Taiwan; 2. Overwintering insect state, in the north, the pupae survives the winter in the sun-lit dead leaves and weed piles, and in the south, the adults mainly hide in the fallen leaves and leaves of the stumps. Overwinter on weeds. The adults of the overwintering generation in Shandong appear in April, and the first generation of larvae appears at the end of April; 3. The adults are nocturnal, hiding in the dense branches and leaves of plants during the day, and become active near dusk to lay eggs. Most active at midnight. Adults have phototaxis, and adults live longer. The oviposition period is long and uneven, so the generation overlap phenomenon is serious; 4, oviposition habit, a female generally lays about 200 eggs, mostly in the depression between the leaf veins on the back of the leaf, single scattered eggs and 3 ～5 small egg masses basically account for half each; 5. Each ecological period, the egg period is about 5 days, the larvae have a total of 4 instars, about 12-27 days, and the pupae period is 8-14 days; 6. Larval habits, more after maturity Cocooning and pupating on the back of leaves or fallen leaves. When the larvae are disturbed, they will violently twist and retreat or spin silk drooping; 7. The environment for occurrence, the optimum temperature for development is 20-30°C, when the weather is warm and there is little rain Serious damage. The occurrence is heavier in spring in the north, and the spring and autumn in other areas are heavier than summer.

The current traditional micro-pollution and pollution-free control techniques: 1. Agricultural control, including timely removal of weeds and litter to eliminate overwintering pupae and mature larvae. Reasonably arrange vegetable crops to avoid planting cruciferous vegetables in a small area year after year; 2. Biological control. The natural enemies of diamondback moths mainly include spiders, lacewings, frogs, and parasitic diamondback moth seedling wasps and diamondback moth gnats. wait. In addition, granulose virus has a certain control effect on the population of diamondback moth. In the application of microbial pesticides, you can choose 1000 times liquid of BT emulsion or bacteria powder of Cerocidal bacteria, or HD-1 bacteria powder, or 500-1000 times liquid spray of 7216 bacteria powder with a spore content of 10 billion/g, after 7 days Spray it again. In order to improve the adhesion rate of biological bacteria powder, 0.1% washing powder can be evenly mixed into the bacteria solution; 3. Trapping, using the phototaxis habit of diamondback moth, trap adults with black light or other light sources at 7-11 in the evening , the time is mainly arranged in April-May and August-September; 4. The use of sex attractants. In recent years, there are two methods of successful experiments and set-up points of application. One is to put 1 to 2 female moths into 60 In the purpose gauze net, a potion pot is set under the net to lure the males to hunt and kill. According to the experiment, 220-500 males can be lured at one time. The second is to cut off the rear end of the abdomen of the female moth, extract the sex inducer with an organic solvent such as benzene or methylene chloride, and spray or drop it on a small paper tube made of absorbent paper (a small paper tube uses a 5 x 5 cm square. Paper rolls), hang the paper slips with wire and hang them 1 cm above the wooden basin with washing powder or odorless pesticides, hang them in the field every evening, and take them back in the morning. The one-time lure extract can generally be used for 7 to 10 days , in a radius of 100 meters, it can trap nearly a thousand male moths at most in one night; 1000-1500 times liquid. Spray control before the 2nd instar larvae.

Although the various traditional methods mentioned above can achieve a certain effect to a certain extent or in combination, they may also cause another biological hazard risk due to the shortcomings of their respective prevention and control, such as biological control, which are difficult to implement and control. The use of traps and sex lures is limited by their radiation range and requires a lot of tools and manpower input, making it difficult to popularize and apply. Chemical control is the most basic method at present, but due to the many generations of Plutella xylostella in my country, the serious overlapping of generations, and the inconsistency of field larval ages, the Plutella xylostella has developed extremely high resistance to pyrethroid pesticide control after long-term use of pesticides. The control effect of pyrethroid pesticides is extremely poor, and high resistance to organophosphorus and carbamate pesticides has been produced, and the control effect of single agent in the field is not ideal. Although high-efficiency, low-toxicity, and low-residue compound preparations have good effects, their prices are relatively expensive, which greatly increases the cost of prevention and control.
