Method for pollinating early spring crops by domesticating insects at low temperature

Abstract

The invention discloses a method for pollinating early spring crops by domesticating insects at low temperature. The method comprises the following steps: after adult chrysomyia megacephala is sexually mature and copulates, laying eggs, hatching the eggs into larvae, putting the newly hatched larvae of the chrysomyia megacephala into a climate box for raising in a low-temperature domestication environment, keeping the temperature of the climate box at 15-25 DEG C, and raising the newly hatched larvae of the chrysomyia megacephala in the climate box until the newly hatched larvae of the chrysomyia megacephala are initial eclosion adults; and dividing a greenhouse into multiple ridges, planting oilseed rape male parents and oilseed rape female parents in each ridge, and releasing the chrysomyia megacephala to carrying out pollination. According to the method, the chrysomyia megacephala is subjected to low-temperature domestication, the cold resistance and low-temperature activity of the chrysomyia megacephala are improved, the chrysomyia megacephala is released into the greenhouse, and therefore, a brand-new mode for improving the early spring pollination efficiency of insects is provided for agricultural production.

Description

technical field [0001] The invention relates to the technical field of domestication and application of pollinating insects, in particular to a method for low-temperature domestication of insects for pollination of early spring crops. Background technique [0002] Pollination is the weakest link in the production of many crops, and increasing pollination can increase crop yields more effectively than conventional agricultural inputs. A large number of crops depend on insects for pollination, and insect pollination can increase the yield of different crops by 18%-71%. Global declines in the number and species richness of wild bees and reduced populations of farmed bees have increased crop dependence on other pollinating insects. [0003] Diptera insects are the largest group of flower visitors except the Hymenoptera bees. Research on the activity of dipteran insects has shown that their foraging behavior is better suited to fluctuating planting environments than bees. Adve...

AI Technical Summary

Problems solved by technology

[0006] 1. Most of the pollinating insects in traditional artificial breeding are bees, and the technology of bee breeding is difficult, and it is difficult to popularize it to small growers;

[0007] 2. Bee breeding needs to go to different places to visit flowers with the seasons, and the entire beehive needs to be moved during transportation, which consumes labor and costs;

[0008] 3. Bees pollinating insects have poor stress resistance and are susceptible to pathogen infection and pesticide poisoning, resulting in population shrinkage;

[0009] 4. Bees need to survive the winter in winter, and bee colonies need to rejuvenate in early spring. If the bee colonies are directly used for pollination in greenhouses or greenhouses, a large number of bees will die;

[0010] 5. In greenhouses and greenhouses, a large number of bees will die due to hitting the net, and there is also a risk of stinging people;

[0011] 6. Bees do not leave the hive under continuous rainy or low temperature conditions, resulting in insufficient pollination of crops;

[0013] 8. Although Chrysocephalus chinensis has low breeding cost and simple technology, it can also visit flowers in bad weather, but the temperature limits its flower visiting vigor and pollination efficiency
