Extended data:
1, lifestyle
Mantis has the habit of killing each other in nymph stage, but the self-mutilation rate is different because of the different environment of different species. Generally, the amount of cannibalism is 10% ~ 30%, and it can reach 90% when it is high, which is also a difficult problem that puzzles the large-scale artificial reproduction of mantis. In nature, cannibalism may be the mechanism of mantis population control in a certain number, which also successfully affects niche differentiation.
2. Feeding methods
(1) oocysts preservation: According to indoor and outdoor observation, locust oocysts generally start to hatch when the temperature is stable at 20℃. Therefore, oocysts collected from June 1 1 to February 12 can be stored at normal temperature until April, but they should be kept dry, moisture-proof and rat-proof. After May, it will be stored in the refrigerator according to the needs of temperature and utilization.
(2) Outdoor large-scale enclosure culture: In late May, mantis eggs to be hatched are moved into the enclosure, and 50 mantis eggs are released per square meter after hatching. Plant all kinds of barriers such as dwarf trees and cotton in the mulch, establish a natural environment, reduce slaughter, cover reed mats in sunny and rainy days, apply paste feed on the branches and leaves of the barriers, and put cakes in small rubber plugs. Remove moldy residues in time to keep the feed fresh.
