Solutions for a better world
The Chinese mantis (tenodera sinensis) is a beneficial insect with a fascinating appearance and behaviour. Originally from Asia, this species was imported to the United States in 1896 and can now be found throughout the United States and in southern Quebec. The Chinese mantis is the largest mantis species in North America.
This predator feeds on several types of insects, such as crickets, grasshoppers, caterpillars, butterflies and moths, plant bugs, flies and more. First-stage nymphs mainly eat small flies and other small insects (aphids, leafhoppers, etc.). During its development, the Chinese mantis will attack larger prey. Basically, anything it can catch and devour!
Chinese mantises are shipped in egg pods, a sort of rigid foam cocoon that contains nearly 100 eggs. The baby mantises will emerge 15-60 days later, at room temperature.
The young mantises will reach maturity at the end of summer and will reproduce from August to late September. Females will lay one or more egg pods, with the baby mantises spending the winter in this form. The adults will die at the end of the summer.

On the 150 species of trichogramma, 20 of them are used in biological control.
