What are CRYPTOLAEMUS MONTROUZIERI adults?
CRYPTOLAEMUS MONTROUZIERI is an Australian ladybird that can be used for the biological control of various mealybug species. They can be released in the greenhouse year-round and in the garden during summer. This product contains the adult ladybirds. These beetles are black, have an orange head and are 3-4 mm big. The adult predatory beetles mostly walk through the crop. They rarely fly, only shortly after having been introduced.
How do CRYPTOLAEMUS MONTROUZIERI adults work?
The beetles feed on all stages of mealybug. In addition, the female beetles lay their eggs in the woolly egg masses of the mealybugs. The young larvae that emerge from these eggs will in turn feed on the mealybugs. The beetles lay less eggs if the mealybug species do not produce an egg mass. After a mealybug has been fed on, a white, empty shell remains on the plant. CRYPTOLAEMUS MONTROUZIERI adults are most effective in mealybug hot spots.
How to combine CRYPTOLAEMUS MONTROUZIERI adults
For as fast result, you can also release CRYPTOLAEMUS MONTROUZIERI larvae. These larvae are voracious and will consume numerous mealybugs during their development. The larvae are perfect for removing mealybug hot spots. To target the more dispersed mealybugs, we recommend to combine them with parasitoids, such as LEPTOMASTIX DACTYLOPII and LEPTOMASTIDEA ABNORMIS against citrus mealybug or CRYPTANUSIA AUREISCUTELLUM and ANAGYRUS FUSCIVENTRIS against long-tailed mealybug.
