What does CRYPTOLAEMUS MONTROUZIERI look like?

CRYPTOLAEMUS MONTROUZIERI beetles are black with an orange head. They are 3-4 mm big. The yellow eggs are oval-shaped and are deposited in the mealybug’s egg masses, which make them difficult to find. CRYPTOLAEMUS MONTROUZIERI larvae are covered in waxy filaments, which makes them resemble mealybugs. They can be distinguished from mealybugs by their behaviour: beetle larvae walk faster. They are also slightly fluffier. The beetle pupae look very much like the larvae. They are slightly bigger, fluffier and do not move. The pupae are usually located in sheltered places. Both the adult beetles and the larvae feed on mealybugs. After feeding, a white, empty structure remains on the plant.

How does CRYPTOLAEMUS MONTROUZIERI work?

CRYPTOLAEMUS MONTROUZIERI larvae can consume up to 30 mealybugs a day, which makes them very efficient removers of mealybug hotspots. They eat all stages of several mealybug species, such as citrus mealybug and long-tailed mealybug. After feeding, remnants of the mealybug remain on the plant. The adult beetles need the mealybug’s egg masses to lay eggs in. Therefore, CRYPTOLAEMUS MONTROUZIERI beetles are best to use against citrus mealybug.

When to use CRYPTOLAEMUS MONTROUZIERI

CRYPTOLAEMUS MONTROUZIERI is applied in greenhouses and other indoor environments to combat several mealybug species. They are most effective when the temperature exceeds 20°C and the relative humidity is at least 40%. Take into account that several introductions are necessary.
