Effective against citrus mealybug
What does LEPTOMASTIX DACTYLOPII look like?
The adult parasitoids are about 3 mm in size, yellow-brown coloured and have slim dark antennae. Females have bended antennae, while males do not. Males have less hairy antennae than females. Males are in general slightly smaller and darker. LEPTOMASTIX DACTYLOPII mostly parasitizes large citrus mealybugs instars. Parasitized mealybugs will bulge into yellow, hard mummies. After a while, young adult parasitoids emerge through a hole on the top-end of the mummy.
How does LEPTOMASTIX DACTYLOPII work?
Female parasitoids lay eggs in third instar and young adult mealybugs. A single parasitoid emerges from one mealybug. The parasitoid larvae eat the mealybug from the inside out. After a while, a young adult parasitoid emerges through a hole on the top-end of the mummy. The size of the mealybugs determines the parasitoid sex; a small mealybug produces usually a male, while a big mealybug leads to a female. A female parasitoid lays 300-400 eggs during her life. These develop into adult parasitoids in 20-40 days. Adult parasitoids have a lifespan of 2-3 weeks.
When can LEPTOMASTIX DACTYLOPII be applied?
LEPTOMASTIX DACTYLOPII can be applied in different situations: ornamentals, horticulture, indoor- or botanical gardens. The parasitoid prefers higher temperatures. Its efficacy is optimal in summer, but it is also very active and effective in spring and early fall. This species is not heavily affected by daylength and humidity. LEPTOMASTIX DACTYLOPII is sensitive to (side)effects of pesticides, especially when parasitoids populations are establishing.
For heavy mealybug infestations a combination with the predatory beetle CRYPTOLAEMUS MONTROUZIERI is advised. LEPTOMASTIX DACTYLOPII can also be used in combination with the parasitoid LEPTOMASTIDEA ABNORMIS, which controls the smallest mealybug stages.
