Effective against citrus mealybug
What does LEPTOMASTIDEA ABNORMIS look like?
LEPTOMASTIDEA ABNORMIS is a small parasitoid, which is 0.75-1.5 mm in size. Both males and females have yellow, brown or gray body colours. Females often have a light band across the abdomen. The wings have three black bands and have a striking perpendicular position. Males are in general smaller than females and have hairy antennae. Mealybugs parasitized by LEPTOMASTIDEA ABNORMIS will bulge into orange-yellow colored pupae, that are often difficult to find due to their small size. The pupae have a small exit hole at the end after the new adult wasps have emerged.
How does LEPTOMASTIDEA ABNORMIS work?
Female LEPTOMASTIDEA ABNORMIS deposit their eggs mainly in second instar citrus mealybug, but also in first and third instar citrus mealybugs. One egg per mealybug is laid. The parasitoid larvae will feed on the mealybug from the inside. Only a dark, orange cocoon remains of the mealybugs, which are difficult to find in the crop. The cocoon will drop from the plant after a while. A female lays 200-300 eggs during her live (30 days at 22°C). These eggs will develop into adults in three weeks.
When can LEPTOMASTIDEA ABNORMIS be applied?
LEPTOMASTIDEA ABNORMIS is applied indoors and in greenhouses to control citrus mealybugs (Planococcus citri). Consider repeated introductions. LEPTOMASTIDEA ABNORMIS has relatively few requirements towards temperature, humidity and daylength and can be used very well in spring. Experience learns that is takes a longer period before effects of the product are visible. LEPTOMASTIDEA ABNORMIS settles relatively easy in the crop. The product is sensitive to chemical pesticides. Ask advice for deployment strategies.
For heavy mealybugs infestations a combination with the predatory beetle CRYPTOLAEMUS MONTROUZIERI is advised.
