What does ACEROPHAGUS MACULIPENNIS look like? 

Adult parasitoids are approximately 1.5-2 mm in size and greywith short antennae that have a striking white tip. ACEROPHAGUS MACULIPENNIS are predominately female. The parasitoids are very active and make quick, abrupt movements. Parasitized mealybugs can be recognized as yellow-orange, irregularly shaped cocoons with several dark spots. One empty pupa has multiple exit holes from which new adult wasps emerged.

How does ACEROPHAGUS MACULIPENNIS work? 

This parasitoid builds up big populations very quickly and can sustain itself for a long time at low mealybug levels. ACEROPHAGUS MACULIPENNIS parasitizes mainly older mealybugs stages. Per mealybug 3-7 eggs are deposited, depending on the size of the mealybug. All eggs can develop into new parasitoids. The development time from egg to adult is shorter than for most other parasitoid species that control mealybugs. It takes 14-18 days to develop from egg to adult. A female’s life span is 2-3 weeks and during that time she can deposit about 200 eggs. 

When can ACEROPHAGUS MACULIPENNIS be applied? 

ACEROPHAGUS MACULIPENNIS is used in greenhouses and indoor plantings to control obscure mealybug (Pseudococcus viburni) (old name: P. affinis). ACEROPHAGUS MACULIPENNIS also parasitizes other mealybug species. After parasitization, mealybugs remain alive for a few days after which they hide and turn into a pupaThe pupa will remain on the plant and will drop from the plant after emergence of the parasitoid. Consider multiple introductions. The product is sensitive to several chemical pesticides. Ask advice for deployment strategies.
