ABOUT APHIDIUS ERVI:
Aphidius ervi are around 4-5mm long and have a black body with translucent wings. They are often mistaken for small flies due to their size and delicate appearance. Aphidius ervi is widely distributed and commonly used in biological pest control programs.
Sex ratio is 60-70% female. Each female can lay more than 300 eggs. The female adult will lay an egg directly into the aphid body where it hatches and the larvae will consume the aphid’s body from within. When A. ervi larvae mature, the host aphid transforms into a black mummy over 7 days. Subsequently, it takes another 14 days for the mummy to mature into an adult, which emerges through a hole at the mummy's rear. Expect to observe the first mummies in your crops at least 14 days after the initial release.
Indoors and outdoors on a wide range of plants in greenhouses, vegetable crops, soft fruits, tree nurseries, and various other types of crops.

Its important to note that these introduction rates serve as a general guideline and may vary depending on the specific pest, plant type, and level of infestation.
