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.

 

ABOUT APHIDIUS COLEMANI:
Adult parasitic wasps are black 2-3mm long with long antennae and narrow abdomens. Adult females lay eggs from their abdomen by quickly curling their abdomen and puncturing an aphid simultaneously with their ovipositor. The egg, once inside the aphid, will hatch into a larva and consume the aphid. The larvae then pupates (spins a cocoon) inside the dead aphid. The mummified aphid swells into a characteristic round, golden brown mummy. The emerging adult will cut a symmetrical hole at the bottom end to escape from the mummified aphid. After injecting the aphid with an egg, it takes about a week for the mummy to form and then another week for the adult to appear. Each female can lay up to 300 eggs.

 

ABOUT APHELINUS ABDOMINALIS:

Aphelinus abdominalis is about 3mm long with short legs, short antennae, and a yellow abdomen. A. abdominalis is not a strong flyer, so should be placed near aphid infestations. This beneficial insect is best suited for preventing outbreaks of aphids during the early risk period.

A female can lay up to 250 eggs in a 3 week cycle. 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. abdominalis 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.
