Aphelinus abdominalis - Description

While Aphelinus abdominalis targets a variety of aphid pests, they are particularly effective against foxglove and potato aphids. It may be used at higher rates in conjunction with other beneficial insects, such as Aphidius colemani and Aphidius ervi, to bring moderate infestations under control. These parasitoids are known to live longer and lay eggs over a longer period than other parasitoids. They also eat aphids rather than just parasitizing them, making them a valuable addition to any pest management program. Females have a black thorax and yellow abdomen and can measure up to 3mm in length. Males are smaller and darker in color. A female can lay up to 250 eggs in a 3-week cycle. After 3-5 days the eggs hatch into larvae that will feed on the internal contents of the aphid for about 5-10 days. After completing development, the larvae pupate, and a new generation of adults emerge from the aphid mummies continuing the reproductive cycle for sustainable aphid management. The first mummies should be seen in your crops in a minimum of 14 days after  the first release.
