Aphidius Species Aphid Parasitic Mini-Wasps

These 2-3 mm. mini-wasps are best used for preventing the establishment of more than 40 species of aphids. They can also tackle light to medium infestations. And, if established, they can adequately protect a crop throughout the season, with some possible exceptions in late summer.

Aphidius Species Aphid Parasitic Mini-Wasps are best in the prevention of small infestations of Aphids. There are different species of the mini-wasps that will feed on the different varieties of Aphids. So depending on the plant that you have Aphids on, you will want to match up the correct mini-wasps. The mini-wasps are effective because they lay eggs inside the Aphids, then the larvae will hatch inside the Aphid and will slowly weaken the Aphid and kill it. A. matricariae, which are normally shipped as pre-emerged, pre-fed adults.

The Aphidius spp., as parasitoids, work by laying eggs in aphids. And they can lay 200-300 eggs! The wasps’ larvae which hatch from the eggs, slowly weaken and kill the aphids from within (endoparasitism). The aphids then turn into “mummies” as the wasps pupate. The life-span of these parasitoids is roughly 2 weeks in their immature stages, then 2 weeks as adults. The conditions for optimum performance will be between 64-75°F with a relative humidity of around 80%. But these are optimum conditions and not necessarily a prerequisite of successful implementation. Please note, however, significantly cooler or warmer temperatures and humidity fluctuations may hamper reproduction and development a certain degree.

A. matricariae, because they are shipped as pre-mated adults, offer the benefits of a high female sex ratio of 95:1, fast oviposition and freedom from hyperparasites.
