DESCRIPTION
Scientific Name: Aphidius ervi
ERVI are generalist parasitoids, a little larger than A. colemani. They specifically target larger aphid species. Adults are approximately 3-4mm in length with a slender, translucent, black to dark brown body, relatively long antennae, and transparent wings with characteristic veins. Given its small size, ERVI may require magnification to be visible, but these tiny parasitoids are a formidable predator against a wide variety of aphid species. Adult parasitoids are extremely nimble, actively searching for aphid colonies where females will inject eggs into hosts. After 3-5 days the eggs hatch into larvae that develop while feeding on the aphid for the next 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. Females can lay more than 100 eggs during their 2-week lifespan.
TEMPERATURE
50-86°F
INTRODUCTION RATES
1-5 insects per 10 sq. ft., weekly, 2-3 times.
It's important to note that these release rates serve as general guidelines and may vary based on the specific pest species, the crop or plant being treated, and level of infestation. Proper monitoring of the infestation and the subsequent effectiveness of the released beneficial insect population is crucial for determining the success of the biological control strategy.
STORAGE
Do not store adults. Store pupae at 39-46°F for no longer than 48 hours.
PRO TIPS:
Proper identification of the aphid species is important. Monitoring the crop closely and introducing beneficial insects early will help in control pest populations.
Pesticides, even wetting agents, and spreader-stickers may adversely affect beneficial insects' survival. Broad spectrum and systemic insecticides are toxic.
