Aphelinus abdominalis - Aphid Control




Over 200 species of aphids. Targets larger-bodied aphid species such as the Potato aphid, Foxglove/Glasshouse aphid, and the Green Peach aphid.


Aphelinus abdominalis, a natural predator of aphids, is an effective solution for controlling aphid infestations. This small insect measures approximately 3mm in length and features short legs, short antennae, and a yellow abdomen. It is particularly well-suited for preventing aphid infestations during the early risk period. To address moderate infestations, it can be used alongside other beneficial insects at higher rates.
The reproductive cycle of Aphelinus abdominalis is notable, with a female capable of laying up to 250 eggs in a three-week period. These eggs are deposited directly into the bodies of aphids. Once hatched, the larvae feed on the aphid from within, eventually leading to the formation of a black, leathery mummy after approximately seven days. Within this mummy, the parasite larva fully develops over the course of 14 days, ultimately emerging as an adult wasp. The appearance of the first mummies in your crops can be expected at least 14 days after the initial release of Aphelinus abdominalis.


To support the well-being of emerged adults, a reliable food source is provided. Aphelinus individuals have a tendency to move around crops by walking rather than flying, which means they tend to stay on the crop and are less likely to leave the greenhouse environment.



Indoors and outdoors on a wide range of plants in greenhouses, vegetable crops, ornamental crops, soft fruits, tree nurseries, horticulture landscapes, and various other types of crops.



Release parasitic wasps onto infested plants by opening the bottle and placing it at the base of the affected plant. Best results are obtained by making low rate preventative releases when there is a risk of aphids invading the crop. If larger outbreaks of aphids are found, larger release rates should be made immediately.

LIGHT INFESTATION: 80 insects per 40 sq. ft. of canopy with two weekly introductions into infested areas.

HEAVY INFESTATION: 160 insects per 40 sq. ft. of canopy with two weekly introductions into infested areas.

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.



Make use of Gardening Zone's Hanging Release Boxes for a clean and efficient method of deploying your predators. Our release boxes are designed to concentrate your predators on infested areas, allowing for targeted pest control without any mess, and also help to keep your product dry.


It's crucial to correctly identify the specific aphid species at hand. Keeping a close eye on your crop and releasing Aphelinus abdominalis in a timely manner can greatly help in managing the pest problem. It's important to be aware that the survival of A. abdominalis may be adversely affected by the use of pesticides, wetting agents, and spreader-stickers.

Remove yellow sticky cards for the first few days after release.
