The parasitic wasp Aphidius colemani is a polyphagous parasitoid which belongs to the family Braconidae, attacking over 40 species of aphid. The wasp is native to North America and common in North Africa, Middle East, India and Mediterranean region.
Aphidius colemani controls chiefly the green peach aphid, Myzus persicae, the tobacco aphid, Myzus nicotianae and the cotton aphid, Aphis gossypii.
Aphidius colemani is efficient in all crops where the target aphids are present as pests, including: sweet pepper, tomato, cucumber, ornamentals, herbs, and field crops such as maize and cotton.
The adults are small slender wasps with black, brown and yellow coloration with brown legs and long antennae. Aphidius colemani’s size depends on the size of the parasitized aphid, but is usually about 2 mm long.
Aphidius colemani’s activity is optimal between temperatures of 20-30°C. Below 15°C, the adult is inactive. An adult female parasitoid may perform several hundred oviposition attempts during its lifespan, out of which up to 200 eggs will develop successfully to adulthood.
BioAphidius – The Product
- BioAphidius takes the form of mummies containing the parasitoid’s pupa. Thus the product reaches its destination everywhere in the world when it is “fresh”, with negligible mortality in shipping and with enhanced performance.
- The commercial package contains 100, 200 or 500 mummified aphids mixed in fine sawdust. At least 50% of the emerging adults are females.
- BioAphidius is utilized both indoors and outdoors.
- BioAphidius is compatible with selective conventional chemicals (according to the list of pesticides provided by BioBee).
- Adult wasps will emerge from the mummies within 1-5 days (depending upon ambient temperatures). Immediately upon emergence, the wasps will mate and then begin searching for a host suitable for parasitization.
- BioAphidius is shipped in temperature controlled Styrofoam boxes which must be kept intact until reaching the end-user.
- BioAphidius should be hanged on the plant as close as possible to aphids‘ hotspot (if detected).
Do not sprinkle the mummies actively from the container.
- If ants are present at the aphid hotspots, they must be destroyed. Ants encourage honeydew secretion by the aphids, transfer them from one place to another and protect them by actively interfering with the parasitoid.
- Keep the product at room temperature (not refrigerated!) until emergence has started (appearance of a few parasitic wasps). Avoid direct exposure of the product to sunlight!
- Two-three weeks following BioAphidius release (depending upon temperature, low temperatures could extend time to several weeks), mummified aphids can be clearly detected. The subsequent established generations of the parasitoid will effectively control the aphids in the longer run.
- BioAphidius Introduction rate should be determined according to the nature of the crop and according to the rate of aphid infestation.
All products are tested to meet specification requirements before leaving the factory.
BioBee is not responsible for the outcome of implementation in the field, as it has no control over the method of application, local conditions, treatment/storage of product not according to instructions, etc.
