Concern about adverse effects of pesticides on the
environment and of residues in food products has
increased the need for improved delivery systems to
reduce the quantities of pesticides used and to target
their application more effectively

Adhesive Powders. Two adhesive powders were investigated:
an electrostatic wax powder, Entostat, which
is refined carnauba wax produced by the fronds of the
Brazilian wax palm, Copernica cerifera Martius (Palmae);
and a proprietary metallic powder, Entomag.

Further work is planned to
examine the effect of these adhesive powders on the
behavior of other important insect pests, such as cockroaches
and stored-product moths.

Integrated pest management firm Exosect Technology - on the back of five years of research - has developed Exomite Pro Entostat to act as a delivery system for a wide range of pest control solutions including Thymol, which is effective in controlling the Varroa mite. The Entostat powder is made out of a palm tree wax and has electrostatic properties that develop an electrostatic charge, even through very slight movement. It sticks to bees when they come into contact with the powder which can be passed from one bee to another. The technology also means that only minute quantities of Thymol are needed, reducing the potential for Thymol residues in honey crops.

Exosect managing director Martin Brown said: "Entostat powder is impregnated with small quantities of Thymol and sprinkled on top of the brood frames. Some drops down through the frames on to the bees and the remaining powder is removed by the colony. The powder is taken up by the bees in this process. "The presence of the powder on the bee increases grooming activity, which combines with the Thymol to cause the Varroa mites to drop off the bees and die. Exomite Pro has proven to provide the fastest knockdown for Varroa when compared to other Thymol-based products."

He added: "This solution is the result of investment by individuals and organisations with a vision of green technology and a desire to make a positive environmental and ecological difference. However, as a small company we are not currently in a position to make this particular product readily accessible. We are actively seeking ways in which this might be resolved and the product made available on a worldwide basis."
