There are disclosed novel formulations of avermectin compounds and a substrate which demonstrate markedly enhanced insecticidal activity over that which would be observed with other formulations. Avermectin natural product compounds and certain semisynthetic derivatives thereof are compounds known to be highly effective broad-spectrum antiparasitic and pesticidal agents. However, when such compounds are formulated into the instant composition, the activity observed is increased to at least 10-times that which would be expected. The instant substrate is preferably a highly dispersed, amorphous form of hydrophyllic silicon dioxide.

Novel synergistic compositions

Insect lure

In an insect lure for attracting and killing insects, particularly the housefly, a tubular formed base member incorporates a pair of end caps, at each end of the tube, with the tubular member being formed of a kraft base paper, wrapped with an outer layer of white paper, then being covered with a fluorescent paper that provides a superficial luminescent surface of attraction to such insects, said luminescent material is overprinted with silhouettes of insects, such as the housefly, usually in a clustered arrangement, and may have a poison located at the focal point of such cluster for enhancing the kill of any attracted insect, and, finally, a coating of a lacquer is applied over the fluorescent attractant, including any silhouettes imprinted thereon, and a highly viscous tackifier material is applied upon the lacquer barrier for enhancing insect adherence thereto. The process of attracting such insects, particularly the housefly, is encompassed in this invention and which comprises the formation of the previously identified type tubular base member, having its ends capped, and positioning such graphic silhouettes of flies upon a luminescent background coating with the then application of a lacquer, and then applying the highly viscous tackifier material to its surface.
