• Insect control by insect growth regulators broadcast by volatilization
  申请人：Wellmark International

  Insect control through the use of an insect growth regulators is achieved by volatilization of the active compound from a point source in a spatial region such as a room, to diffuse through the air in the region toward objects in the region such as a carpet or a piece of furniture. The ability of the insect growth regulator to retain its activity when applied in this manner, even after periods of time in excess of one month following volatilization, is surprising in view of pre-existing methods of application that involved application of the insect growth regulator directly to the surface or object of interest in liquid form.

  使用昆虫生长调节剂控制昆虫是通过活性化合物从空间区域（如房间）的点源挥发，通过区域内的空气扩散到区域内的物体（如地毯或家具）来实现的。昆虫生长调节剂以这种方式施用时，甚至在挥发后超过一个月的时间内仍能保持其活性，这在以前的施用方法中是令人吃惊的，因为以前的施用方法是将昆虫生长调节剂以液态形式直接施用到有关表面或物体上。
• Method for preventing pests from entering a building structure

  Disclosed is a method for preventing pests from gaining entrance to a building structure. The method incorporates use of an article comprising a length of fibrous fabric and a plurality of adhesive strips. The fabric is designed for adhesive attachment to a building structure adjacent points of entry and the adhesive strips are designed for adhesively attaching the fabric in snug adjacency to the outfitted building structure. The fabric is impregnated with at least one pesticide composition and has outwardly extending fibers for entangling the legs of pests attempting to gain entrance to the building structure by maneuvering across the fabric to points of entry. These outwardly extending fibers thus directly deposit pesticide composition on the pests for preventing them from gaining entrance to the building structure. Importantly, the fabric is brilliantly colored or has highly light reflective coloration for attracting the pests to the pesticide-impregnated fabric for contact treatment.

  本发明公开了一种防止害虫进入建筑结构的方法。该方法包括使用一种物品，该物品由一段纤维织物和多个胶条组成。纤维织物用于粘附到邻近入口点的建筑结构上，而粘胶条用于将纤维织物粘附到紧贴的建筑结构上。织物至少浸渍了一种杀虫剂成分，并具有向外延伸的纤维，用于缠住试图穿过织物进入建筑结构的害虫的腿，使其到达进入点。因此，这些向外延伸的纤维可直接将杀虫剂成分涂抹在害虫身上，防止它们进入建筑结构。重要的是，这种织物颜色鲜艳或具有高度反光性，可将害虫吸引到浸过杀虫剂的织物上进行接触处理。
• Juvenile Hormone Analogs for Control of Leafhopper and Treehopper Pests

  The present invention pertains to compounds and methods for controlling treehopper and leafhopper pests, such as the glassy-winged sharpshooter (GWSS), while conserving their parasites (such as parasitoid wasps). In one embodiment, the compound is a juvenile hormone analog such as methoprene, kinoprene, and hydropene. The invention also concerns pesticidal compositions comprising the compounds of the invention and a pesticidally acceptable carrier. The invention further concerns methods for controlling pests, such as GWSS, while conserving their parasites, by applying a compound or composition of the invention to the pest or pest-inhabited locus.
