Abstract: A tray for positioning in an exit path of a bee hive comprises a base, a bee entrance end, and a bee exit end. Spaced apart side walls extend upwardly from the base. The sidewalls extend generally lengthwise between the bee entrance end and bee exit end. A plurality of posts extend upwardly from the base and are positioned between the bee entrance end and the bee exit end. The posts are generally circular in cross-section. The posts act as obstacles around which the bees must walk to reach the bee exit end from the bee entrance end.

Abstract: A bee vectoring apparatus includes a tray for positioning in the exit path of a beehive. The tray includes a bottom, a bee entrance end, and a bee exit end. The apparatus includes a tray lid positioned above the bottom, with first and second barrier walls extruding downwardly from the lid. A ceiling extends between bottom ends of the first and second barrier walls.

Abstract: The electronic field guide of the invention presents multiple data items to an end user, via the display of a stationary computer, and allows the user to select particular ones of the multiple data items that are available. Multimedia data files corresponding to the selected items are then downloaded onto a portable computing device such as a personal digital assistant (PDA). Thus, the user will have access to a subset of the overall data on his portable PDA. This invention may be used, for example, to provide electronic field guides in such applications as bird watching, where the multimedia data files contain the images of birds, audio files containing their songs, and text data. The main data may be stored on a CDrom, be made available over the Internet, or be provided in some other manner.

Abstract: A method for provisioning electronic field guides comprising the steps of: presenting multiple data items to an end user, via the display of a stationary computer; and responding to the selection of particular ones of said multiple data items by said user, by: downloading multimedia data files corresponding to said particular ones of said multiple data items, to a portable computing device; whereby said portable computing device may present the multimedia content to the end user in the field.

Abstract: There are disclosed therapeutic microcapsules for beneficial insects having a non-toxic matrix with a medicament for treating a beneficial insect disorder substantially uniformly distributed therethrough and therapeutic compositions in which the microcapsules are in a carrier. Also disclosed is the method of treating beneficial insect disorders with such microcapsules and compositions.
