The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent. In the current study, temperature-dependent development of the two-spotted ladybeetle A. bipunctata L. (Coleoptera: Coccinellidae) was evaluated on Myzus persicae (Sulzer) (Hemiptera: Aphididae) and a factitious food consisting of moist bee...

Structuring the information and knowledge needed to implement a factory, as well as doing its control and management by computer systems, is the purpose of the meta-model and solutions here presented. This meta-model includes: an object-oriented model to structure the needed information and knowledge; a model for manufacturing systems; a prototype that integrates the two previously referred mod...

Spindles from the gonads of five insect species were examined after conventional preparation for electron microscopy. The aim of the study was to determine (1) the range of variation of the spindle membranes between mitotic and meiotic cells and (2) the correlation of possible differences with the microtubule content of the spindles. The study involved four moth species, Ephestia kuehniella, Ph...
