The comparative analysis of biology and concerned morphology of the main groups of solitary and primitively social bees species was carried out. The main prerequisites for the origin of eusociality were determined. The method of industrial artifical breeding of bumblebees was elaborated. Some physiological mechanisms of caste determination in bumblebees were shown. The mathematical model for alfalfa pollination process control was created. The functional morphology and biomechanics of the pretarsus in Hymenoptera were investigated. The three-dimentional graphic model was created and the mechanical model was built for demonstration of the interaction of the pretarsus sclerites in the closed and opened state of the arolium.The ultrastructural investigations of the inner architecture and external microsculpture of the insect euplantulae had shown, that adhesive properties of the pulvillae material are adopted to the mass of the body and square ofthe pulvillae in such a way, that lateral adhesion is not changed during onthogenesis .The neurones, which are maximally sensitive to the approach from short distance, were first registed in the abdominal chain of Hymenoptera. These neurones can take part in the premotor commands transmission in the reactions of nest search and can launch the landing reaction or defence reflex.The building behaviour of the honey bees Apis mellifera L. was investigated under intact and experimental conditions. The specific composition of some insect groups of the fauna of Ukraine was investigated Product Description popup.authors popup.nrat_date 2020-04-02 Close
