Juvenile hormone (JH) regulates developmental and physiological processes in insects. In bumble bees, the hormone acts as a gonadotropin that mediates ovary development, but the exact physiological pathways involved in ovary activation and subsequent egg laying are poorly understood. In this study, we examine how queen hibernation state, caste, and...
Gestalt psychologists posited that we always organize our visual input in the best way possible under the given conditions. Both weakening or removing unnecessary details (i.e., leveling) and exaggerating distinctive features (i.e., sharpening) can contribute to achieving a better organization. When is a feature leveled or sharpened, however? We in...
Varroa destructor mites and the viruses it vectors are two major factors leading to high losses of honey bees (Apis mellifera) colonies worldwide. However, honey bees in some African countries show resilience to varroa infestation and/or virus infections, although little is known about the mechanisms underlying this resilience. In this study, we in...
The influence of biological preparations on the degree of rooting of different types of junipers is considered. The treatment options with Azolene, Mizorin and Flavobacterin were more effective for all the observed objects of the study. / Рассмотрено влияние биологических препаратов на степень укоренения разных видов можжевельников. Наиболее эффект...

In recent years, Liorhyssus hyalinus (Fabricius) (Hemiptera: Rhopalidae) and Nysius simulans Stål (Hemiptera: Lygaeidae) have emerged as important pests of quinoa in Peru, when the crop started to be cultivated at relatively low elevations. The potential of the native lacewing Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) was evaluated as a...

По изученным материалам хвойных лесов, пораженных сибирским шелкопрядом, расположенным в Енисейском районе Красноярского края, проанализирована возможность проведения химической переработки фаутной древесины с целью получения технической целлюлозы. Технический этап заключался в определении процентного соотношения здоровой части древесины к поврежде...
The stimulation of biological processes by sublethal doses of insecticides or other stressors is known as hormesis. Here, we have evaluated whether exposure to field-relevant or low concentrations of neonicotinoids induce changes in the reproductive capacity of the bulb mite Rhizoglyphus robini (Acari: Acaridae). Among the tested neonicotinoids imi...
This paper provides a fresh look at the specificity of French ART rules. Re-exploring the genesis of sperm banks and the emergence of ART regulation in the 1970s and 80s involves considering a sequence during which several options were competing and no “national path” was defined. Sperm banking constituted the locus of tensions concerning the socia...
