Under laboratory conditions, the effects of thiamethoxam were investigated in larvae, pupae and emerging honey bees after exposure at larval stages with different concentrations in the food (0.00001 ng/μL, 0.001 ng/μL and 1.44 ng/μL).... more
Africanized honey bees (Apis mellifera, Hymenoptera: Apidae) in Brazil are tolerant of infestations with the exotic ectoparasitic mite, Varroa destructor (Mesostigmata: Varroidae), while the European honey bees used in apiculture... more
Using historic data sets, we quantified the degree to which global change over 120 years disrupted plant-pollinator interactions in a temperate forest understory community in Illinois, USA. We found degradation of interaction network... more
Insects are everywhere and in great numbers. Their impact on us is unquestionable, but a number of scientists are expanding what we can learn from these creatures – whether for environmental reasons or to help humans to live longer. One... more
Interactions between pesticides and parasites are believed to be responsible for increased mortality of honey bee (Apis mellifera) colonies in the northern hemisphere. Previous efforts have employed experimental approaches using small... more
Creamed honey is a non-liquid form of honey. This type of honey is produced mainly by adding nuclei (i.e. previous creamed honey) to liquid honey. In this research, chemical characteristics of creamed honey produced using two nuclei... more
Trophallaxis among adult worker honeybees is the transfer of liquid food by mouth from one individual to another. Within the colony, nectar foragers perform offering contacts (as food-donors) to transfer the contents of their crops to... more
Network analyses of plant-animal interactions hold valuable biological information. They are often used to quantify the degree of specialization between partners, but usually based on qualitative indices such as 'connectance' or... more
Thin-layer chromatography of ethanolic extract of propolis (EEP) from the continental and Adriatic regions of Croatia showed that 72.2% of propolis samples contain galangin, 88.8% of samples contain kaempferol, naringenin and apigenin and... more
Michigan’s current level of food production and its agricultural economy are in jeopardy due to drastic honey bee population declines across the state over the past seven years. This problem should be a priority for policy makers; honey... more
The mode of action of honey bee pollen (HBP) was investigated in Nile tilapia (Oreochromis niloticus) challenged with Aeromonas hydrophila. Thus, fish with an average weight of 29 ± 3 g were divided into four groups, and fed with HBP-free... more
Honey bees undergo a physiological transition from nursing to foraging approximately 21 days after adult emergence. This transition is delayed by ethyl oleate (EO), a primer pheromone produced by foragers when exposed to ethanol from... more
Queenless workers of the Cape honeybee (Apis mellifera capensis) can develop into reproductives termed pseudoqueens. Although they morphologically remain workers they become physiologically queenlike, produce offspring, and secrete... more
Histone post-translational modifications (PTMs) play a key role in regulating a variety of cellular processes including the establishment, maintenance and reversal of transcriptional programmes in eukaryotes. However, little is known... more
The in vitro rearing of honey bee larvae becomes an important tool for modern studies. Honey bee larvae are very fast in their growth. Thus, it is not easy to control the larvae within the beehives. Therefore, the need for rearing the... more
