Seasonal screening of pesticide residues in beehive products collected from different districts in Egypt.

Pesticides are of immense importance in agriculture, but they might contaminate bees' products. In this study, samples of honey, pollen, and beeswax were collected, seasonally, from apiaries in Toshka (Aswan), El-Noubariya (El-Beheira), and Ismailia (Ismailia) cities in Egypt. The pesticide residues were analyzed using the GC-MS after being extracted and cleaned using the QuEChERS method.

The response of heat shock proteins in honey bees to abiotic and biotic stressors.

Honey bees, Apis mellifera, are the most important managed pollinators worldwide. They are highly impacted by various abiotic and biotic stressors, especially temperature extremes, which can lead to cellular damage and death. The induction of heat shock proteins (HSPs) has been recorded in honey bees as a response to various types of stressors.

Oxalic acid application method and treatment intervals for reduction of Varroa destructor (Mesostigmata: Varroidae) populations in Apis mellifera (Hymenoptera: Apidae) colonies.

Oxalic acid (OA) is a popular miticide used to control Varroa destructor (Mesostigmata: Varroidae) in western honey bee (Apis mellifera L.) (Hymenoptera: Apidae) colonies. Our aim was to investigate which method of OA application (dribbling, fogging, or vaporizing) was the most effective at reducing V.

Modeling the Potential Global Distribution of Honeybee Pest, under Changing Climate.

Beekeeping is essential for the global food supply, yet honeybee health and hive numbers are increasingly threatened by habitat alteration, climate change, agrochemical overuse, pathogens, diseases, and insect pests. However, pests and diseases that have unknown spatial distribution and influences are blamed for diminishing honeybee colonies over the world. The greater wax moth (GWM), , is a pervasive pest of the honeybee, .

Genetic network analysis between subspecies based on mtDNA argues the purity of specimens from North Africa, the Levant and Saudi Arabia.

Objectives: This study aimed to analyze the genetic relationships between honey bee subspecies using reference specimens and recently collected specimens from different parts of the world. The purity of these specimens was discussed in light of the obtained results.

Methods: The genetic networks were constructed between 21 subspecies of honey bees, L.

Effects of sugar feeding supplemented with three plant extracts on some parameters of honey bee colonies.

Sugar feeding is crucial to bee colonies during periods without natural nectar resources. The health and the development of bee colonies are affected by the sugar feeding type. Also, some materials can be added to the sugar feeding to boost the ability of bee colonies to withstand parasites.

Exploring the non-coding regions in the mtDNA of some honey bee species and subspecies.

The sequence of the DNA contains coding and non-coding regions. The role of the non-coding regions is not known and is hypothesized to maintain the structure of the DNA. This study aimed to investigate the structure of the non-coding sequences in honey bees utilizing bioinformatics.

Utilizing bioinformatics to detect genetic similarities between African honey bee subspecies.

Various honey bees, especially subspecies , occur in Africa and are distribute across the continent. The genetic relationships and identical genetic characteristics between honey bee subspecies in Africa (African bee subspecies) have not been widely investigated using sequence analysis. On the other hand, bioinformatics are developed rapidly and have diverse applications.
