Objective: In recent years, there has been an increase in interest functional honey bee products. Due of their high nutritional content, drone larvae (Apilarnil) is capable a wide range biological activities. this study, we compared the individual and total weights obtained from colonies fed with different substitute foods.Material Methods: 12 out 100 comparable queen age, brood status colony s...
bee stings are commonly encountered worldwide. various manifestations after bee sting have been described including local reactions which are common, systemic responses such as anaphylaxis, diffuse intravascular coagulation and hemolysis. we report a case of a 74-year-old man who developed neurologic deficit 5 hours after bee stings, which was confirmed to be left frontal infarction on brain ct...
Flower pollen is collected by honeybee foragers, adhered on their rear legs and transported into the hives in the form of pellets. Once in the hives, bee pollen is moisturised with nectar and bee mouth secretions and due to enzymatically modifications it becomes the so-called bee-bread, the protein reservoir of young bees. Bee pollen can be artificially removed from bee legs and collected by us...
1. When the parasitic mite Varroa jumped species from the eastern to the western honey bee, millions of infested bee colonies died. Recent work has revealed that the probable cause of this collapse is that mites provide a new route of transmission, by acting as a vector, for certain bee viruses. 2. Using a mathematical model parameterized by recently collected data on bee viruses, we investigat...
Wild bee conservation is regarded as essential for sustainable production of pollinator-dependent crops, yet little is known about the effects on wild bee communities of typical insect pest management programs used postbloom. We developed an insecticide program risk (IPR) index to quantify the relative risk to wild bees of insecticide programs applied to blueberry fields. This was used to deter...
In the present study, the effects of low (10 ng/bee) and high (100 ng/bee) doses of acetamiprid and deltamethrin insecticides on multi-trial learning and retrieval were evaluated in the honey bee Apis mellifera. After oral application, acetamiprid and deltamethrin at the concentrations used were not able to impair learning sessions. When the retention tests were performed 1 h, 6 h, and 24 h aft...
