Invasive species may exploit a wide range of food sources, thereby fostering their success and hampering mitigation, but the actual degree opportunism is often unknown. The small hive beetle (SHB), Aethina tumida, parasite honeybee colonies endemic to sub-Saharan Africa. SHBs have now spread on all habitable continents can also infest other social bees. To date, possible role solitary bee nests as alternative hosts Similarly, flowers sources are not well understood. Here, we show that...
Here, we examined the in vitro effects of co-exposure to a pathogen and common neonicotinoid on honey bee larvae survival adult learning behavior following standard olfactory conditioning procedure based proboscis extension response paradigm. We exposed or co-exposed American foulbrood sub-lethal doses thiamethoxam (chronic exposure). Our results revealed no additive between two stressors larval mortality. However, present work provides first evidence impaired memory bees that were fed (0.6...
The sex ratio of sexually reproducing animal species tends to be 1:1, which is known as Fisher's principle. However, differential mortality and intraspecific competition during pupation can result in a biased adult insects. female-biased small hive beetles (SHBs) from both laboratory field studies, but the underlying reasons are not well understood. Here, we used mass individual test if between sexes and/or interactions explain this ratio. data show significant rearing, even when assuming...
Cuticular hydrocarbons (CHCs) cover insects’ bodies and play important roles in chemical communication, including nestmate recognition, for social insects. To enter colonies of a host species, parasites may acquire host-specific CHCs or covertly maintain their own CHC profile by lowering its quantity. However, the small hive beetles (SHBs), Aethina tumida, which are honey bee, Apis mellifera, colonies, other bee nests, is currently unknown. Here, adults SHB workers were collected from same...
Multiple mating by both sexes is common among sexually reproducing animals. Small hive beetles (SHB), Aethina tumida, are parasites of bee nests endemic to sub-Saharan Africa and have become a widespread invasive species. Despite the considerable economic damages they can cause, their basic biology remains poorly understood. Here we show that male female small mate multiple times, suggesting costs for low in this In an A. tumida population United States, combination laboratory experiments...
Abstract Small hive beetles (SHB), Aethina tumida , are free‐flying parasites, which actively seek and invade honeybee host colonies. Previous research suggests that SHB prefer colonies in the shade. Further, it has been stated any colony with equal impunity. Though, impact of aggressiveness on infestation levels never quantified. Here, we confirm significantly higher shaded further suggest aggression is minor importance only. In state Rio de Janeiro, Brazil, local Africanized at a sunny ( N...
Abstract Starvation resistance, or the ability to survive periods without food, can shed light on selection pressure imposed by food scarcity, including chances invade new regions as a result of human transport. Surprisingly, little information is known about starvation resistance for invasive insect species. Given that native and populations differ in this would suggest different scenarios adaptive shifts fostering invasion success. Here, we show striking differences adult small hive...
The small hive beetle (SHB), Aethina tumida, a parasite of honey bees is endemic to Sub-Saharan Africa and has become global invasive pest. Adequate surveillance methods based on trapping need testing verification their efficacy. We tested the efficacy top frame supplied cardboard traps. was extremely low (0.9%) significantly less effective than bottom board placed
