The discovery that some horned beetles (but not horned species only) exhibit collaboration between a male and a female in nestbuilding is remarkable, for such collaboration is almost unknown elsewhere among insects. Even in completely social insects such as the ants and bees the males take no ...
Female bees and wasps demonstrate, through their performance ofelaborate learning flights, when and where they memorise features ofa significant site. An important feature of these flights is that theinsects look back to fixate the site that they are leaving. Females,which forage for nectar and pol...
In subject area: Veterinary Science and Veterinary Medicine The product of the male accessory glands that serves as a transport medium for sperm and contains physiologically active substances that can affect the physiology of the female receiving it. ...
Exposure to stresses such as heat, cold and pesticides can have a greater negative impact on drones (males) compared to worker (female) honeybees, studies have shown. New research has come to light showing male honeybees are more ...
Female bees receive heterozygous CSD genes, whereas males receive only a single copy. That looks similar to the XO/ZO system, right? Well, here’s the twist. Unlike these systems, which receive autosomes from both parents, male honey bees andantsreceive chromosomes only from the female par...
Female bees visit flowers both to gather nectar for their own energetic needs and to gather the pollen on which their offspring will feed. Some bees are oligolectic, i.e., they are fairly restricted in the range of plant species from which they gather pollen. Others, such as the ...
Dr Stephan Wolf, lead author of the research, said: "Despite fundamental differences in the daily habits between male and female bees, this work illustrates that male bees can be clever shoppers in the flower supermarket even when their main interest is in mating." ...
The queens of eusocial bees, ants and wasps mate only during a very short period early in life and males therefore produce ejaculates consisting of large numbers of high quality sperm. Such extreme selection for high fecundity resulted in males investing
Age-related mushroom body expansion coincides with reproductive maturation in male bees, and may represent a common developmental change associated with dispersal from the nest prior to the onset of mating. A primary function of male Hymenoptera is to inseminate a female(s)17,33,34,35,36,37, ...
Provides information on a study assessing the relative importance of several floral traits, as well as microhabitat, in determining both the male and female pollination success in a nonrewarding orchid (Cypripedium acaule Ait.) in two Nova Scotia populations. Methodology used to conduct the study; ...
