While the vast majority of wasps play no role in pollination, a few species can effectively transport pollen and pollinate several plant species. [42] Since wasps generally do not have a fur-like covering of soft hairs and a special body part for pollen storage (pollen basket) as some bees do, pollen does not stick to them well. [43]
Adult female wasps of most species oviposit into their hosts' bodies or eggs. More rarely, parasitoid wasps may use plant seeds as hosts, such as Torymus druparum. [5] Some also inject a mix of secretory products that paralyse the host or protect the egg from the host's immune system; these include polydnaviruses, ovarian proteins, and venom ...
The wasps that inhabit a particular tree can be divided into two groups; pollinating and non-pollinating. The pollinating wasps are part of an obligate nursery pollination mutualism with the fig tree, while the non-pollinating wasps feed off the plant without benefiting it. The life cycles of the two groups, however, are similar.
Legions of wasps, mostly tiny and unnoticed, ply their trade at the expense of inestimable numbers of caterpillars of moths and butterflies. Many tomato-growers have seen the fruits of an elfin ...
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas.Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it into a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host.
Adult hornets and their relatives (e.g., yellowjackets) feed themselves with nectar and sugar-rich plant foods. Thus, they can often be found feeding on the sap of oak trees, rotting sweet fruits, honey, and any sugar-containing foodstuffs. Hornets frequently fly into orchards to feed on overripe fruit, and tend to gnaw a hole in fruit to ...
They tend to be less conspicuous than the social (wasps) do,” Kimsey said, adding that they are “good to have around” to eat other bugs such as caterpillars. There are roughly 300 species of ...
The reproduction of gall wasps is usually partly parthenogenesis, in which a male is completely unnecessary, and partly two-sex propagation. [2] Most species have alternating generations, with one two-sex generation and one parthenogenic generation annually, whereas some species produce very few males and reproduce only by parthenogenesis, [2] possibly because of infection of the females ...
