Four of five strains tested clearly showed staining specifically in the dorsal compartment of the wing disc, as expected for apterous expression. |
|
Importantly, sexual selection favors apterous males in several natural populations of a water strider species. |
|
Prey items were separated into morphotypes based on order, life stage, and in the case of Hymenoptera, apterous or winged. |
|
The presence of a fundatrix, the numbers of soldiers, nonsoldier nymphs, apterous adults, and alates were recorded. |
|
A survey conducted in 2005-2006 found the apterous form of this thrips infesting several types of ornamental bulbs around the country. |
|
The ratio of alate to apterous adults indicated that relatively higher numbers of alates were found in the control areas. |
|
However, females are not a problem, because they are apterous or micropterous in Embolemus and macropterous in Ampulicomorpha. |
