| By contrast, mutant hermaphrodites are self-sterile when unmated due to a failure in spermatid activation. |
|
| However, such unmated workers can produce either males or females parthenogenetically. |
|
| Smaller groups usually consist of an unmated female courted by unmated males. |
|
| Many male pigeons perform display flights in and near the territory to attract unmated females. |
|
| Separate or fixed covers protect contacts when not in use or while unmated. |
|
| In thelytoky, which occurs in many species of the suborder Symphyta, unmated females produce males. |
|
| The distribution of eggs was similar between the two species, and between mated and unmated females. |
|
| Female moths that remain unmated cannot produce and lay fertile eggs, therefore, damage from the subsequent generation of budworms is reduced. |
|
| In the dawn chorus, however, singing activity showed a similar seasonal pattern in mated and unmated males and was high until late stages of the breeding cycle. |
|
| These pheromones were taken by hexane extracts from wholes bodies and thoraces of unmated females. |
|
| In deuterotoky, unmated females of some Symphyta produce females as well as males. |
|
| Sealing caps are also available to maintain the IP rating of unmated connectors. |
|
| There was no predation and there were no unmated males in our population. |
|
| With an otherwise black connector the coloured contact insert and matching cable gland nut give a quick and easy method of identification, whether the connectors are mated or unmated. |
|
| It is stated that studies are under way to determine whether transmission of pinewood nematode dispersal juveniles is possible through oviposition wounds made by unmated Monochamus females. |
|
| Face flies hibernate in large numbers as unmated adults in buildings, mammal burrows, and in other protected places, whether heated or not. |
|
| The building of the nest is initiated by the unmated male while displaying to females. |
|
| The authors concluded that the abundant egg laying capacity of unmated Monochamus females could have implications for the introduction of B. xylophilus. |
|
| For applications requiring exposure to pressure, vacuum, liquids or steam, we provide hermetically sealed connectors, which remain sealed mated or unmated. |
|
| These beneficiaries of international surrogacy include same-sex couples, infertile opposite-sex couples, and unmarried or unmated individuals. |
|
|
|
| Some of the young females return, still unmated, from the nuptial flight. |
|
| We offer clients superior intellectual capital, extensive industry relationships and unmated execution capabilities. |
|
| Today's modern medical devices require connectivity that can be easily mated and unmated without damaging the circuit boards. |
|
| Since the connectors will likely be mated and unmated by a patient they must be easy to use and safe. |
|
| Being unmated and not mothering was not part of her initial plan. |
|
| Unmated males start nest construction and call particularly frequently to attract females. |
