The housefly is an object of biological research, partly for its variable sex-determination mechanism. Although a wide variety of sex-determination mechanisms exists in nature (e.g. male and female heterogamy, haplodiploidy, environmental factors), the way sex is determined is usually fixed within a species.
Z)-9-Tricosene, known as muscalure, is an insect pheromone found in dipteran flies such as the housefly. Females produce it to attract males to mate. Females produce it to attract males to mate. It is used as a pesticide , as in Maxforce Quickbayt by Bayer, luring males to traps to prevent them from reproducing.
The lesser house fly (Fannia canicularis) , commonly known as little house fly, is a species of fly. It is somewhat smaller (3.5–6 mm (0.14–0.24 in)) than the common housefly and is best known for its habit of entering buildings and flying in jagged patterns in the middle of a room.
Hydrotaea is a genus of insects in the housefly family, ... The average male Hydrotaea is 6.5-8.5 mm and the average female is 5.75-7.5 mm.
In the XY sex-determination system, the female-provided ovum contributes an X chromosome and the male-provided sperm contributes either an X chromosome or a Y chromosome, resulting in female (XX) or male (XY) offspring, respectively. Hormone levels in the male parent affect the sex ratio of sperm in humans. [25]
The males with superior detection and flying abilities are most likely to reach the female beetle first which leads to a selection for genetically-advantageous males. [6] In most species, pheromones are released by the non-limiting sex. Some female moths signal, but this is cheap and low risk; it means the male has to fly to her, taking a high ...
Lateral close-up of a male C. vomitoria. Blue bottle flies are typically 10–14 mm (3 ⁄ 8 – 9 ⁄ 16 in) long, almost twice the size of a housefly. The head and thorax are dull gray, and the back of the head has long yellow-orange setae. [5] [6] The abdomen is bright metallic blue with black markings. Its body and legs are covered with ...
Aedeagus of Pentodon idiota Photomicrograph of the aedeagus of water scavenger beetle Tormissus linsi (from above). An aedeagus (/ i ˈ d i. ə. ɡ ə s / or / i. d i ˈ eɪ. ɡ ə s / [1] [2] pl. aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.
