However, they are not effective at killing biting insects (female mosquitoes and other insects) outdoors, [4] [5] being much more effective at attracting and killing other harmless and beneficial insects. A study by the University of Delaware showed that over a period of 15 summer nights, 13,789 insects were killed among six devices.
Drosophila melanogaster is a species of fly (an insect of the order Diptera) in the family Drosophilidae.The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the "vinegar fly", "pomace fly", [a] [5] or "banana fly". [6]
An insect growth regulator (IGR) is a chemical insecticide that kills insects indirectly by disrupting their life cycles. [1] The term was initially proposed to describe the effects of juvenile hormone analogs. [2] Although the term "insect growth disruptor" more accurately describes the actions of IGRs, it did not become widely used. [1]
A typical flyswatter. A flyswatter (or fly-swat, fly swatter [1]) usually consists of a small rectangular or round sheet of a lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh) around 10 cm (4 in) across, attached to a handle about 30 to 60 cm (1 to 2 ft) long made of a lightweight material such as wire, wood, plastic, or metal.
The wingspan is generally about 1.0 to 6.5 cm (1 ⁄ 2 to 2 + 1 ⁄ 2 in), though some species of Holorusia can reach 11 cm (4 + 1 ⁄ 4 in). [15] The antennae have up to 19 segments. [ 7 ] It is also characterized by a V-shaped suture or groove on the back of the thorax (mesonotum) and by its wing venation. [ 10 ]
The adult western house martin is 13 cm (5 in) long, with a wingspan of 26–29 cm (10– 11 + 1 ⁄ 2 in) and a weight averaging 18.3 g (21 ⁄ 32 oz). It is steel-blue above with a white rump, and white underparts, including the underwings; even its short legs have white downy feathering.
The eggs are white and are about 1.2 mm (1 ⁄ 16 in) in length, and they are deposited by the fly in a suitable place, usually dead and decaying organic matter, such as food waste, carrion, or feces. Within a day, larvae hatch from the eggs; they live and feed where they were
Here E is the Young's modulus for resilin, which has been measured to be 1.8×10 7 dyn/cm 2. Typically in an insect the size of a bee, the volume of the resilin may be equivalent to a cylinder 2×10 −2 cm long and 4×10 −4 cm 2 in area. In the example given, the length of the resilin rod is increased by 50% when stretched.
