Ovipositor of long-horned grasshopper (the two cerci are also visible). The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs.In insects, an ovipositor consists of a maximum of three pairs of appendages.
The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body.
The female moths oviposit around 2000 eggs during their adult lifetime. The eggs are randomly laid on the forest floor. [9] The eggs are initially yellow-white, and darken to black, before hatching (normally after about 2 weeks). [6] Initially the larva live under decaying wood close to the ground where they feed on bracket fungi. [6]
They often select natural orifices or wet fur, though they do not tend to oviposit in wounds, as is mistakenly thought by many. [13] Gravid L. sericata females prefer warm temperatures for their offspring, since this decreases development time, so increases survival, and they oviposit faster and with more eggs in warmer carrion.
For some agricultural pests manufactured sex pheromones are placed in traps to capture adults before they can oviposit (lay their eggs) leading to the hatching of their destructive larvae. [3] While there are thousands of chemicals insects can detect there is a limited range that insects use as cues to move towards or away from the source of ...
T. intermedia employs superficial oviposition, meaning that the yucca moth lays its eggs very slightly beneath the plant tissue, so as not to damage the yucca ovule. This strategy allows the moth to bypass the yucca plant's regulation of the number of eggs it hosts, leading to exploitation of the plant. [ 4 ]
Aedes japonicus are multivoltine and oviposit 2 – 3 times per gonotrophic cycle, producing a mean of 114 ± 51 eggs per female. [13] The eggs are resistant to desiccation and if temperatures are low then the eggs will enter the prediapause stage where its responsive to environmental based cues that cause it to enter diapause at the pharate ...
A female can oviposit five to seven eggs per day and A. eugenii females display a mean fecundity of 341 eggs per lifetime. [2] Eggs are pearl-shaped and range from 0.3 to 0.4 millimetres in diameter [4] and the egg stage lasts for approximately 4.3 days. [2]
