Penaeus monodon, commonly known as the giant tiger prawn, [1] [2] Asian tiger shrimp, [3] [4] black tiger shrimp, [5] [6] and other names, is a marine crustacean that is widely reared for food. Tiger prawns displayed in a supermarket
Feeding experiments show that P. monodon post-larvae can be infected by the HPV carried by Artemia, which implies the risk of rearing system contamination. [17] Parents-offspring transmissions are both reported by aquaculture farms in China and India, confirming the vertical transmission of HPV. [18] [19]
William Elford Leach erected the genus Megalopa in 1813 for a post-larval crab; a copepod post-larva is called a copepodite; a barnacle post-larva is called a cypris; a shrimp post-larva is called a parva; a hermit crab post-larva is called a glaucothoe; a spiny lobster / furry lobsters post-larva is called a puerulus and a slipper lobster post ...
Larvae are the feeding and growing stages and periodically undergo hormone-induced ecdysis, developing further with each instar, until they undergo the final larval–pupal moult. The larvae of many lepidopteran species will either make a spun casing of silk called a cocoon and pupate inside it, or will pupate in a cell under the ground.
From these eggs hatch zoeae, the first larval stage of crustaceans. They go through several larval stages in brackish water before metamorphosing into postlarvae, at which stage they are 0.28–0.39 in (7.1–9.9 mm) long and resemble adults. [5] This metamorphosis usually takes place about 32 to 35 days after hatching. [5]
The "arms" or tubercles can fall off without harming the caterpillar, aiding the larva in defense. The larvae are 1.5–2.5 centimetres (0.59–0.98 in) in length. [1] [2] It is solitary and is not a very significant agricultural threat, but it is a common sight in orchards.
Forensic entomological decomposition is how insects decompose and what that means for timing and information in criminal investigations.Medicolegal entomology is a branch of forensic entomology that applies the study of insects to criminal investigations, and is commonly used in death investigations for estimating the post-mortem interval (PMI).
Indoxacarb is an oxadiazine pesticide developed by DuPont that acts against lepidopteran larvae. [1] It is marketed under the names Indoxacarb Technical Insecticide, Steward Insecticide and Avaunt Insecticide. It is also used as the active ingredient in the Syngenta line of commercial pesticides: Advion and Arilon. [2] [3] [4]
