Hepatopancreatic parvoviruses (HPV) are icosahedral particles with an average 22 nm diameter, [4] whose genomes consist of negative single-stranded DNA molecules. [4] Four complete genome sequences of HPV are available to date: [1] Thailand (Penaeus monodon densovirus (PmoDNV)), [5] Australia (Penaeus merguiensis densovirus (PmeDNV)), [6] India (Penaeus monodon densovirus (PmoDNV) [7] and ...
The adult cottonwood borer is a large longhorn beetle with a black-and-white coloration and black antennae as long or longer than the body. [5] The white portions are due to microscopic masses of hair. [6] The larvae have legless, cylindrical, creamy-white bodies with a brown-to-black head and grow up to 38 millimetres (1.5 in) long.
The larvae have six legs, with two pointy projections toward the caudal end. Finally, the pupal stage (a cocoon-like form) is usually a white or brownish color. The beetle life cycle lasts about three years or more, with the larval stage ranging anywhere from 20 to over 100 days, and the pupal stage around eight days.
The larva of the black larder beetle has less strongly curved appendages. Mature larvae of both species tend to bore into hard substrates such as wood, cork, and plaster to pupate. [4] Adult larder beetles are generally 1/3 to 3/8 of an inch long and are dark brown with a broad, pale yellow spotted band across the upper portion of the elytra ...
If borer infestation symptoms are detected, pest control such as fumigation and heating often represent safe alternatives. [16] Biological control is another way to keep borer populations in check. Notably, Clerid beetles prey on borers in boring tunnels. [9] These predators feed on the bamboo borers eggs, larvae, pupae, and sometimes adults.
The family Scraptiidae is a small group of tenebrionoid beetles sometimes called false flower beetles. There are about 400 species in 30 genera with a world-wide distribution. The adults are found on flowers, sometimes in large numbers, [1] but are also found on foliage. The larvae are typically found under the bark of dead trees. [2]
Lymexylidae larvae have a symbiotic association with certain types of fungi. The fungi grow in sheltered environments where they are tended by the larvae, such as the holes burrowed into the wood and, in return, the larvae feed on the fungi. [3] Elateroides dermestoides lays eggs into boreholes of bark beetles on a fallen beech
Consistent with other members of the family Asilidae, larvae are thought to be predaceous, feeding on soft-bodied insects in the soil. [7] In terms of aggressive mimicry, the female flies of M. bomboides may enter into bumblebee nests to lay eggs. [7] Due to their mimetic resemblance, M. bomboides females could then escape recognition and ...
