We present a genome assembly from an individual female Emmelina monodactyla (the Common Plume; Arthropoda; Insecta; Lepidoptera; Pterophoridae). The sequence is 312 megabases in span. Most of the scaffolded into 30 chromosomal pseudomolecules, including assembled W and Z sex chromosomes. mitochondrial has also been 15.3 kilobases length. ...

A catalog of type specimens of Heteroptera (Insecta: Hemiptera) deposited in the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, Brazil, is presented and updated to May, 2012. A total of 37 holotypes and 61 lots of paratypes of 78 species are listed in their families: Miridae and Reduviidae (infraorder: Cimicomorpha); Mesoveliidae and Velfidae (Gerromorpha); Belostomatidae, Naucorid...

This review presents the main species of venomous and poisonous arthropods, with commentary on the clinical manifestations provoked by the toxins and therapeutic measures used to treat human envenomations. The groups of arthopods discussed include the class Arachnida (spiders and scorpions, which are responsible for many injuries reported worldwide, including Brazil); the subphylum Myriapoda, w...

The lice (Insecta: Phthiraptera) are permanent obligatory ectoparasite of a diverse selection of birds and mammals with a worldwide distribution. This study provides information on the lice species most commonly associated with peacock in Sistan, southeast Iran. There is no previous described study on lice infestation of peacock in Iran. For this aim, Peacock were examined carefully for chewing...

Burrows within black-tailed prairie dog (Cynomys ludovicianus) colonies on the Rocky Mountain Arsenal National Wildlife Refuge, Colorado, were dusted with deltamethrin insecticide to reduce flea (Insecta: Siphonaptera) abundance. Flea populations were monitored pre- and posttreatment by combing prairie dogs and collecting fleas from burrows. A single application of deltamethrin significantly re...

We report here the case of a metazoan parasite, a strepsipteran, that manipulates host epidermal tissue and wraps itself within it; which probably camouflages the endoparasite and is recognized as "self" by the host. This mechanism is one of immune avoidance among parasitoid insects. The host-derived epidermal "bag" might have enabled Strepsiptera to radiate to disparate hosts compared with the...

Marssoniella elegans Lemmermann, 1900, a parasite of ovarial tissues of the copepod Cyclops vicinus Uljanin, 1875, was studied as a representative of aquatic-clade microsporidia which form "heteroinfectious spores" (spores not infective to the original host as opposed to "homoinfectious spores" which are infective for the original host) and which thus should require an alternate host. Several s...
