Extraction and Elemental Composition of Meconium in Polistes dominulus (Hymenoptera: Vespidae) [PDF]

open access: goldFlorida Entomologist, 2020
In the social wasps, meconium is the fecal waste of the last larval instar before pupation. Meconium is ejected from fifth (last) instar larvae after their last feeding period as a fecal mass in Polistes species. The ejection of the meconium is important for the completion of metamorphosis.

Circulating hemocytes from larvae of the paper wasp Polistes dominulus (Hymenoptera, Vespidae)

open access: greenTissue and Cell, 2007
Circulating hemocytes from larval stages of the paper wasp Polistes dominulus were characterized by light and transmission electron microscopy. Three types were identified: prohemocytes, plasmatocytes and granulocytes. The first two are agranular cells while the latter present typical cytoplasmic inclusions called granules.

Allergy to stings and bites from rare or locally important arthropods: Worldwide distribution, available diagnostics and treatment

open access: yesAllergy, Volume 78, Issue 8, Page 2089-2108, August 2023., 2023
Abstract Insect venom allergy is the most frequent cause of anaphylaxis in Europe and possibly worldwide. The majority of systemic allergic reactions after insect stings are caused by Hymenoptera, and among these, vespid genera induce most of the systemic sting reactions (SSR). Honey bees are the second leading cause of SSR.

Revisiting the hymenopteran diploid male vortex: a review of avoidance mechanisms and incidence

open access: yesEntomologia Experimentalis et Applicata, Volume 170, Issue 12, Page 1010-1031, December 2022., 2022
The Hymenoptera (bees, ants, wasps, and sawflies) have haploid males and diploid females. According to the diploid male vortex (DMV) theory, inbreeding increases sterile diploid male production and extinction risk for many species. We reviewed DMV incidence and avoidance.
