Efforts to develop formulas for contrasting genetic interests of workers and queens in social Hymenoptera are complicated by many factors, including multiple matings by queens, oviposition by unmated females, and mating rivalry among genetic relatives (Hamilton's "local mate competition"). Because of haplodiploid sex determination in Hymenoptera, when such influences are absent, queens benefit ...

PURPOSE OF REVIEW Wine contains chemical and biological contaminants. Symptoms such as facial flushing, asthma and oral allergic swelling and burning (oral syndrome) have been attributed to these contaminants and food additives. Their clinical implications should be known. RECENT FINDINGS Recent studies have reported a high prevalence of hypersensitivity symptoms after intake of alcoholic dri...

Background and Objective. Various venom immunotherapy (VIT) protocols are available for Hymenoptera allergy. Although adverse reactions (ADRs) to VIT are widely reported, controlled trials are still needed. We conducted a randomized prospective study to evaluate ADRs and the efficacy of three VIT regimens. Methods. 76 patients with Hymenoptera allergy, aged 16-76 years, were randomized to recei...

Severe allergic reactions during specific immunotherapy may occur in the treatment of hymenoptera sting allergy. The objective of the present study was to examine the characteristics of allergic reactions during specific immunotherapy in patients with allergy towards hymenoptera venom in the Iranian population. A prospective study was performed using the clinical reports of 27 patients with ana...

Objective: The aim of this study was to analyze current evidence regarding allergy to Hymenoptera venoms. Brief review: The Hymenoptera species, which are most important in the context of venom allergy, include the common wasp (Vespula vulgaris), German wasp (Vespula germanica), and the honey bee (Apis mellifera). Depending on the population, systemic allergic reactions occur in 1.5–8.9% of cas...

Most reports published in the field of forensic entomology are focused on Diptera and neglect the Hymenoptera community. However, Hymenoptera are part of the entomofaunal colonization of a dead body. The use of Hymenoptera parasitoids in forensic entomology can be relevant to evaluate the time of death. Hymenoptera parasitoids of the larvae and pupae of flies may play an important role in the e...

INTRODUCTION From the literature, patients with a history of anaphylaxis to hymenoptera venom and positive specific IgE have shown a correlation between elevated tryptase levels and two clinical situations: systemic mastocytosis and an increased risk of reactions to venom immunotherapy or hymenoptera sting. Other clinical scenarios could explain elevated tryptase levels. MATERIAL AND METHODS ...

Aprostocetus exertus La Salle (Hymenoptera: Eulophidae: Tetrastichinae) is described as a parasitoid of the invasive Erythrina Gall Wasp, Quadrastichus erythrinae Kim (Hymenoptera: Eulophidae: Tetrastichinae). The description is based on material originally collected in Tanzania and South Africa. This species is described because of its potential as a biological control agent against the Erythr...

We are reporting here a rare case of Parkinsonism (Hypokinetic dysarthria) caused after a bee stung, a member of the hymenoptera order. The main aim of this report is to orient the clinicians with the possibility of extrapyramidal syndromes because of hymenoptera stings.
