Comparison of Trap Collections and Cost of Commercially Available and Homemade Yellowjacket (Hymenoptera: Vespidae) Traps in Lake County, California.

J Econ Entomol 2021 Apr;114(2):868-874

Lake County Vector Control District, Esplanade, Lakeport, CA.

Yellowjackets are notable pests of humans due to their opportunistic foraging behaviors, painful stings, and potential for causing dangerous allergic reactions. Baited traps provide a useful supplement for controlling yellowjackets compared with nest treatments, which are often dangerous, time consuming, costly, and do little to prevent nuisance interactions between humans and foragers. This study compares three homemade yellowjacket traps and three commercially available traps in Lake County, California, to determine efficacy and cost benefit. Read More

Getting the Most Out of Your Zombie: Abdominal Sensors and Neural Manipulations Help Jewel Wasps Find the Roach's Weak Spot.

Brain Behav Evol 2020 30;95(3-4):181-202. Epub 2020 Oct 30.

Department of Biological Sciences, Vanderbilt University, Nashville, Tennessee, USA,

The parasitoid emerald jewel wasp (Ampulex compressa) subdues the American cockroach (Periplaneta americana) with a sting to the 1st thoracic ganglion, followed by a sting to the roach's brain, causing long-term pacification. The wasp then leads the cockroach to a hole where it lays an egg on the roach middle leg before barricading the entrance and departing. Although many aspects of the wasp's initial attack have been investigated, few studies have detailed the egg-laying process and the subsequent fate of the larvae. Read More

Sensitization to Hymenoptera venom in pollen allergic patients: Frequency and involvement of cross-reacting carbohydrate determinants (CCD).

PLoS One 2020 8;15(9):e0238740. Epub 2020 Sep 8.

Department of Rheumatology, Immunology and Allergology, Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland.

Sensitization to Hymenoptera venom in patients without a history of systemic allergic reactions to Hymenoptera stings is frequently found and can be due to the presence of specific IgE to cross-reactive carbohydrate determinants (CCD). This study investigates 105 pollen allergic subjects for the presence of specific IgE to honeybee or wasp venom, pollen, the MUXF3 carbohydrate epitope from bromelain and recombinant Hymenoptera venom components. In addition, in a subgroup of patients (n = 10) a basophil activation test (BAT) using bee and wasp venom was performed. Read More

Functional Profile of Antigen Specific CD4 T Cells in the Immune Response to Phospholipase A1 Allergen from Venom.

Toxins (Basel) 2020 06 8;12(6). Epub 2020 Jun 8.

Laboratory of Translational Immunology, Medicine School, FCM, University of Campinas (UNICAMP), Campinas 13083-888, Brazil.

Insect venom can cause systemic allergic reactions, including anaphylaxis. Improvements in diagnosis and venom immunotherapy (VIT) are based on a better understanding of an immunological response triggered by venom allergens. Previously, we demonstrated that the recombinant phospholipase A1 (rPoly p 1) from wasp venom induces specific IgE and IgG antibodies in sensitized mice, which recognized the native allergen.

Department of Dermatology and Dermatologic Surgery, Medical University of South Carolina, Charleston, USA.

The Hymenoptera order of insects includes Apidae (bees), Vespidae (wasps, yellow jackets, hornets), and Formicidae (fire ants). All 3 of these families of insects inject venom into their prey or as a defense mechanism via ovipositors in their abdomen. Three types of reactions can be seen after a vespid sting: uncomplicated local reactions, large local reactions, and systemic reactions (SRs). Read More

Case Rep Nephrol Dial 2019 Sep-Dec;9(3):137-148. Epub 2019 Nov 13.

Department of Child Health, Cipto Mangunkusumo Hospital, Faculty of Medicine Universitas Indonesia, Jakarta, Indonesia.

Multiple wasp stings may cause fatal complications, such as anaphylactic reactions, intravascular hemolysis, rhabdomyolysis, acute kidney injury (AKI), increased levels of liver enzymes, clotting abnormalities, or even death. AKI-related mortality due to multiple wasp stings may reach 25%, occurring within the early onset of disease; therefore, renal function should be continuously monitored within the first few days following the stings. Herein, we report 2 cases of AKI due to multiple stings of wasp (). Read More
