All of the pest information to take the shorter, more direct route ants use odor trails for orientation, but these trails home.

These recruited all vary from one ant species to the next. In fire ants, ants will follow the odor trail directly to the food the trail chemical is produced by the Dufour's gland, source. In turn, each ant will reinforce the odor trail which is named after its discoverer, Dufour, and is until the food is gone. This behavior is a highly laid down by the stinger. This pheromone is made up efficient means of exploiting a temporary food of molecules which evaporate very quickly. Thus, the resource. fire ant's odor trail is very short-lived. -

A Saliva Protein of Varroa Mites Contributes to the Toxicity Toward Apis Cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A
www.nature.com/scientificreports OPEN A Saliva Protein of Varroa Mites Contributes to the Toxicity toward Apis cerana and the DWV Elevation Received: 10 August 2017 Accepted: 9 February 2018 in A. mellifera Published: xx xx xxxx Yi Zhang & Richou Han Varroa destructor mites express strong avoidance of the Apis cerana worker brood in the feld. The molecular mechanism for this phenomenon remains unknown. We identifed a Varroa toxic protein (VTP), which exhibited toxic activity toward A. cerana worker larvae, in the saliva of these mites, and expressed VTP in an Escherichia coli system. We further demonstrated that recombinant VTP killed A. cerana worker larvae and pupae in the absence of deformed-wing virus (DWV) but was not toxic to A. cerana worker adults and drones. The recombinant VTP was safe for A. mellifera individuals, but resulted in elevated DWV titers and the subsequent development of deformed-wing adults. RNAi- mediated suppression of vtp gene expression in the mites partially protected A. cerana larvae. We propose a modifed mechanism for Varroa mite avoidance of worker brood, due to mutual destruction stress, including the worker larvae blocking Varroa mite reproduction and Varroa mites killing worker larvae by the saliva toxin. The discovery of VTP should provide a better understanding of Varroa pathogenesis, facilitate host-parasite mechanism research and allow the development of efective methods to control these harmful mites. Varroa destructor Anderson & Trueman (Acari: Varroidae) was originally identifed as an ectoparasite of the Asian honeybee Apis cerana. Before the year 2000, V. destructor was miscalled V. jacobsoni. In fact, these two species are diferent in body shape, cytochrome oxidase (CO-I) gene sequence, and virulence to honey bees1. -
Wisconsin Bee Identification Guide
WisconsinWisconsin BeeBee IdentificationIdentification GuideGuide Developed by Patrick Liesch, Christy Stewart, and Christine Wen Honey Bee (Apis mellifera) The honey bee is perhaps our best-known pollinator. Honey bees are not native to North America and were brought over with early settlers. Honey bees are mid-sized bees (~ ½ inch long) and have brownish bodies with bands of pale hairs on the abdomen. Honey bees are unique with their social behavior, living together year-round as a colony consisting of thousands of individuals. Honey bees forage on a wide variety of plants and their colonies can be useful in agricultural settings for their pollination services. Honey bees are our only bee that produces honey, which they use as a food source for the colony during the winter months. In many cases, the honey bees you encounter may be from a local beekeeper’s hive. Occasionally, wild honey bee colonies can become established in cavities in hollow trees and similar settings. Photo by Christy Stewart Bumble bees (Bombus sp.) Bumble bees are some of our most recognizable bees. They are amongst our largest bees and can be close to 1 inch long, although many species are between ½ inch and ¾ inch long. There are ~20 species of bumble bees in Wisconsin and most have a robust, fuzzy appearance. Bumble bees tend to be very hairy and have black bodies with patches of yellow or orange depending on the species. Bumble bees are a type of social bee Bombus rufocinctus and live in small colonies consisting of dozens to a few hundred workers. Photo by Christy Stewart Their nests tend to be constructed in preexisting underground cavities, such as former chipmunk or rabbit burrows. -

Evidence for and Against Deformed Wing Virus Spillover from Honey Bees to Bumble Bees: a Reverse Genetic Analysis Olesya N
www.nature.com/scientificreports OPEN Evidence for and against deformed wing virus spillover from honey bees to bumble bees: a reverse genetic analysis Olesya N. Gusachenko1*, Luke Woodford1, Katharin Balbirnie‑Cumming1, Eugene V. Ryabov2 & David J. Evans1* Deformed wing virus (DWV) is a persistent pathogen of European honey bees and the major contributor to overwintering colony losses. The prevalence of DWV in honey bees has led to signifcant concerns about spillover of the virus to other pollinating species. Bumble bees are both a major group of wild and commercially‑reared pollinators. Several studies have reported pathogen spillover of DWV from honey bees to bumble bees, but evidence of a sustained viral infection characterized by virus replication and accumulation has yet to be demonstrated. Here we investigate the infectivity and transmission of DWV in bumble bees using the buf-tailed bumble bee Bombus terrestris as a model. We apply a reverse genetics approach combined with controlled laboratory conditions to detect and monitor DWV infection. A novel reverse genetics system for three representative DWV variants, including the two master variants of DWV—type A and B—was used. Our results directly confrm DWV replication in bumble bees but also demonstrate striking resistance to infection by certain transmission routes. Bumble bees may support DWV replication but it is not clear how infection could occur under natural environmental conditions. Deformed wing virus (DWV) is a widely established pathogen of the European honey bee, Apis mellifera. In synergistic action with its vector—the parasitic mite Varroa destructor—it has had a devastating impact on the health of honey bee colonies globally1,2. -

Argentine Ant, Liniepithema Humile Mayr (Hymenoptera: Formicidae)
FDACS-P-01684 Pest Alert created 20-April-2009 Florida Department of Agriculture and Consumer Services, Division of Plant Industry Charles H. Bronson, Commissioner of Agriculture Argentine Ant, Liniepithema humile Mayr (Hymenoptera: Formicidae) David Westervelt, [email protected], Apiary Inspector and Researcher, Florida Department of Agriculture and Consumer Services, Division of Plant Industry Eric T. Jameson, [email protected], Apiary Inspector, Florida Department of Agriculture and Consumer Services, Division of Plant Industry INTRODUCTION: The Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae), was introduced into Louisiana in 1890 on coffee ships from Brazil. It has since spread to most of the southern United States where it has become a nuisance pest in the urban environment. It can and does disrupt ecosystems by directly displacing other ant species and other insects. Argentine ants utilize a wide variety of food sources that include protein (live or dead insects) and substances rich in sugars such as honeydew secretions from aphids. Foraging worker ants will also search for food indoors. Argentine ants form large colonies that can include numerous nesting sites that can cover a large area. The Argentine ant can be a serious pest of commercial honey bee hives. This ant challenges the front entrance of the bee hive causing the European honey bee (EHB), Apis mellifera Linnaeus, to guard it. The ants then invade the colony in large numbers through the top or other unguarded openings in the hive (Fig. 1), causing the EHB to abscond, abandoning the honey and brood for the ants to take back to their nest. -
