Pest Alert: Brown Marmorated Stink Bug Halyomorpha Halys
OREGON DEPARTMENT OF AGRICULTURE FACT SHEETS AND PEST ALERTS Pest Alert: Brown Marmorated Stink Bug Halyomorpha halys Introduction Brown Marmorated Stink Bug The brown marmorated stink bug (BMSB), Halyomorpha adult nymph newly-hatched halys, is an Asian species first detected in North America nymphs in Pennsylvania in 1996, and in Oregon in 2004. BMSB has since been detected in 43 states. In Oregon it is es- tablished statewide, in the western region from Portland to Ashland, and in the north east to Hood River. More recently it has been found in coastal counties and is likely still expanding its range and increasing in abundance around Oregon. A threat to Oregon agriculture BMSB is a major agricultural pest in Asia, attacking many crops. It is a significant agricultural pest in the Mid-At- lantic states of the U.S., attacking tree fruits, peppers, tomatoes, corn, berries, grapes, soybeans, melons, and even damaging young trees by feeding through the bark. BMSB is known to feed on over 170 species of plants. The insect threatens an estimated $21 billion worth of crops in the United States alone. Some commercial agri- cultural damage by BMSB has been reported in Oregon. Some home gardeners have reported extensive damage to beans, cucumbers, raspberries, hops, and several species A brown marmorated stink bug feeding on a mature hazelnut.

Boxelder Bug
BOXELDER BUG Integrated Pest Management for Home Gardeners and Landscape Professionals The western boxelder bug (Boisea rubrolineata) is often a nuisance pest around and in homes. Boxelder bugs usually feed on the leaves, flowers, and seedpods of the female or seedbearing box elder tree (Acer negundo), although they may also subsist on male box elder trees and occasionally occur on maple and ash trees. They may feed on the fruits of almond, apple, cherry, peach, Figure 1. Boxelder bug adult and nymphs. Figure 2. Young nymph of western box- pear, and plum trees, and on grapes, (J. K. Clark) elder bug, Boisea rubrolineata. where their feeding punctures cause (J. K. Clark) the fruit to become deformed. Large numbers of the bug usually occur only on female box elder trees. IDENTIFICATION When full grown, the boxelder bug is about 1/2 inch long and one-third as wide. Adults are mostly black and have three red lines on the pronotum of the thorax (one down the middle and on each margin) and several fine Figure 3. Boxelder bug eggs on leaf. Figure 4. Adult squash bug. red lines on each wing (Figure 1). The (J. K. Clark) (J. K. Clark) wings lie flat on the bug’s back when it is at rest. The abdomen is red. The young nymphs are bright red (Figure 2) and when approaching adulthood, become marked with black and begin to develop black wing pads. Eggs are yellow when first laid but become red as nymphs develop inside (Figure 3). Boxelder bugs are true bugs (Order: Hemiptera) in the family Rhopalidae. -

FILE COPY 161 Overwintering Aggregation of Boisea rubrolineatus (Heteroptera: Rhopalidae) in Western Oregon T. D. SCHOWALTER Department of Entomology, Oregon State University, Corvallis, Oregon 97331 Environ. Entomol. 15: 1055-1056 (1986) ABSTRACT Overwintering behavior of Boisea rubrolineatus (Barber) was studied during 1984-85. Large numbers of this insect aggregated on a single, large Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, tree, with deep bark fissures, at the edge of a stand ca. 1 km from a grove of maples, Acer macrophyllum Pursh, the feeding host. Other trees near the over- wintering site were smaller and lacked deep bark fissures, or were shaded by trees along the edge of the stand. Density measurement was used to estimate number of overwintering insects at ca. 8,000. These results demonstrate the degree of aggregative behavior in this insect and suggest that aspects of stand structure influence the availability of suitable over- wintering sites. KEY WORDS Boisea rubrolineatus, population dynamics, forest structure, resource uti- lization, overwintering site selection THE SURVIVAL OF overwintering adults of several pies, Acer macrophyllum Pursh, ca. 1 km N of the forest insect species may be critical to population overwintering site. These maples are the major trends and economic impacts (Furniss Carolin feeding host of this insect (Furniss Carolin 1977) 1977, Schowalter et al. 1986).

This publication will help you understand both the seasonal biology of boxelder bugs in Idaho, and landscape features that increase pest prob- lems. We discuss the relative importance of these insects as pests. Practical steps you can take to reduce nuisance problems include alternatives to insecticides and safe, effective insecticide use. Identification Boxelder bugs develop through three life stages: eggs, nymphs, and adults. Figure 1 shows the actual body sizes of a newly hatched nymph and a mature adult. Adults are the most commonly encountered life Figure 2. Adult boxelder bugs, Boisea trivittata, are stage.

The external morphology of eggs and manner of oviposition of three rhopalid species, Brachycarenus tigrinus (Schilling, 1829), Chorosoma schillingi (Schilling, 1829) and Rhopalus (Aeschyntelus) maculatus (Fieber, 1837) are described. The eggs were studied using Scanning Electron Microscopy (SEM), and the results complete previous observations.The emphasis of the study is on the characteristics of eggs and details of oviposition in representatives of the family Rhopalidae. The chorionic origin of attachment stalk was confi rmed only in the Chorosomatini. A completely smooth egg chorion was recognized in R. (A.) maculatus, as a unique condition within at least the Pentatomomorpha. Key words. Rhopalidae, Rhopalini, Chorosomatini, Brachycarenus tigrinus, Cho- rosoma schillingi, Rhopalus (Aeschyntelus) maculatus, egg structure, micropylar processes, chorion, attachment stalk, oviposition Introduction Heteroptera eggs have a stable shape due to a sclerotized chorion. Egg morphology is helpful for taxonomic and phylogenetic purposes. The morphology of heteropteran eggs varies distinctly among taxa; for details see two monographs: SOUTHWOOD (1956) and COB- BEN (1968). Both authors mentioned that the eggs of the coreoid family Rhopalidae have a specifi c morphological pattern (e.g. two micropylar processes). COBBEN (1968) not only compared the morphology of heteropteran eggs but made phylogenetic inferences from their important characters. -

A Guide to Arthropods Bandelier National Monument
A Guide to Arthropods Bandelier National Monument Top left: Melanoplus akinus Top right: Vanessa cardui Bottom left: Elodes sp. Bottom right: Wolf Spider (Family Lycosidae) by David Lightfoot Compiled by Theresa Murphy Nov 2012 In collaboration with Collin Haffey, Craig Allen, David Lightfoot, Sandra Brantley and Kay Beeley WHAT ARE ARTHROPODS? And why are they important? What’s the difference between Arthropods and Insects? Most of this guide is comprised of insects. These are animals that have three body segments- head, thorax, and abdomen, three pairs of legs, and usually have wings, although there are several wingless forms of insects. Insects are of the Class Insecta and they make up the largest class of the phylum called Arthropoda (arthropods). However, the phylum Arthopoda includes other groups as well including Crustacea (crabs, lobsters, shrimps, barnacles, etc.), Myriapoda (millipedes, centipedes, etc.) and Arachnida (scorpions, king crabs, spiders, mites, ticks, etc.). Arthropods including insects and all other animals in this phylum are characterized as animals with a tough outer exoskeleton or body-shell and flexible jointed limbs that allow the animal to move. Although this guide is comprised mostly of insects, some members of the Myriapoda and Arachnida can also be found here. Remember they are all arthropods but only some of them are true ‘insects’. Entomologist - A scientist who focuses on the study of insects! What’s bugging entomologists? Although we tend to call all insects ‘bugs’ according to entomology a ‘true bug’ must be of the Order Hemiptera. So what exactly makes an insect a bug? Insects in the order Hemiptera have sucking, beak-like mouthparts, which are tucked under their “chin” when Metallic Green Bee (Agapostemon sp.) not in use. -
Boxelder Bug Boisea Trivittata (Say); Family: Rhopalidae
IDL INSECT DIAGNOSTIC LABORATORY Cornell University, Dept. of Entomology, 2144 Comstock Hall, Ithaca NY 14853-2601 Boxelder Bug Boisea trivittata (Say); Family: Rhopalidae Boxelder bug (adult); actual size about 1/2 inch long. Photo © 2012 by Jason J. Dombroskie. Injury The boxelder bug may be a pest of outdoor trees as well as a household nuisance. It is the latter that is of most concern to homeowners. The bugs overwinter as adults and nymphs in protected dry places, often in wall voids or attics of houses and buildings. During warm days in the fall and again in the spring, the bugs become active and invade homes, creating a nuisance. They do not feed while indoors. Description The adult boxelder bug is about 1/2 inch in length, and brownish-black in color, with red stripes on the thorax and wing margins. The body is also bright red. Eggs are straw-yellow to rusty-red in color and are not often seen, as they are deposited on boxelder trees (Acer negundo) or other maples, or near the trees. The nymphs, which are found on the trees, are bright red in color with the front half darker. Nymphs resemble adults but do not have fully developed wings and are not able to reproduce. The change from nymph to adult is a gradual one. Life History The boxelder bugs pass the winter in the adult and sometimes nymphal stages in dry, sheltered places where they have accumulated in gregarious masses. They often choose buildings or houses as a protected place to overwinter. When weather warms up in the spring, the bugs leave their places of hibernation to fly to boxelder trees, where they deposit their eggs. -

Investigations of Posible Chemical and Acoustic
PEAR PEST MANAGEMENT RESEARCH FUND PROJECT REPORT: 2006 Title: Investigations of Possible Chemical and Acoustic Communication in Boxelder Bug, Leptocoris (=Boisea) spp. (Hemiptera: Rhopalidae) Principal Investigator: Jocelyn G. Millar, Professor, Dept. of Entomology, University of California, Riverside CA 92521. FAX: 951 827 3086. Email: [email protected] Cooperator: Lucia Varella, IPM Advisor, North Coast Abstract: Box elder bugs proved to be easy to maintain and lived a long time in the laboratory as adults, but it was remarkably difficult to induce the adults to break reproductive diapause. We found no evidence of acoustic or vibrational signals being used for communication. However, male bugs were strongly attracted to odors of live males or females in two-choice Y-tube olfactometer bioassays; females appeared to be less strongly attracted. Bioassays using live bugs in cages were not successful: the test bugs simply aggregated at the top of the cage. The profile of odors collected from males and females appeared to be similar, and the antennae of males and females showed the same pattern of relatively weak responses to components in the odor extracts. Thus, the formation of the aggregations of bugs seen in the field and in the laboratory may be mediated by species-specific but not sex-specific blends of insect-produced odors. The detailed analysis and reconstruction of these blends will be the focus of work in the coming year. Introduction: Boxelder bugs (Leptocoris or Boisea spp.) are chronic pests of pears in some parts of California, particularly near riparian areas (Anonymous 1991). These insects tend to be found in clumped distributions in the field, and they are well known from their large, overwintering aggregations, in which they often invade houses and create a nuisance for homeowners. -

McPherson: An Overview of the Heteroptera of Illinois 1989 THE GREAT LAKES ENTOMOLOGIST 177 AN OVERVIEW OF THE HETEROPTERA OF ILLINOIS l J. E. McPherson ,2 ABSTRACT A key to adults of all heteropteran families known to occur in Illinois is presented together with general information on the biologies of these families. Also included are general references on Heteroptera and on individual families, particularly if those references involve studies of fauna that were conducted in Illinois, adjacent states, or nearby parts of Canada. The Heteroptera (true bugs) is a large insect order that occurs worldwide and is represented in America north of Mexico by about 45 families. Of these, 36 are known to occur in Illinois. The order is a well defined group characterized by (1) a segmented beak that arises from the front of the head and (2) wings that, when present and well developed, lie flat on the abdomen with the first pair usually leathery basally and membranous distally.
