Rainfall and Parasitic Wasp (Hymenoptera: Ichneumonoidea
Agricultural and Forest Entomology (2000) 2, 39±47 Rainfall and parasitic wasp (Hymenoptera: Ichneumonoidea) activity in successional forest stages at Barro Colorado Nature Monument, Panama, and La Selva Biological Station, Costa Rica B. A. Shapiro1 and J. Pickering Institute of Ecology, University of Georgia, Athens, GA 30602-2602, U.S.A. Abstract 1 In 1997, we ran two Malaise insect traps in each of four stands of wet forest in Costa Rica (two old-growth and two 20-year-old stands) and four stands of moist forest in Panama (old-growth, 20, 40 and 120-year-old stands). 2 Wet forest traps caught 2.32 times as many ichneumonoids as moist forest traps. The average catch per old-growth trap was 1.89 times greater than the average catch per second-growth trap. 3 Parasitoids of lepidopteran larvae were caught in higher proportions in the wet forest, while pupal parasitoids were relatively more active in the moist forest. 4 We hypothesize that moisture availability is of key importance in determining parasitoid activity, community composition and trophic interactions.

Insects Parasitoids: Natural Enemies of Helicoverpa
Queensland the Smart State insects Parasitoids: Natural enemies of helicoverpa Introduction Helicoverpa caterpillars (often called heliothis) are serious pests of many crops in Australia. A range of parasitoid and predatory insects attack helicoverpa. Identifying and conserving these beneficial insects is fundamental to implementing pest management with a reduced reliance on chemical insecticides. This brochure describes the most important parasitoids of helicoverpa in Australian broadacre crops. Parasitoids versus parasites: What’s the difference? Parasitoids kill their hosts; parasites (such Figure 1. Netelia producta is one of the as lice and fleas) do not.

Hymenoptera (Stinging Wasps)
Return to insect order home Page 1 of 3 Visit us on the Web: www.gardeninghelp.org Insect Order ID: Hymenoptera (Stinging Wasps) Life Cycle–Complete metamorphosis: Queens or solitary adults lay eggs. Larvae eat, grow and molt. This stage is repeated a varying number of times, depending on species, until hormonal changes cause the larvae to pupate. Inside a cell (in nests) or a pupal case (solitary), they change in form and color and develop wings. The adults look completely different from the larvae. Solitary wasps: Social wasps: Adults–Stinging wasps have hard bodies and most have membranous wings (some are wingless). The forewing is larger than the hindwing and the two are hooked together as are all Hymenoptera, hence the name "married wings," but this is difficult to see. Some species fold their wings lengthwise, making their wings look long and narrow. The head is oblong and clearly separated from the thorax, and the eyes are compound eyes, but not multifaceted. All have a cinched-in waist (wasp waist). Eggs are laid from the base of the ovipositor, while the ovipositor itself, in most species, has evolved into a stinger. Thus only females have stingers.

Oblong head Compound eyes Folded wings but not multifaceted appear Cinched in waist long & narrow Return to insect order home Page 2 of 3 Eggs–Colonies of social wasps have at least one queen that lays both fertilized and unfertilized eggs. Most are fertilized and all fertilized eggs are female. Most of these become workers; a few become queens.

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.

Biological Control of Insect Pests in Wheat
E-310 BIOLOGICAL CONTROL OF INSECT PESTS IN WHEAT Allen Knutson, Extension entomologist; Emory P. Boring, III Extension entomologist; G. J. Michels Jr. Associate professor of Entomology, Texas AgriLife Extension Service; and Frank Gilstrap Professor, Department of Entomology, Texas A&M University. All insects have natural enemies which, in addition to weather and food supply, limit their populations. This process, unaided and often unrecognized by man, is termed natural control. It is important to recognize the impact of natural control factors and, where possible, encourage their action. Biological control is the use of natural enemies to control insect pests. The ancient Chinese distributed nests of predatory ants among citrus trees to control caterpillars and borers. Today, biological control is an increasingly important component of integrated pest management (IPM) programs for agriculture as well as for urban environments. Biological control does not present the human health and environmental concerns associated with chemical pesticide use. Nor is there much chance pests will develop resistance to natural enemies, as commonly occurs with insecticides. However, there should be different expectations for biological control than for chemical control. Natural enemies are living organisms with specific environmental requirements and behaviors. While insecticides often produce rapid, uniform control of insect pests, weeks, months or even years may be required before natural enemies effectively control pests. As biological control takes effect and pests become scarce, their natural enemies may leave the area. Adverse weather conditions or changes in crop production practices also can reduce populations of natural enemies. In both cases, pest outbreaks may recur. Using biological control effectively requires a good understanding of the biology of the pest and its natural enemies, as well as the ability to identify their life stages in the field.

Identification Key to the Subfamilies of Ichneumonidae (Hymenoptera)
Identification key to the subfamilies of Ichneumonidae (Hymenoptera) Gavin Broad Dept. of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Notes on the key, February 2011 This key to ichneumonid subfamilies should be regarded as a test version and feedback will be much appreciated (emails to [email protected]). Many of the illustrations are provisional and more characters need to be illustrated, which is a work in progress. Many of the scanning electron micrographs were taken by Sondra Ward for Ian Gauld’s series of volumes on the Ichneumonidae of Costa Rica. Many of the line drawings are by Mike Fitton. I am grateful to Pelle Magnusson for the photographs of Brachycyrtus ornatus and for his suggestion as to where to include this subfamily in the key. Other illustrations are my own work. Morphological terminology mostly follows Fitton et al. (1988). A comprehensively illustrated list of morphological terms employed here is in development. In lateral views, the anterior (head) end of the wasp is to the left and in dorsal or ventral images, the anterior (head) end is uppermost. There are a few exceptions (indicated in figure legends) and these will rectified soon. Identifying ichneumonids Identifying ichneumonids can be a daunting process, with about 2,400 species in Britain and Ireland. These are currently classified into 32 subfamilies (there are a few more extralimitally). Rather few of these subfamilies are reconisable on the basis of simple morphological character states, rather, they tend to be reconisable on combinations of characters that occur convergently and in different permutations across various groups of ichneumonids.

Controlling Wasps, Bees and Hornets Around Your Home  Dr
Bringing information and education into the communities of the Granite State Controlling Wasps, Bees and Hornets Around Your Home Dr. Alan T. Eaton, Extension Specialist, Entomology Wasp encounters can be painful, even life-threatening, for a few highly sensitive people. Yet some New Hampshire species are not very aggressive and they also serve as valuable predators of soft-bodied insects. A hands-off policy might be better for some situations, while others might require careful, direct action. The choice you make should depend on the species and situation. Aggressive species New Hampshire is “blessed” with at least nine species of yellow- jackets, along with two other aggressive wasp species, the bald- faced hornet and giant European hornet. All these members of the wasp family Vespidae live in colonies and have similar life cycles. We also have a moderately aggressive, large solitary wasp, called the cicada killer. Most yellow jackets are about ½ inch long, with yellow and black banded bodies, and clear wings. Bald-faced hornets grow up to ¾ Yellow jacket wasp.

Only the mated females of Vespidae species survive the winter. These females overwinter individually, usually in deep leaf litter in the woods. In the spring, those that survived emerge and search for a site to start a tiny nest. Bald faced hornets prefer eaves of buildings, horizontal branches, or some similar site protected from rain.

Wasp and Bee Control
Wasp and bee control Jeff Hahn, University of Minnesota Extension Phil Pellitteri, University of Wisconsin Extension Donald Lewis, Iowa State University Extension Revised 2009 Wasps and bees are beneficial insects, although they are generally considered to be pests because of their ability to sting. Wasps, in particular, Fig. 1: Yellowjacket can become a problem in autumn when they may disrupt many outdoor activities. People often mistakenly call all stinging insects “bees.” While both social wasps and bees live in colonies ruled by queens and maintained by workers, they look and behave differently. It is important to distinguish between these insects because different methods may be necessary to control them if they become a nuisance. Appearance Fig. 2: Baldfaced hornet Wasps have a slender body with a narrow waist, slender, cylindrical legs, and appear smoothed-skinned and shiny. Yellowjackets, baldfaced hornets, and paper wasps are the most common types of wasps encountered by people (figs. 1, 2, 3). Bees are robust-bodied and very hairy compared with wasps (figs. 4, 5). Their hind legs are flattened for collecting and transporting pollen. Bees are important pollinators. Honey bees are responsible for more than 80% of the pollination required by most fruits, legumes, and vegetable seed plants as Fig. 3: Paper wasp well as many ornamentals that are grown in our landscapes. Bumble bees are important pollinators of native prairie plants. Food preferences Wasps are predators, feeding insects and other arthropods to their young, which develop in the nest. They are beneficial because they prey on many insects, including caterpillars, flies, crickets, and other pests.

The Differences Between Honey Bees and European Wasps
The differences between Honey Bees and European Wasps As you sit back in the garden, watching bees buzzing around pollinating flowers, try to relax: these flying insects have little interest in stinging you - unless you threaten them or are too close to the hive or nest. When observing bees, the first thing to do is look around to make sure you are not too close to a nest or hive (this includes ants nests and other flying insects hives – all insects are protective of their homes). If a flying insect does come close to you, then simply be still or move carefully away – don’t yell, scream, run or flap your arms about. Another good tip is to identify the differences between wasps and bees. Most Australian wasp species don’t look like bees as they have a small toothpick waist and fly with their legs hanging down. However, the European Wasp and Honey Bee can look quite similar. The colour of the European Wasp’s abdomen or “tail” is always clearly striped in strong yellow and black. They have yellow legs and their abdomen is a little longer than Honey Bees. European Wasps will fly in a zig-zag way when looking closely at food and then move ni a more direct way when travelling from place to place. European Wasps have bigger antennae and can wiggle them in a jerky way and also flick their wings. European Wasps are scavengers and will hang around your food, your pet’s food, rotting fruit or an open compost bin. This means you are more likely to have a problem with wasps hanging around.
