  • Orius Insidiosus (Say) and ENTOMOPATHOGENS AS POSSIBLE BIOLOGICAL CONTROL AGENTS for THRIPS
    Orius insidiosus (Say) AND ENTOMOPATHOGENS AS POSSIBLE BIOLOGICAL CONTROL AGENTS FOR THRIPS Ronald D. Oetting and Ramona J. Beshear Department of Entomology University of Georgia College of Agriculture, Experiment Stations Georgia Station Griffin, Georgia USA The entomology program in ornamental floriculture at the University of Georgia places primary emphasis on commercial production of flowering and foliage plants under greenhouse conditions. Thrips management is a major part of that program. Several species of foliage and flower inhabiting species are pests on greenhouse crops. The western flower thrips, Frankliniella occidentalis (Pergande), has become the most important pest of the thrips complex during this decade. Other thrips species have also become more difficult to control or occur more frequently on greenhouse crops in different areas of the country. The subject of this paper is the potential use of natural enemies for the management of thrips under greenhouse and other environments. The use of predatory mites for thrips management is discussed in the previous paper and we will focus on two other potential natural enemies: entomopathogens and a hemipteran predator in the genus Orius. Neither of these natural enemies have been utilized in commercial programs for thrips control in greenhouses in the United States but both occur as natural enemies limiting populations of thrips in their respective environments. They should both be considered as potential tools for thrips management. Entomopathogens Entomopathogens are organisms utilized for management of insect populations and the fungi are the only group of pathogens which have been studied for thrips control. There have been three genera of fungi reported from thrips: Verticillium, Entomophthora, and Paecilomyces.

State Street, West Lafayette, Indiana 47907-2089, USA, ‡USDA-ARS, Invasive Insect Biocontrol and Behavior Laboratory, BARC-West, Beltsville, Maryland 20705, USA Abstract The soybean aphid, Aphis glycines (Hemiptera: Aphididae), is a pest of soybeans in Asia, and in recent years has caused extensive damage to soybeans in North America. Within these agroecosystems, generalist predators form an important component of the assemblage of natural enemies, and can exert significant pressure on prey populations. These food webs are complex and molecular gut-content analyses offer nondisruptive approaches for exam- ining trophic linkages in the field. We describe the development of a molecular detection system to examine the feeding behaviour of Orius insidiosus (Hemiptera: Anthocoridae) upon soybean aphids, an alternative prey item, Neohydatothrips variabilis (Thysanoptera: Thripidae), and an intraguild prey species, Harmonia axyridis (Coleoptera: Coccinellidae). Specific primer pairs were designed to target prey and were used to examine key trophic connections within this soybean food web. In total, 32% of O. insidiosus were found to have preyed upon A. glycines, but disproportionately high consumption occurred early in the season, when aphid densities were low.

  • Vegetable Pests: European Corn Borer W
    W 393 Frank A. Hale, Professor Gary Phillips, Graduate Research Assistant Rob Pivar, Graduate Research Assistant Jerome F. Grant, Professor Department of Entomology and Plant Pathology The European corn borer, Ostrinia nubilalis (Order Lepidoptera: Family Crambidae, previously Pyralidae), is a common agricultural pest found abundantly in the American Midwest Corn Belt as well as the South and Mid-South. It is a severe pest of corn, Zea mays, and may infect other crops that include potatoes, peppers, lima and snap beans, cotton, oats, hops, soybeans, and tomatoes. Ornamental flowering plants, such as gladiolus and asters, are also affected by this pest. In fact, this invasive insect infests more than 200 plant species in the United States. Damage inflicted by European corn borers costs American farmers and horticulturalists upwards of $1 billion annually. The European corn borer is an introduced North American pest that probably originated in Hungary or Italy and arrived in the United States in shipments of broom corn, which was used to manufacture brooms in the early 20th century. It was first discovered in the vicinity of Boston, Massachusetts. During the next 20 years, it spread from the Atlantic seaboard to Wisconsin, and soon after, moths were found throughout the eastern United States and southern Canada as far south as the Gulf states and west to the Rocky Mountains. After World War II, it became more established in the southern United States, including Tennessee. Currently, the European corn borer is found in all the major corn-producing states of the Plains, Midwest and South. Damage The European corn borer larva (Figure 1), which feeds on all succulent, above-ground tissues of corn plants, especially the ear, is the destructive stage of this insect.

North St., Geneva, NY 14456 ([email protected]; [email protected]; [email protected]), 1Corresponding author, e-mail: [email protected] Received 31 March 2016; Accepted 7 May 2016 Abstract Downloaded from The corn earworm, Helicoverpa zea (Boddie), is a polyphagous pest found throughout the United States, where it attacks many field and vegetable crops. Although H. zea has long been a traditional pest of sweet corn, its im- portance to this crop has increased dramatically over the past two decades. In this review, we summarize infor- mation critical for current and future management of H. zea in sweet corn production in the United States. First, we discuss the pest status of H. zea and its life history, including migration, infestation and larval development, http://jee.oxfordjournals.org/ diapause, overwintering, and abiotic factors that affect its biology. Next we describe monitoring methods, crop protection decision-making processes, chemical control options, and the use of genetic technologies for control of H. zea. Alternative H. zea management options including biological control, cultural controls, host plant resis- tance, and pheromone disruption are also reviewed. The role of climate change and its effects on H. zea and its ecology are discussed, as well as the recent invasion of its relative, Helicoverpa armigera (Hu¨bner), which is a major pest of corn in other parts of the world.

  • Two-Spotted Spider Mite Plant Pest Fact Sheet
    TWO-SPOTTED SPIDER MITE Minnesota Department of Agriculture * Biological Control Program Fact Sheet Description Life Cycle Barely visible to the unaided eye, mature two-spotted spi- Spider mites are known for their ability to reproduce quickly. der mites bear the characteristic black spots that are their Adult two-spotted spider mite females can lay hundreds of namesake. Adults are straw yellow; nymphs are merely eggs in a lifetime. Eggs hatch in 2-4 days; nymphs develop in smaller versions of adults and range from pale yellow to 2-4 days. Adults can live up to 21 days and respond well to pale yellow-green. Two-spotted spider mites reproduce hot, dry environments. extremely fast and can overwhelm plants by sheer num- bers. Leaves of plants infested with spider mites show a distinct spotted effect called stippling. Spider mites cause stippling because they feed on plant cells one at a time. Like their name suggests, spider mites can spin webbing; heavily infested plants are typically covered with the fine webbing they use to disperse from old plants to fresh ones. Two-spotted spider mite egg Damage Spider mites feed on plants one cell at a time. Small numbers of spider mites cause leaf stippling. Left unchecked, spider mite infestations build up quickly in warm temperatures and can destroy plants when infestations are not detected Two-spotted spider mite Two-spotted spider mites on early enough. Thin-leafed plants are more susceptible to adult fingertip spider mites than plants with thick or waxy leaves. Identification Adult two-spotted spider mites (Tetranychus urticae) are straw yellow colored and can be identified by their charac- teristic two black spots.
