  • Bad Bugs: Warehouse Beetle
    Insects Limited, Inc. Pat Kelley, BCE Bad Bugs: Warehouse Beetle complaining customer. That is the nature of the Warehouse beetle. Let’s take a close look at this common stored product insect: The Warehouse beetle prefers feeding on animal protein. This could be anything from road kill to dog food to powdered cheese and milk. The beetle will feed on plant material but a dead insect or mouse would be its preferred food source. You will often find Warehouse beetles (Trogoderma spp.) feeding on dead insects. It is important to empty these lights on a regular basis. The larva (see figure) of the Warehouse beetle is approximately 1/4-inch-long Larval color varies from yellowish/white to dark brown as the larvae mature. Warehouse beetle larvae have two different tones of hairs on the posterior end. These guard hairs protect them against attack from the rear. The Warehouse beetle has about 1,706 hastisetae hairs If there is an insect that is truly a voracious feeder and about 2,196 spicisetae hairs according to a and a potential health hazard to humans and publication by George Okumura. Since a larva sheds young animals, the Warehouse beetle falls into that its hairs during each molt, the damage of this pest category because of the long list of foods that it insect comes from the 1000’s of these pointed hairs attacks. Next to the dreaded quarantine pest, that escape and enter a finished food product as an the Khapra beetle, it is the most serious stored insect fragment. These insect fragments then can be product insect pest with respect to health.

Mo 2631 ENEMIES OF THE ALFALFA LEAFCUTTING BEE AND THEIR (X)NTROL by Carl Johansen and Jack Eves Associate Entomologist and Experimental Aide Department of Entomology One of the major pollinators of alfalfa grown for seed in the state of Washington, the alfalfa leafcutting bee (Megachile rotundata), has been increasingly killed by insect parasites and nest destroyers during the past 3 years. Seventeen of these pests have been identified to date. The most numerous parasite is the small wasp, Monodontomerus obscurus . It is shiny blue-green and only 1/8 to 1/6 inch long. A carpet beetle, Trogoderma glabrum, is currently the most abundant nest destroyer. It is oval, dull black with three faint lines of white bristles across the wing covers, and 1/10 to 1/7 inch long. Control Control of the parasites and nest destroyers of the alfalfa leafcutting bee is largely a matter of good management practices. Since all parasite adults complete emergence at least t wo days before the ma le leafcutters begin to emerge, they can be readily destroyed in an incubation room. Pests such as Trogoderma remain active in the bee nests , feeding and reproducing through­ out the year. A more complex system of sanitary measures is required to keep them below damaging population levels. Helpful practices are classified as: (1) cleanup, (2) cold storage , ( 3) nest renovation, and (4) use of poison baits. Cleanup -- To trap the parasites emerging in your leafcutting bee incubation room, simply place a pan of water beneath a light bul b.

  • Diagnostic Protocols for Regulated Pests
    DIAGNOSTIC PROTOCOLS FOR REGULATED PESTS Trogoderma granarium Introduction The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae) is a stored product pest of great importance. Its importance lies not only in the capabilities of causing serious damage to stored dry commodities but also that countries having established populations are facing export restrictions. The Khapra beetle is thought to have originated from the Indian subcontinent but has become established in a number of Asian, Middle Eastern, African, and some European countries. It is one of the very few stored product pests that has limited worldwide distribution. T. granarium has very limited ability to spread without human aid as it is unable to fly. It is very important to distinguish between those records which relate to introductions and those of established infestations. The Khapra beetle is established within an area broadly limited north by central Asia, south by the Equator, west by the Sahel of West Africa and east by Myanmar; i.e. the warm dry regions along the Suez route from the Indian subcontinent to Europe. This area includes the southeastern part of the EPPO region. Khapra beetle has been introduced into areas of similar climatic conditions elsewhere particularly the alternative route between India and Europe around Africa. Currently its status in southern Africa is unclear and it may be absent there now. Initially introductions caused severe damage but outbreaks have been local and in most cases have been eradicated. In general, Khapra beetle is only successful in competition with other major stored product pests in conditions of low humidity. It has also established in some areas of unfavourable climate, where it survives only in protected and/or heated environments such as maltings and feedmills, for example in Europe, Korea and Japan.

  • Towards Classical Biological Control of Leek Moth
    ____________________________________________________________________________ Ateyyat This project seeks to provide greater coherence for the biocontrol knowledge system for regulators and researchers; create an open access information source for biocontrol re- search of agricultural pests in California, which will stimulate greater international knowl- edge sharing about agricultural pests in Mediterranean climates; and facilitate the exchange of information through a cyberinfrastructure among government regulators, and biocontrol entomologists and practitioners. It seeks broader impacts through: the uploading of previ- ously unavailable data being made openly accessible; the stimulation of greater interaction between the biological control regulation, research, and practitioner community in selected Mediterranean regions; the provision of more coherent and useful information to enhance regulatory decisions by public agency scientists; a partnership with the IOBC to facilitate international data sharing; and progress toward the ultimate goal of increasing the viability of biocontrol as a reduced risk pest control strategy.

  • Semiochemicals and Entomopathogenic Microbials
    Semiochemicals and Entomopathogenic Microbials Subjects: Entomology Submitted by: Anamika Sharma Definition Biological control agents and semiochemicals have become essential parts of the integrated pest management of insect pests over the last several years, as the incorporation of semiochemicals with natural enemies and entomopathogenic microbials has been gaining significance. Semiochemicals can enable the successful dispersal of entomopathogenic microbials. Using semiochemicals to disseminate microbial pathogens is still at the initial stage. For dispersal of entomopathogenic fungus semiochemicals have been successfully used in field conditions, however same can not be said about the other microbials such as specially for bacterial and viral entomopathogens. 1. Fungi Pathogens may be dispersed naturally by parasitoids, predators, and the feces of insects, birds, and mammals, and surface contamination [[1]]. However, for entomopathogenic fungi, natural dispersal, in additional to the aerial movement of spores, is also known to occur through the movement of the targeted insect pests and pollinators, as shown in honey bees in canola production, where honey bees disperse B. bassiana, increasing the mortality of Lygus sp. (Hahn) (Hemiptera: Miridae) [[2],[3]]. A selective and assisted dissemination technique called auto-dissemination is also extremely helpful in spreading entomopathogens [[1]]. Auto-dissemination can be used to target both adults and larvae of some insect pests [[4],[5],[6]]. Semiochemicals are being used to increase the

Ebadollahi, Tel: +989192436834, P.O.Box 467, E-mail: [email protected], [email protected] Received: 05. March 2011 / Accepted: 23. October 2011 / Available online: 30. October 2011 Abstract. Sun pest, Eurygaster integriceps Puton (Heteroptera: Scutelleridae), is the major pest of wheat and barley in all regions except the Northern and Southern shores of Iran. This pest causes high damage to all vegetative hosts (stems, spikes and leaves) by feeding sap in nymph and adult stages (mother and new generation). Information on its biology and population density was evaluated in order to gain a better understanding of the best way to its control. In this study, we studied the effects of Sardari (dry land) and Gaskogen (aqua culture) wheat cultivars and Sahand barely cultivar (dry land) on population density of nymphs and adults of this pest. Present study was done by sweeping with hand-net and counting square meter quadrate methods in Korayim region of Ardabil, Iran. Results showed that population density of nymphs and adults of E. integriceps on aqua culture cultivar of wheat (Gaskogen) were more than other wheat and barley cultivars.

Abstract : This study was conducted in wheat barley fields in Diyala governorate, Iraq during the growing season 2017 and 2018 to estimate the activity and the rate of parasitoids of eggs and adults of Eurygasterintegriceps in infested fields. Trissolcussemisteriatus (Hymenoptera: Scelionidea) were found an important egg parasitoid on egg of sunn pest in Iraq. The first parasitized eggs were observed after 10 days of laying mass eggs in fields with average 50% in two fields in Mugdadiayah and Baladroz regions. The rate of parasitism was reached high level in the end of March (80 and 62.4% respectively) and continuous to the end oviposition period in the first week of April. Phasia spp (Diptera: Tachinidae) was recorded as a new parasitoid on the adults of sunn pest in Iraq. The rate of parasitism were 20,13 and 40% in Mugdadiayah, and 17, 20 and 20 in Baladroz on 15, 25 March and fifth April respectively . Key words: Wheat, Barley, Infested fields, Parasitism. 1. Introduction especially imperator plants Cylindricalepisodic. The Sunn pest Eurygaster spp Put on (Hemiptera: largest economic losses were recorded in Adana variety Scutelleridae) is very damaging pest of wheat and (20%).
