M. Steidle * Institute of Zoology/Animal Ecology 220c, Hohenheim University, Garbenstr. 30, Stuttgart 70599, Germany; steffi[email protected] (S.N.); [email protected] (M.P.) * Correspondence: [email protected]; Tel.: +49-711-23667 Academic Editors: Christos Athanassiou, Nickolas Kavallieratos, Vincenzo Palmeri and Orlando Campolo Received: 28 June 2016; Accepted: 27 July 2016; Published: 1 August 2016 Abstract: Legal requirements and consumer demands for residue-free products pose a big challenge for pest control in grain stores. One possible alternative to chemical insecticides is biological pest control with the pteromalid wasp Lariophagus distinguendus against the weevils Sitophilus granarius, S. oryzae (Coleoptera: Dryophtoridae), and many other storage pest beetles. The use of this wasp as a biocontrol agent was already suggested in 1919 by Prof. Dr. Hase [1]. Despite many studies on host-finding and behavioral biology, the applied aspect was neglected until 1994. Nowadays the wasps are commercially available and can now even be reared on-site, facilitating their use tremendously. This review highlights the milestones in L. distinguendus research, gives insights in current studies, and ventures a glimpse into the future. Keywords: biological pest control; Pteromalidae; Lariophagus distinguendus; Sitophilus sp.; Stegobium paniceum; stored product protection 1. Introduction Stored grain is threatened by a vast number of storage pests, mostly insects [2]. Nowadays integrated pest management strategies (IPM) have superseded the excessive application of chemical insecticides used against storage pests in the past.

  • 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.

  • Contribution to Knowledge of the Tribe Gastrallini (Coleoptera: Bostrichoidea: Ptinidae) - IV
    Studies and Reports Taxonomical Series 6 (1-2): 271-275, 2010 Contribution to knowledge of the tribe Gastrallini (Coleoptera: Bostrichoidea: Ptinidae) - IV. Review of the genus Falsogastrallus, with description of new species Petr ZAHRADNÍK Forestry and Game Management Research Institute Strnady 136, CZ-156 04 Praha 5 - Zbraslav, Czech Republic e-mail: [email protected] Taxonomy, new species, Coleoptera, Ptinidae, Falsogastrallus Abstract. Falsogastrallus Pic, 1914 (= Gastrallomimum Pic, 1939; = Neogastrallus Fisher, 1938) is represented by 16 species, one of them being new to science - Falsogastrallus indicus sp. nov. These species are distributed throughout the world, except the Australian region. INTRODUCTION The fi rst (and the last) complex review of the genus Falsogastralus Pic, 1914 was presented by Español (1979). He indicated eight species (including F. barbieri Pic) and noticed other 3 species, from which F. pendleburyi Pic, 1936 is now placed in the genus Methemus Broun, 1882. He used incorrectly name F. fi brinocens (Fisher, 1938) for F. librinocens (Fisher, 1938). Español (1977, 1979) indicated one problematic species - F. barbieri Pic, but he wrote that this name is probably nomen nudum, because he did not fi nd its description, but only a designated specimen in the Pic’s collection (“Saigon, 6-ix-50, J. Barbier, Falsogastrallus barbieri sp.n.”). I have not fi nd any description of this species, too. This species was not published also in Zoological records. According to my opinion this species is valid and the author is Español (1979), because he made a short description and cited the locality, and he also drew aedeagus of this species, which is in compliance with ICZN rules.

This study shows how forest regrowth affects beetle species associated with old oaks in south-eastern Sweden. Beetles were trapped by pitfall traps placed in hollows and window traps placed near hollows in oak trunks in pasture woodlands. We assessed the influence of forest regrowth, tree size and original canopy cover on the species richness of saproxylic beetles (a total of 120 species identified) and the occurrence of 68 saproxylic beetle species in particular.

    I COLLEGE OF AGRICULTURE COOPERATIVE EXTENSION SERVICE WASHINGTON STATE UNIVERSITY PULLMAN, WASHINGTON 99163 May, 1966 E. 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.
