Fungal entomopathogens provide an attractive alternative to synthetic insecticides for weevil control because they pose a lesser risk to human health and the environment. This review summarises the available data on the performance of these entomopathogens when used against weevils in horticultural crops. We integrate these data with information on weevil biology, grouping species based on how their developmental stages utilise habitats in or on their hostplants, or in the soil.

G. McClurq USDA, AgricuLtural Research Seruice, North Central Regional Plant Introduction Station, Ioua State UniDersitA, Ames, IA 5OO11 Receiued: Nouernber 25, 1996 Accepted: Nouember 17. 1997 SUMMARY The sunflower moth, I{omoeosoma electellum (Hulst), is a major pest of sunflower (Helianthus annuus L.) mainly in the central and southern United States. The sunflower moth is most commonly controlled w"ith pesticides. Resistânt plants would provide an environmentally friendly approach to con- trolling this pest. Evaluation of 680 cultivated sunflower accessions in the U.S. National Plant Germplasm System's sunflower (Flelianthus spp.) collection at the North Central Regional Plant Introduction Stauon, Ames, IA, USA. revealed 51 accessions resistant to sunflower moth feeding. A 1-3-5-7-9 rating scale is presented to compare accessions damaged by the pest. The proceeding evalua- tion data were entered into the Germplasm Resources Information Network (GRIN) and made available to researchers worldwide. Key words: Sunflower, Helio,nthus, Homoeosoma electellum, plarfi germplasm, host plant resistance to insects, sunflower moth. INTRODUCTION The United States National Plant Germplasm System's collection of sunflower, Helianthus spp., contains 3,670 accessions of which 1,495 are cultivated (H. clnnllus L.). From l9B5 to 1992, 680 cultivated accessions were evaluated for sun- flower moth, Homoeosoma electellum (Hulst)(Lepidoptera: Pgraltdae), resistance. The procedure used for these evaluations involved placing eggs on sunflower heads and covering with a Delnet@ bag until harvest.

    Dumfries & Galloway Wildlife Review Cover Image: Hedgehog by Keith Kirk. Keith is a former Dumfries & Galloway Council ranger and now helps to run Nocturnal Wildlife Tours based in Castle Douglas. The tours use a specially prepared night tours vehicle, complete with external mounted thermal camera and internal viewing screens. Each participant also has their own state- of-the-art thermal imaging device to use for the duration of the tour. This allows participants to detect animals as small as rabbits at up to 300 metres away or get close enough to see Badgers and Roe Deer going about their nightly routine without them knowing you’re there.

  • REVISION of the FAMILY CHLOROPIDAE (DIPTERA) in IRAQ Hanaa H. Al-Saffar Iraq Natural History Research Center and Museum, Univers
    Hanaa H. Al-Saffar Bull. Iraq nat. Hist. Mus. http://dx.doi.org/10.26842/binhm.7.2018.15.2.0113 December, (2018) 15 (2): 113-121 REVISION OF THE FAMILY CHLOROPIDAE (DIPTERA) IN IRAQ Hanaa H. Al-Saffar Iraq Natural History Research Center and Museum, University of Baghdad, Baghdad, Iraq Corresponding author: [email protected] Received Date:27 March 2018 Accepted Date:30 April 2018 ABSTRACT The aim of this study is to survey and make to revision the genera and species of Chloropidae fauna of Iraq. The investigation showed four species belonging four genera, which belongs to two subfamilies, and one unidentified species belonging to the genus Elachiptera Maquart, The specimens were compared with stored insects at Department of Entomology and invertebrates, Iraq Natural History Research Center and Museum. Key words: Brachycera, Chloropidae, Diptera, Eye fly, Grass fly, Iraq. INTRODUCTION The family Chloropidae Schoenher,1840 (frit flies, grass flies or eye flies) belongs to super family Carnoidea. It has four subfamilies: Chloropinae, Oscinellinae, Rhodesiellinae, and Siphonellpsinae (Brues et al.,1954). The members of Chloropidae are worldwide distribution or cosmopolitan and are found in all Zoogeographical regions except Antarctica; they are about 3000 described species under 200 genera (Sabrosky,1989; Canzoneri, et al., 1995; Nartshuk, 2012; Bazyar et al., 2015). The grass flies are also found in marshes, vegetation areas, forests; the members of the family are phytophagous. Some species as a gall maker of stems likes Lipara lucens Meigen, 1830 on Phragmites australis (Poaceae) are affected on the morphological tissue (Van de Vyvere and De Bruyn, 1988); and many larvae feed and developed flower heads, shoots and seeds of Poaceae and some feed on the stems of cereals, thus affected of economic production (Alford,1999; Karpa, 2001;Petrova et al., 2013).

  • 197 Section 9 Sunflower (Helianthus
    SECTION 9 SUNFLOWER (HELIANTHUS ANNUUS L.) 1. Taxonomy of the Genus Helianthus, Natural Habitat and Origins of the Cultivated Sunflower A. Taxonomy of the genus Helianthus The sunflower belongs to the genus Helianthus in the Composite family (Asterales order), which includes species with very diverse morphologies (herbs, shrubs, lianas, etc.). The genus Helianthus belongs to the Heliantheae tribe. This includes approximately 50 species originating in North and Central America. The basis for the botanical classification of the genus Helianthus was proposed by Heiser et al. (1969) and refined subsequently using new phenological, cladistic and biosystematic methods, (Robinson, 1979; Anashchenko, 1974, 1979; Schilling and Heiser, 1981) or molecular markers (Sossey-Alaoui et al., 1998). This approach splits Helianthus into four sections: Helianthus, Agrestes, Ciliares and Atrorubens. This classification is set out in Table 1.18. Section Helianthus This section comprises 12 species, including H. annuus, the cultivated sunflower. These species, which are diploid (2n = 34), are interfertile and annual in almost all cases. For the majority, the natural distribution is central and western North America. They are generally well adapted to dry or even arid areas and sandy soils. The widespread H. annuus L. species includes (Heiser et al., 1969) plants cultivated for seed or fodder referred to as H. annuus var. macrocarpus (D.C), or cultivated for ornament (H. annuus subsp. annuus), and uncultivated wild and weedy plants (H. annuus subsp. lenticularis, H. annuus subsp. Texanus, etc.). Leaves of these species are usually alternate, ovoid and with a long petiole. Flower heads, or capitula, consist of tubular and ligulate florets, which may be deep purple, red or yellow.

The list includes records before 1992, which have been published in previous papers, as well as data from an almost ten-year survey using Rothamsted suction traps and Moericke traps. The recorded aphidofauna consisted of 301 species. The family Aphididae is represented by 13 subfamilies and 120 genera (300 species), while only one genus (1 species) belongs to Phylloxeridae. The aphid fauna is dominated by the subfamily Aphidi- nae (57.1 and 68.4 % of the total number of genera and species, respectively), especially the tribe Macrosiphini, and to a lesser extent the subfamily Eriosomatinae (12.6 and 8.3 % of the total number of genera and species, respectively).
