Rice-Feeding Insects and Selected Natural Enemies in West Africa Biology, ecology, identification E.A. Heinrichs and Alberto T. Barrion Illustrated by Cris dela Cruz and Jessamyn R. Adorada Edited by G.P. Hettel 2004 i The International Rice Research Institute (IRRI) and the Africa Rice Center (WARDA, the acronym for West Africa Rice Development Association) are two of fifteen Future Harvest research centers funded by the Consultative Group on International Agricultural Research (CGIAR). The CGIAR is cosponsored by the Food and Agriculture Organization of the United Nations (FAO), the International Bank for Reconstruction and Development (World Bank), the United Nations Development Programme, and the United Nations Environment Programme. Its membership comprises donor countries, international and regional organizations, and private foundations. IRRI, the world’s leading international rice research and training center, was established in 1960. Located in Los Baños, Laguna, Philippines, with offices in 11 other Asian countries, IRRI focuses on improving the well-being of present and future generations of rice farmers and consumers in developing countries, particularly those with low incomes. It is dedicated to helping farmers produce more food on limited land using less water, less labor, and fewer chemical inputs, without harming the environment. WARDA, established in 1971, with headquarters in Côte d’Ivoire and three regional research stations, is an autonomous intergovernment research association of African member states. Its mission is to contribute to food security and poverty alleviation in sub-Saharan Africa (SSA), through research, partnerships, capacity strengthening, and policy support on rice-based systems, and in ways that promote sustainable agricultural developement based on environmentally sound management of natural resources. WARDA hosts the African Rice Initiative (ARI), the Regional Rice Research and Development Network for West and Central Africa (ROCARIZ), and the Inland Valley Consortium (IVC).

  • Spider Bites
    Infectious Disease Epidemiology Section Office of Public Health, Louisiana Dept of Health & Hospitals 800-256-2748 (24 hr number) www.infectiousdisease.dhh.louisiana.gov SPIDER BITES Revised 6/13/2007 Epidemiology There are over 3,000 species of spiders native to the United States. Due to fragility or inadequate length of fangs, only a limited number of species are capable of inflicting noticeable wounds on human beings, although several small species of spiders are able to bite humans, but with little or no demonstrable effect. The final determination of etiology of 80% of suspected spider bites in the U.S. is, in fact, an alternate diagnosis. Therefore the perceived risk of spider bites far exceeds actual risk. Tick bites, chemical burns, lesions from poison ivy or oak, cutaneous anthrax, diabetic ulcer, erythema migrans from Lyme disease, erythema from Rocky Mountain Spotted Fever, sporotrichosis, Staphylococcus infections, Stephens Johnson syndrome, syphilitic chancre, thromboembolic effects of Leishmaniasis, toxic epidermal necrolyis, shingles, early chicken pox lesions, bites from other arthropods and idiopathic dermal necrosis have all been misdiagnosed as spider bites. Almost all bites from spiders are inflicted by the spider in self defense, when a human inadvertently upsets or invades the spider’s space. Of spiders in the United States capable of biting, only a few are considered dangerous to human beings. Bites from the following species of spiders can result in serious sequelae: Louisiana Office of Public Health – Infectious Disease Epidemiology Section Page 1 of 14 The Brown Recluse: Loxosceles reclusa Photo Courtesy of the Texas Department of State Health Services The most common species associated with medically important spider bites: • Physical characteristics o Length: Approximately 1 inch o Appearance: A violin shaped mark can be visualized on the dorsum (top).

  • STUDIES on the DERMAPTERA of the PHILIPPINES1 by G
    Pacific Insects 17(1): 99-138 1 October 1976 STUDIES ON THE DERMAPTERA OF THE PHILIPPINES1 By G. K. Srivastava2 Abstract: This paper includes the description of 18 new species belonging to the genera Diplatys, Epilandex, Chaetospania, Auchenomus, Apachyus, Allostethus, Proreus, Adiathella, Kosmetor and Timomenus. Besides these, 2 species are reported for the first time from the Philippine Islands. Our knowledge of the fauna of the Philippine Islands is largely based on the works of Caudell (1904), BoreUi (1915a, b, 1916, 1917, 1918,1921,1923,1926), Brindle (1966,1967) and Ramamurthi (1967). Recently, Srivastava (in press) has studied a collection of earwigs belonging to the Field Museum of Natural History, Chicago, which has resulted in the description of 14 new species. The present paper contains an account of some Dermaptera recently received for study from the Bishop Museum, Honolulu, Hawaii. The collection comprises 55 species (excluding 22 represented by either females or nymphs, identified up to generic level only) belonging to 28 genera, of which 18 species are new to science and 2 others are reported for the first time from the Philippines. The genus Apachyus Serville, hitherto unknown from the Philippine Islands, is represented by a new species. For some species that are represented by a large series in the collection it has been possible to study in detail the range of variations. A few females and nymphs could not be identified because the taxonomy of the whole order is based mainly on males, which often makes identification difficult. The fauna of the Philippine Islands appears to be not only rich in the number of species but also in the multiplicity of individuals for some species.

  • The Occurrence of Stalk-Eyed Flies (Diptera, Diopsidae) in the Arabian Peninsula, with a Review of Cluster Formation in the Diopsidae Hans R
    Tijdschrift voor Entomologie 160 (2017) 75–88 The occurrence of stalk-eyed flies (Diptera, Diopsidae) in the Arabian Peninsula, with a review of cluster formation in the Diopsidae Hans R. Feijen*, Ralph Martin & Cobi Feijen Catalogue and distribution data are presented for the six Diopsidae species known to occur in the Arabian Peninsula: Sphyracephala beccarii, Chaetodiopsis meigenii, Diasemopsis aethiopica, Diopsis arabica, Diopsis mayae and Diopsis sp. (ichneumonea species group). The biogeographical aspects of their distribution are discussed. Records of Diopsis apicalis and Diopsis collaris are removed from the list for Arabia as these were based on misidentifications. Synonymies involving Diasemopsis aethiopica and Diasemopsis varians are discussed. Only one out of four specimens in the D. elegantula type series proved conspecific with D. aethiopica. The synonymy of D. aethiopica and D. varians is rejected. A lectotype for Diasemopsis elegantula is now designated. D. elegantula is proposed as junior synonym of D. varians. A fly cluster of more than 80,000 Sphyracephala beccarii, observed in Oman, is described. The occurrence of cluster formations in the Diopsidae is reviewed, while a possible explanation is indicated.

  • Development of the Cursorial Spider, Cheiracanthium Inclusum (Araneae: Miturgidae), on Eggs of Helicoverpa Zea (Lepidoptera: Noctuidae)1
    Development of the Cursorial Spider, Cheiracanthium inclusum (Araneae: Miturgidae), on Eggs of Helicoverpa zea (Lepidoptera: Noctuidae)1 R. S. Pfannenstiel2 Beneficial Insects Research Unit, USDA-ARS, Weslaco, Texas 78596 USA J. Entomol. Sci. 43(4): 418422 (October 2008) Abstract Development of the cursorial spider, Cheiracanthium inclusum (Hentz) (Araneae: Miturgidae), from emergence to maturity on a diet of eggs of the lepidopteran pest Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) was characterized. Cheiracanthium inclusum developed to adulthood with no mortality while feeding on a diet solely of H. zea eggs and water. The number of instars to adulthood varied from 4-5 for males and from 4-6 for females, although most males (84.6%) and females (66.7%) required 5 instars. Males and females took a similar time to become adults (54.2 ± 4.0 and 53.9 ± 2.0 days, respectively). Egg consumption was similar between males and females for the first 4 instars, but differed for the 51 instar and for the total number of eggs consumed to reach adulthood (651.0 ± 40.3 and 866.5 ± 51.4 eggs for males and females, respectively). Individual consumption rates suggest the potential for high impact of C. inclusum individuals on pest populations. Development was faster and survival greater than in previous studies of C. inc/usum development. Key Words spider development, egg predation Spiders have been observed feeding on lepidopteran eggs in several crops (re- viewed by Nyffeler et al. 1990), but only recently has the frequency of these obser- vations (Pfannenstiel and Yeargan 2002, Pfartnenstiel 2005, 2008) suggested that lepidopteran eggs may be a common prey item for some families of cursorial spiders.

Spies Laboratory for Ecological Chemistry, Department of Chemistry, University of Stellenbosch, Stellenbosch 7600, South Africa Z. Naturforsch. 46c, 678-686 (1991); received January 8, 1991 Cyclic Acetals, Darmstoff, Eldana saccharina, Mass Spectrometry, NMR Four constituents of the hair pencil secretion of the male African sugarcane stalk borer, Eldana saccharina, having a molecular mass of 312 and peculiar El mass spectra with an excep­ tionally abundant base peak at m/z 103, were isolated preparatively from an extract of the se­ cretion. Using 'H and l3C NMR spectral analysis, these constituents were identified as five- and six-membered cyclic glycerol acetals of Z-9-hexadecenal, viz. cis- and trans-2-(Z- 8-pentadecenyl)-4-hydroxymethyl-l,3-dioxolane, and cis- and fra«s-2-(Z-8-pentadecenyl)- 5-hydroxy-l,3-dioxane. These compounds are related to the 2-alkenyl-4-hydroxymethyl-l,3- dioxolane dihydrogen phosphate esters, known to be the active constituents of the smooth muscle contracting acidic phospholipid (Darmstoff) which was isolated from the intestine of mammals. The presence of these acetals in the tail brush secretion of E. saccharina could possi­ bly be the first evidence that compounds related to the active principle of Darmstoff, may also be present in the insect kingdom. The possibility that these four compounds or their dihydro­ gen phosphate esters might play a part in the eversion or retraction of the tail brushes of the male insect, is briefly discussed.

JAVIER SALGUEIRO- SEPÚLVEDA1 1Laboratorio de Aracnología, Facultad de Ciencias, Departamento de Biología Comparada, Universidad Nacional Autónoma de México, Circuito Exterior s/n, Colonia Copilco el Bajo. C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views.

Koch, 1872) n. comb., Robertia braueri (Simon, 1898). n. comb., Selimus placens (Blackwall, 1877) n. comb., Sesato setosa n. gen, n. sp., Spinembolia clabnum (Roberts, 1978) n. comb., and Stoda libudum (Roberts, 1978) n. comb.. Also the opposite sex of four species are described for the fi rst time, namely females of Phycosoma spundana (Roberts, 1978) and P. menustya (Roberts, 1983) and males of Spinembolia clabnum (Roberts, 1978) and Stoda libudum (Roberts, 1978). Finally the morphology and terminology of the male and female secondary genital organs are discussed. Key words. - copulatory organs, morphology, Seychelles, spiders, Theridiidae. INTRODUCTION Theridiids or comb-footed spiders are very variable in general apperance often with considerable sexual dimorphism.

The host recognition and acceptance behaviour of two braconid larval parasitoids (Cotesia sesamiae and C. flavipes) were studied using natural stemborer hosts (i.e., the noctuid Busseola fusca for C. sesamiae, and the crambid Chilo partellus for C. flavi- pes) and a non-host (the pyralid Eldana saccharina). A single larva was introduced into an arena together with a female parasitoid and the behaviour of the wasp recorded until it either stung the larva or for a maximum of 5 min if it did not sting the larva. There was a clear hierarchy of behavioural steps, which was similar for both parasitoid species. In the presence of suitable host larvae, after a latency period of 16–17 s, the wasp walked rapidly drumming the surface with its antennae until it located the larva.
