[email protected]; 4Sustainable Perennial Crops Laboratory, U. S. Department of Agriculture, Agricultural Research Service, Building 001, Beltsville MD 20705, U.S.A. [email protected] ABSTRACT. The coffee berry borer, Hypothenemus hampei, is the most important pest of coffee worldwide, causing an estimated $500 million in damage annually. Infestation rates from 50-90% have been reported, significantly impacting coffee yields. Adult female H. hampei bore into the berry and lay eggs whose larvae hatch and spend their entire larval life within the berry, feeding on the coffee bean, lowering its quality and sometimes causing abscission. Biological control of H. hampei using parasitoids, fungi and nematodes has been reported but potential predators such as ants and predatory thrips, which have been observed in and around the coffee berries, have received little attention. This study reviews previous H. hampei biological control efforts and focuses on the role of predators in H. hampei biological control, an area in which tracking trophic associations by direct observation is not possible in part due to the cryptic nature of the biology of H.

  • Phylogenetic and Population Genetic Studies on Some Insect and Plant Associated Nematodes
    PHYLOGENETIC AND POPULATION GENETIC STUDIES ON SOME INSECT AND PLANT ASSOCIATED NEMATODES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Amr T. M. Saeb, M.S. * * * * * The Ohio State University 2006 Dissertation Committee: Professor Parwinder S. Grewal, Adviser Professor Sally A. Miller Professor Sophien Kamoun Professor Michael A. Ellis Approved by Adviser Plant Pathology Graduate Program Abstract: Throughout the evolutionary time, nine families of nematodes have been found to have close associations with insects. These nematodes either have a passive relationship with their insect hosts and use it as a vector to reach their primary hosts or they attack and invade their insect partners then kill, sterilize or alter their development. In this work I used the internal transcribed spacer 1 of ribosomal DNA (ITS1-rDNA) and the mitochondrial genes cytochrome oxidase subunit I (cox1) and NADH dehydrogenase subunit 4 (nd4) genes to investigate genetic diversity and phylogeny of six species of the entomopathogenic nematode Heterorhabditis. Generally, cox1 sequences showed higher levels of genetic variation, larger number of phylogenetically informative characters, more variable sites and more reliable parsimony trees compared to ITS1-rDNA and nd4. The ITS1-rDNA phylogenetic trees suggested the division of the unknown isolates into two major phylogenetic groups: the HP88 group and the Oswego group. All cox1 based phylogenetic trees agreed for the division of unknown isolates into three phylogenetic groups: KMD10 and GPS5 and the HP88 group containing the remaining 11 isolates. KMD10, GPS5 represent potentially new taxa. The cox1 analysis also suggested that HP88 is divided into two subgroups: the GPS11 group and the Oswego subgroup.

  • Leeches As the Intermediate Host for Strigeid Trematodes: Genetic
    Pyrka et al. Parasites Vectors (2021) 14:44 https://doi.org/10.1186/s13071-020-04538-9 Parasites & Vectors RESEARCH Open Access Leeches as the intermediate host for strigeid trematodes: genetic diversity and taxonomy of the genera Australapatemon Sudarikov, 1959 and Cotylurus Szidat, 1928 Ewa Pyrka1, Gerard Kanarek2* , Grzegorz Zaleśny3 and Joanna Hildebrand1 Abstract Background: Leeches (Hirudinida) play a signifcant role as intermediate hosts in the circulation of trematodes in the aquatic environment. However, species richness and the molecular diversity and phylogeny of larval stages of strigeid trematodes (tetracotyle) occurring in this group of aquatic invertebrates remain poorly understood. Here, we report our use of recently obtained sequences of several molecular markers to analyse some aspects of the ecology, taxon- omy and phylogeny of the genera Australapatemon and Cotylurus, which utilise leeches as intermediate hosts. Methods: From April 2017 to September 2018, 153 leeches were collected from several sampling stations in small rivers with slow-fowing waters and related drainage canals located in three regions of Poland. The distinctive forms of tetracotyle metacercariae collected from leeches supplemented with adult Strigeidae specimens sampled from a wide range of water birds were analysed using the 28S rDNA partial gene, the second internal transcribed spacer region (ITS2) region and the cytochrome c oxidase (COI) fragment. Results: Among investigated leeches, metacercariae of the tetracotyle type were detected in the parenchyma and musculature of 62 specimens (prevalence 40.5%) with a mean intensity reaching 19.9 individuals. The taxonomic generic afliation of metacercariae derived from the leeches revealed the occurrence of two strigeid genera: Aus- tralapatemon Sudarikov, 1959 and Cotylurus Szidat, 1928.

  • Evaluation of Some Vulval Appendages in Nematode Taxonomy
    Comp. Parasitol. 76(2), 2009, pp. 191–209 Evaluation of Some Vulval Appendages in Nematode Taxonomy 1,5 1 2 3 4 LYNN K. CARTA, ZAFAR A. HANDOO, ERIC P. HOBERG, ERIC F. ERBE, AND WILLIAM P. WERGIN 1 Nematology Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected], [email protected]) and 2 United States National Parasite Collection, and Animal Parasitic Diseases Laboratory, United States Department of Agriculture–Agricultural Research Service, Beltsville, Maryland 20705, U.S.A. (e-mail: [email protected]) ABSTRACT: A survey of the nature and phylogenetic distribution of nematode vulval appendages revealed 3 major classes based on composition, position, and orientation that included membranes, flaps, and epiptygmata. Minor classes included cuticular inflations, protruding vulvar appendages of extruded gonadal tissues, vulval ridges, and peri-vulval pits. Vulval membranes were found in Mermithida, Triplonchida, Chromadorida, Rhabditidae, Panagrolaimidae, Tylenchida, and Trichostrongylidae. Vulval flaps were found in Desmodoroidea, Mermithida, Oxyuroidea, Tylenchida, Rhabditida, and Trichostrongyloidea. Epiptygmata were present within Aphelenchida, Tylenchida, Rhabditida, including the diverged Steinernematidae, and Enoplida. Within the Rhabditida, vulval ridges occurred in Cervidellus, peri-vulval pits in Strongyloides, cuticular inflations in Trichostrongylidae, and vulval cuticular sacs in Myolaimus and Deleyia. Vulval membranes have been confused with persistent copulatory sacs deposited by males, and some putative appendages may be artifactual. Vulval appendages occurred almost exclusively in commensal or parasitic nematode taxa. Appendages were discussed based on their relative taxonomic reliability, ecological associations, and distribution in the context of recent 18S ribosomal DNA molecular phylogenetic trees for the nematodes.

  • Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2
    EENY681 Entomopathogenic Nematodes of Thrips Thripinema spp. (Nematoda: Tylenchida: Allantonematidae)1 Danielle Sprague and Joe Funderburk2 Introduction Several species of entomopathogenic nematodes in the genus Thripinema are known to naturally parasitize thrips (Thysanoptera). Thripinema fuscum Tipping and Nguyen is the most common species in Florida (Figure 1). Thripinema fuscum is economically important because it is a natural enemy of the insect pest, the tobacco thrips, Frankliniella fusca (Hinds). Taxonomy The first observation of parasitic nematodes of thrips was made by Uzel (1895) in Europe when an unnamed nema- tode was reported in the body cavity of Thrips physapus L. A nematode inhabiting bean thrips, Heliothrips fasciatus L., was reported in California by Russell (1912), but not described. The first description of parasitic nematodes of thrips was not made until 1932 by Sharga, who described the Figure 1. Thripinema fuscum, female. A) Infective female. B) Anterior nematode Tylenchus aptini from Aptinothrips rufus Gmelin region of infective female. C, D, F) Progressive enlargement of parasitic in England.

A major challenge in the study of Less studied are young obligate symbioses in host lineages that obligate symbioses is to understand how they arise. Because the did not already house obligate symbionts (i.e., “symbiont-naive” best studied obligate symbioses are ancient, it is especially chal- hosts) (10). Some of the best known examples originate through lenging to identify early or intermediate stages. Here we report host manipulation by the symbiont via addiction or reproductive the discovery of a nascent obligate symbiosis in Howardula aor- control. Addiction or dependence may be a common route for onymphium, a well-studied nematode parasite of Drosophila flies.
