  • Hydrilla Verticillata Threatens South African Waters
    Hydrilla verticillata threatens South African waters J.A. Coetzee1 and P.T. Madeira2 Summary South Africa’s inland water systems are currently under threat from hydrilla, Hydrilla verticillata L. Royle (Hydrocharitaceae), the worst submerged aquatic weed in the USA. The presence of the weed was confirmed for the first time in South Africa in February 2006, on Pongolapoort Dam in KwaZulu-Natal. An aerial survey revealed that the infestation on this dam covers approximately 600 ha, which is far greater than initially thought. Despite reports that it may be present in other water bodies, surveys have shown that it is restricted to Pongolapoort Dam. We conducted a boater survey which showed that there is significant potential for this devastating weed to spread beyond Pongo- lapoort Dam, and containment of hydrilla is of utmost priority. Research into the suitability of the already established biological control agents, Hydrellia pakistanae Deonier and H. balciunasi Bock (Diptera: Ephydridae), from the USA, as potential agents in South Africa, is also being conducted. However, the South African hydrilla biotype is different from the biotypes in the USA, and this needs to be borne in mind when considering which agents to release. Keywords: potential spread, management, genetic analysis. Introduction Current distribution of The confirmation of Hydrilla verticillata L. Royle hydrilla in South Africa (Hydrocharitaceae) (hydrilla) in South Africa from and potential for spread Pongolapoort Dam, KwaZulu-Natal province (KZN), in early 2006 (L.

  • The Anal Plates of Larval Hydrellia Pakistanae (Diptera: Ephydridae)
    82 Florida Entomologist (95)1 March 2012 THE ANAL PLATES OF LARVAL HYDRELLIA PAKISTANAE (DIPTERA: EPHYDRIDAE) BRIAN DURHAM AND MICHAEL J. GRODOWITZ U.S. Army Engineer Research and Development Center, 3909 Halls Ferry Road, Vicksburg, MS, 39180 Abstract The objective of this research was to describe the anal plates of the larval stages of the ephydrid fly,Hydrellia pakistanae Deonier, a biological control agent of hydrilla (Hydrilla verticillata (L.f.) Royle). This was accomplished using light microscopy coupled with a spe- cialized staining technique; and scanning electron microscopy (SEM). All 3 instars of H. pakistanae were collected from hydrilla cultured in outdoor concrete-lined ponds. To ascribe a function to the anal plates, a modified staining technique was employed that uses a 5% silver nitrate solution, which, upon ionization, binds with chloride ions suggesting an os- moregulatory function. Under light microscopy the two anal plates appeared smooth, flat crescent moon-shaped structures that encircled the anus of the larva. SEM revealed the anal plates to be relatively smooth with an undulating surface pattern possibly an artifact of the high vacuum conditions associated with the SEM. This may therefore indicate a difference in cuticle thickness for the anal plates since the overall body cuticle did not exhibit the same surface changes. A distinct delineation in the form of a thin raised line of cuticle between the anal plates and the outer body cuticle could be discerned from both light microscopy and SEM. The anal plates vary in size from 200 µm to 750 µm in perimeter and 1800 µm² to 14000 µm² in area depending on instar.

As a consequence, I have decided to nominate him for the ESA SEB Recognition Award in IPM and believe he is deserving of your strongest consideration. Jim has developed an internationally recognized program in biocontrol of invasive weeds and has become a globally recognized authority in identifying and evaluating potential biocontrol agents of invasive weeds. He has made significant contributions to the successful management of important invasive weed species in both aquatic and terrestrial environments. He also has made important discoveries in understanding the attributes of successful introduction of exotic biocontrol agents in a manner that successfully mitigates the invasion without disruption of native species. Information from this work has been critical to the management of important invasive plant species such as the tropical soda apple.
