Abstract. The Onchocerciasis Control Programme of the World Health Organization uses larvicides to fight against the aquatic stages of the vector Simulium damnosum s.l., and thereby interrupt transmission of the disease.

Since the appearance of resistance to Abate and chlorphoxim in certain cytotypes of the vector, Cited by:   An immediate, catastrophic drift of Simulium spp. on the first treatment day began when the chemical bank reached the sampling riffle.

Significant increases in drift rates of Simulium spp., Glossosoma spp., and Baetis spp. larvae occurred on the evening of the first treatment by: 5.

They found that Simulium damnosum was more difficult to rear from pupae, and sucked blood more rapidly, than Canadian species. They suggest that the full life-cycle of S. damnosum should be studied in detail, and that possible long-term effects of larvicides on fish and Cited by: 8.

First the origins of the pollutants are considered. Secondly, there follows a consideration of laboratory evaluation techniques, and thirdly, the final section of the book looks in detail at a selection of case studies in which the effects on streams of Cited by: I then discuss the effects on the predictions of optimal foraging theory of some common mechanisms by which notonectids avoid their predators.

Because the degree of avoidance is related to the risk of predation I also discuss the possibility that feeding behavior represents an adaptive compromise between the conflicting demands of feeding Cited by: Other Diptera are also important in disease transmission to humans and their animals.

Black flies (family Simuliidae) in the Simulium damnosum species complex transmit onchocerciasis, which is caused by a nematode roundworm, Onchocerca volvulus (Remme, ; Yaméogo et al.,Figures (c) and (d) and (b)).

This document entitled “The Current Status of Freshwater Faunal Diversity in India” is a compendium of 36 chapters, by 48 authors, dealing with the compiled and updated information on the faunal diversity of 19 phyla (18 invertebrate phyla and 01 vertebrate phylum with five classes) of freshwater.

None of Simulium ochraceum s.l. collected in four sentinel communities was found to contain parasite DNA when tested by polymerase chain reaction-enzyme-linked immunosorbent assay (PCR-ELISA), resulting in an upper bound of the infection rate in the vectors of /2, Salinity and temperature requirements for larviculture of the Monkey River prawn Macrobrachium lar (Fabricius, ) (Decapoda: Caridea: Palaemonidae) The present study investigated the effects of salinity and temperature on the survival and development of freshwater (0‰) die within 4 days unless transferred to brackish-water.

The present study demonstrates wide‐ranging effects of 2 common fungicides on an ecologically important species that has a key role in trophic transfer and nutrient recycling in aquatic environments.

These results emphasize the importance of considering the long‐term effects of fungicides in the risk assessment of aquatic by: Aerated microcosms (one-liter glass cylinders) were used to study the effects of biopesticide on algae reproduction (Figure 1).

Thus, we conclude that investigations of the effects of pesticides on a species of interest should go beyond standard toxicological protocols and examine the effects of the pesticide within the context of the community, placing special emphasis on understanding how competition and predation mediate indirect by: Some border control activities, as well as some emergency response actions are now under the jurisdiction of the U.S.
