“…In an earlier study, a group researcher reported 24hr LC50 value of 81.5 ppm for Malathion to the freshwater anostracan, Streptocephalus proboscidius nauplii [41]. A group of scientists have found 24hr LC50 value of 67.7 ppm for Malathion to S. sudanicus nauplii [42]. However, some of them reported 24hr LC50 value of 6.4 ppm for Malathion to S. proboscidius nauplii [43].…”

Present investigation discusses the toxic effects of two organophosphorus pesticides (Malathion) and (Glyphosate) on brine shrimp, Artemia in static acute toxicity tests (24hr and 48hr). Toxicity tests were performed at a temperature of 27±1⁰C with a photoperiod of 12h light and 12h dark. Ten healthy nauplii were exposed to five different concentrations of Malathion (10, 20, 40, 60 and 80 ppm) and Glyphosate (0.01, 0.02, 0.03, 0.04 and 0.05 ppm) along with a control group. Finney's Probit analysis was used to determine the 24h/48h LC50 values and were found to be 58.3 and 17.3 ppm, 0.028 and 0.019 ppm for Malathion and Glyphosate, respectively. Of the two pesticides tested Glyphosate was found to be significantly more toxic to Artemia nauplii than that of Malathion (P < 0.05).

“…Besides the fairy shrimps mentioned above, Lahr et al (2001) recommended the backswimmer Anisops sardeus for local risk assessment and obtained repeatable results with this insect, which was also highly sensitive to most of the insecticides tested. Static acute toxicity tests with both species, which were captured in the field, gave repeatable results and tests appeared relatively easy to carry out (Lahr et al 2001).…”

“…Lower noted sensitivities of indigenous tropical species compared to temperate test species, ecological significance and/or economic value are reported as underlying reasons for this need (Widianarko et al 1994;Castillo et al 1997;Lahr et al 2001;Do Hong et al 2004;Lopes et al 2007).…”

“…Caridina africana, one of the most widespread shrimp species in inter-tropical Africa, was found to be considerably more sensitive to the larvicide etofenprox than Oreochromis niloticus and Tilapia zilli (Yaméogo et al 2001). The fairy shrimp Streptocephalus sudanicus was concluded to be important in evaluating possible effects of insecticides on temporary ponds in the Sahel because they are very typical for this habitat, differed highly in their response to insecticides compared to Daphnia magna and recovered extremely slow compared to many other invertebrate groups (Lahr et al 2000(Lahr et al , 2001.…”

Implications of differences between temperate and tropical freshwater ecosystems for the ecological risk assessment of pesticides

2009

Despite considerable increased pesticide use over the past decades, little research has been done into their fate and effects in surface waters in tropical regions. In the present review, possible differences in response between temperate and tropical freshwaters to pesticide stress are discussed. Three underlying mechanisms for these differences are distinguished: (1) climate related parameters, (2) ecosystem sensitivity, and (3) agricultural practices. Pesticide dissipation rates and vulnerability of freshwaters appear not to be consistently higher or lower in tropical regions compared to their temperate counterparts. However, differences in fate and effects may occur for individual pesticides and taxa. Furthermore, intensive agricultural practices in tropical countries lead to a higher input of pesticides and spread of contamination over watersheds. Field studies in tropical farms on pesticide fate in the enclosed and surrounding waterways are recommended, which should ultimately lead to the development of surface water scenarios for tropical countries like developed by the Forum for the co-ordination of pesticide fate models and their use for temperate regions. Future tropical effect assessment studies should evaluate whether specific tropical taxa, not represented by the current standard test species in use, are at risk. If so, tropical model ecosystem studies evaluating pesticide concentration ranges need to be conducted to validate whether selected surrogate indigenous test species are representative for local tropical freshwater ecosystems.

“…Previously, these entomopathogenic fungi have been shown to kill a wide variety of invertebrates, but also fish and reptiles (5-7). In addition, M. anisopliae is toxic to two indigenous African Sahel invertebrates, the fairy shrimp Streptocephalus sudanicus and the backswimmer Anisops sardeus (8). Worryingly, B. bassiana can infect immunosuppressed people (9, 10), a particular concern in many of the malariaendemic regions of sub-Saharan Africa with high HIV/AIDS prevalences.…”
