“…The higher sensitivity of the hatching test than acute one was found for copper sulphate pentahydrate, by using the same hatching protocol (Manfra Guzzella et al 1997Guzzella et al et al 2015b. Moreover, comparable EC 50 values, for both DEG and SDS, were obtained with acute tests on other marine species, known to be more sensitive than Artemia (Table 3).…”

Artemia sp. is extensively used in ecotoxicity testing, despite criticisms inherent to both acute and long-term tests. Alternative endpoints and procedures should be considered to support the use of this biological model. The hatching process comprises several developmental steps and the cyst hatchability seems acceptable as endpoint criterion. In this study, we assessed the reliability of the hatching assay on A. franciscana by comparing with acute and long-term mortality tests, using two chemicals: Diethylene Glycol (DEG), Sodium Dodecyl Sulphate (SDS). Both DEG and SDS tests demonstrated a dose dependent hatching inhibition. The hatching test resulted more sensitive than acute mortality test and less sensitive than the long-term one. Results demonstrate the reliability and high sensitivity of this hatching assay on a short time lag and support its useful application in first-tier risk assessment procedures.

“…1). The organophosphates registered for mosquito control are broad spectrum insecticides and are highly toxic to a range of insects including Chironomidae, Ephemeroptera, Coleoptera, Hymenoptera and Arachnids (Mulla & Khasawinah 1969;Porter & Goimerac 1969;Hurlbert et al 1972;Didia et al 1975) as well as Crustacea including shrimp (Ludwig et al 1968;Mortimer & Chapman 1995;Brown et al 1996;Guzzella et al 1997;Key et al 1998) andCladocera (Didia et al 1975). Organophosphates have also been recorded to exert significant mammalian toxicity (Costa 2006).…”

Our review outlines changes in insecticide usage for mosquito control against Australian mosquitoes, with a focus on biologically based insecticides. The most widely used microbial insecticide is Bacillus thuringiensis var. israelensis de Barjac (Bti) and it is regularly used in estuaries and freshwater. In comparison, the use of Bacillus sphaericus (Neide) is limited to freshwater. The only insect growth regulator registered for mosquito control in Australia is s-methoprene, and it is used in both estuaries and freshwater. Although biologically based insecticides have been used for more than 10 years, there remains knowledge gaps surrounding the use of specific formulations in specific habitats: for example, VectoBac WG (Bti) and VectoBac G (Bti) in containers containing freshwater, or Altosid pellets (s-methoprene) in ground-pool freshwater habitats. Where broad-scale mosquito control programs have been implemented in Australia, a reduction in the incidence of mosquito-borne disease, mainly Ross River virus, has been recorded. Therefore, the future application of these products is supported. The use of insecticides should be integrated with public education, biological control, physical habitat modification and coupled with spatial risk assessment.

“…Other authors who worked with Brachionus sp., a rotifer, and Artemia sp. have reported similar LC values for parathion, malathion, azinphosmethyl, and chlorpyrifos (Guzzella et al, 1997), although these authors used high purity pesticides. However, the acute toxicity values of these pesticides reported for freshwater invertebrates are lower than those found in this work (Fernandez et al, 1992).…”
