After first treatment, reduction within 1 week of 3 species of cladocerans (Daphnia laevis, Ceriodaphnia sp., Bosmina longirostus sp.), and 2 species of copepods (Cyclops sp., Diaptomus sp.). No recovery of Daphnia and Ceriodaphnia for 6 months, but Bosmina reappeared 11 weeks later. Diaptomus was depleted for 4 months, but Cyclops recovered in 6-7 weeks. The amphipod Hyallela azteca was eliminated within 4 weeks, and no recolonization was evident after 6 months. No adverse effects on oligochaetes, snails (Physa sp.), or ostracods (Cyprodopsis sp.). After second treatment, temporary reduction in Cyclops and Bosmina, and no significant effects on ostracods, snails, or worms...

Invertebrate species have been widely used in toxicity studies of pesticides [61]. Zooplankton play a key role in the food chain because they occupy a central position. Therefore, their responses to natural and anthropogenic stresses are intimately linked with other food predator organisms. The most widely accepted bioassays employ species such as Ceriodaphnia dubia, Daphnia magna, Artemia salina, or Thamnocephalus platyurus [62-64]. D. magna has been used for many years as a standard aquatic test species and formally endorsed by the major international organizations such as the EEC, OECD, and ASTM [65-67]. Its choice is mainly because it represents the zooplankton community and is a species of worldwide occurrence. In addition, it has a greater sensitivity to toxicants, particularly pesticides, compared with other aquatic species [61,68] (Table 1).

In addition to acute toxicity tests, two standard chronic toxicity test methods are widely accepted by various regulatory agencies the seven-day Ceriodaphnia survival and reproduction test and the 21-day Daphnia reproduction test.
