The copepod Mesocyclops aspericornis Daday and the larvivorous fishes Gambusia affinis (B. & G.) and Poecilia reticulata R. & B., were released into mosquito breeding sites in Tuherahera village, Tikehau atoll, French Polynesia, to control larvae of Aedes aegypti (L.), Ae.polynesiensis Marks, Culex annulirostris Skuse and Cx quinquefasciatus Say. Treatments were completed within a week, in Janu...

workers (Aitken, 1901; Alcock, 1902; Fry, 1912; Hora, 1927; Graves, 1930; Prashad and Hora, 1936; Covell, 1927 and 1941) confirmed the utility of larvivorous fish in India. The Top Minnow extensively used in Italy, South America and West Indies, and imported into India about 1929 from Italy and Siam, has established its reputation as a valuable larvicide.

Human population growth and its associated effects on the environment contribute to rapid decrease of biodiversity worldwide. Artificial light at night (ALAN) is an anthropogenic pollutant that increasing with spread urbanization may declines. ALAN alters migration patterns birds, communication in frogs, impacts reproduction, behavior, physiology multiple other taxa. However, most studies are b...

Somatic growth and reproduction were examined in individual laboratory-grown female Gambusia affinis fed with high (H), medium (M) and low (L) ration levels from birth to the first-time spawning. Results showed that the body length and weight, condition factor (CF), wet weight gain (WG(w)), specific growth rate in wet weight (SGR(w)) and ration levels in terms of energy (RL(e)) decreased signif...
