Acute toxicity of mosquitocidal compounds to young mosquitofish, Gambusia affinis.
Toxicity of Florida mosquito larvicides and adulticides to 3-5 day old Gambusia affinis was determined in the laboratory. After 24-h exposure, the larvicides, temephos, fenoxycarb and petroleum distillates had LC50 values of 5.60, 1.05 and 593.4 ppm, respectively. After 24 h the adulticides resmethrin, fenthion, naled and malathion had LC50 values of 0.007, 2.94, 3.50 and 12.68 ppm, respectivel...
متن کاملTrophic plasticity and fine-grained resource variation in populations of western mosquitofish, Gambusia affinis
Hypothesis: Fish will exhibit morphological plasticity in response to how (food type: live vs. attached food) and where (orientation: surface, mid-water, benthic) they are fed. Fine-grained resource variation (daily rotation of orientations) will produce intermediate morphologies. Population differences will reflect responses to both predators and resources. Organism: Offspring from two populat...
متن کاملPersonality traits and dispersal tendency in the invasive mosquitofish (Gambusia affinis).
Ecological invasions, where non-native species spread to new areas, grow to high densities and have large, negative impacts on ecological communities, are a major worldwide problem. Recent studies suggest that one of the key mechanisms influencing invasion dynamics is personality-dependent dispersal: the tendency for dispersers to have a different personality type than the average from a source...
متن کاملPrey selection by mosquitofish (Gambusia affinis) in California rice fields: effect of vegetation and prey species.
Mosquitofish are widely used for biological control of mosquito larvae in rice fields, but the presence of different types of vegetation or alternative arthropod prey affects the performance of the fish. Feeding experiments were conducted in 4 rice field vegetation zones. Overall, predation was maximal in young and mature rice, moderate in the submerged naiad vegetation, and minimal in areas of...
متن کاملViability Costs of Reproduction and Behavioral Compensation in Western Mosquitofish (Gambusia affinis)
The cost of reproduction hypothesis suggests that current reproduction has inherent tradeoffs with future reproduction. These tradeoffs can be both in the form of energy allocated to current offspring as opposed to somatic maintenance and future reproduction (allocation costs), or as an increase in mortality as a result of morphological or physiological changes related to reproduction (viabilit...
