Abstract
|
|
|
Laboratory evaluations of mosquito-fishes and invertebrate predators on their predation effectiveness against mosquito larvae were conducted in 1976. A total of 5 different species of candidate mosquito-fishes, Zacco platypus, Aprochelus latipes, Poecilia lecticulatus, Macropodus chinensis and Lefua costata, and 3 species of invertebrate predators, Dugesia jponica, D. dorotocephala and hydra sp. were tested against 3rd instar C. pipiens larvae.
Among fish-predators, the most effective fish was Zacco platypus showing the rate of mosquito reduction 98.0%, followed by Aprochelus latipes 97.5%, Other fishes demonstracted lower destructive capacities, which ranged Poecilia lecticulatus 58.7%, Lefua costata 80.0% and Macorpodus chinensis 68.7%. Among invertebrate predators, degesia derotocephala from Riverside was most effective, showing 97.5% of mosquito destruction rate, followed by D. japonica from Chang-gok 91.0%, D. japonica of HIH strain showed only 86.5%. Hydra sp. from Chang-gok rice paddy demonstrated higher rate of mosquiot reduction with 93.5% when compared with Hydra sp. from river seepage in Seoul with 83.0%. Various species and strains of predators were compared to elaborate the efectiveness of biological control possibilities against mosquitoes.
