Abstract

A survey of planthopper and leafhopper assemblages and insect predators was conducted in the rice fields of Kaluvanchikudi in Batticaloa District and Kohabana and Central Camp in Amparai District during the dry (yala) season in 1989. Nilaparvata lugens (Stål) was the predominant planthopper species in these rice fields; Sogatella furcifera (Horvath) comprised less than 10% of the sample in any field. The leafhopper species collected included Nephotettix nigropictus (Stål), Nephotettix virescens (Distant), Recilia dorsalis (Motschulsky), and Cofana (=Tettigella) spectra (Distant). Nephotettix species were predominant in Kaluvanchikudi and Kohabana, while R. dorsalis was dominant in Central Camp. Insect predators included the mirid, Cyrtorhinus lividipennis Reuter, an anthocorid, Orius tantillus (Motschulsky) and two coccinellids, Harmonia octomaculata (Fabricius) and Micrapsis discolor (Fabricius). Application of furadan granules reduced the planthopper and leafhopper populations drastically, but did not appreciably reduce the insect predator population.

Résumé

Une étude a été menée sur les Cicadellides, les Fulgorides et les insectes prédateurs collectés dans les riziéres de Kaluvanchikudi dans la région de Batticaloa et de Kohabana et de Central Camp dans la région de Amparai pendant la saison séche (yala) de 1989. Nilaparvata lugens (Stål) a été l’espéce prédominante dans ces riziéres; Sogatella furcifera (Horvath) a représenté moins de 10% de l’échantillon pour toutes les rizières. Les espèces de Cicadellides collectées includent Nephotettix nigropictus Stal, Nephotettix virescens (Distant), Recilia dorsalis (Motschulsky), et Cofana (=Tettigella) spectra (Distant). Les espéces de Nephotettix ont été prédominantes à Kaluvanchikudi et à Kohabana tandis que R. dorsalis a été dominante à Central Camp. Les insectes prédateurs includent le Miride Cyrtorhinus lividipennis Reuter, l’Anthocoride Orius tantillus (Fabricius) et deux Coccinellides Harmonia octomaculata (Fabricius) et Micrapsis discolor (Fabricius). L’application de granules de Furadan a considérablement réduit les populations de Fulgorides et Cicadellides mais pas des insectes prédateurs de façon appréciable.
