Ecological framework for integrated pest management of fruit flies in papaya orchards

Vargas R.I., . and Stark J.D., . and Nishida T., . (1990) Ecological framework for integrated pest management of fruit flies in papaya orchards. [Proceedings Paper]

Oriental fruit fly OFF Dacus dorsalis Hendel melon fly MF Dacus cucurbitae Coquillett and Mediterranean fruit fly MFF Ceratitis capitata wiedemann survivorship and demographic statistics were compared for experimental F1 populations established on papaya Carica papaya L. fruit under controlled laboratoty conditions. MFF OFF and MF females survived a maximum of 109 123 and 222 d respectively. MFF with the shortest mean generation time and the highest net reproductive rate possessed the highest intrinsic rate of increase. OFF with the second longest mean generation time and the second highest net reproductive rate possessed the second highest rate of increase. MF with the longest mean generation time and the lowest net reproductive rate possessed the lowest intrinsic rate of increase. OFF and MF population dynamics during a 1 yr period were determined from male trap captures in an agricultural area. MFF was not present in the papaya production area. OFF capture rates were higher outside than inside papaya orchard areas. In contrast MF capture rates were higher inside than outside crop production areas. During periods of peak guava abundance numbers of OFF increased in orchards; during periods of peak crop production MF increased in habitats surrounding orchards. Findings are discussed with respect to development of population management strategies in papaya orchards in Hawaii

Abstract

Oriental fruit fly OFF Dacus dorsalis Hendel melon fly MF Dacus cucurbitae Coquillett and Mediterranean fruit fly MFF Ceratitis capitata wiedemann survivorship and demographic statistics were compared for experimental F1 populations established on papaya Carica papaya L. fruit under controlled laboratoty conditions. MFF OFF and MF females survived a maximum of 109 123 and 222 d respectively. MFF with the shortest mean generation time and the highest net reproductive rate possessed the highest intrinsic rate of increase. OFF with the second longest mean generation time and the second highest net reproductive rate possessed the second highest rate of increase. MF with the longest mean generation time and the lowest net reproductive rate possessed the lowest intrinsic rate of increase. OFF and MF population dynamics during a 1 yr period were determined from male trap captures in an agricultural area. MFF was not present in the papaya production area. OFF capture rates were higher outside than inside papaya orchard areas. In contrast MF capture rates were higher inside than outside crop production areas. During periods of peak guava abundance numbers of OFF increased in orchards; during periods of peak crop production MF increased in habitats surrounding orchards. Findings are discussed with respect to development of population management strategies in papaya orchards in Hawaii
