枸杞实蝇发生的区域差异及不同生产模式的累积效应

Regional Differences in the Occurrence of Neoceratitis asiatica (Becker) and Cumulative Effects of Different Production Modes

研究宁夏各枸杞产区枸杞实蝇发生的区域差异及不同生产模式的累积效应。结果表明,宁夏自北向南8个不同产区不同样地的枸杞实蝇蛹数存在明显差异;不同样地,枸杞实蝇越冬代成虫的羽化始期、第一次羽化高峰期不同;各防控模式下枸杞实蝇蛹的累计量存在差异。

The regional differences in the occurrence of Neoceratitis asiatica(Becker)in different Lycium barbarum producing areas in Ningxia and the cumulative effects of different production modes were studied.The result showed that there were obvious differences in the pupae number of Neoceratitis asiatica(B.)from north to south in 8 different production areas of Ningxia;differently,the emergence beginning and the first peak of the overwintering adults of Neoceratitis asiatica(B.)were different;the cumulative amount of Neoceratitis asiatica(B.)pupae under different control modes was different.
