| 摘 要： | 菠萝粉蚧是为害菠萝的粉蚧的统称,是菠萝凋萎病的主要传播媒介,本文对我国菠萝粉蚧的种类和发生规律进行了研究.结果表明:在我国,为害菠萝的粉蚧主要是菠萝洁粉蚧,仅在海南乐东菠萝园发现有新菠萝灰粉蚧危害；菠萝洁粉蚧目前仅限在菠萝上为害；新菠萝灰粉蚧主要为害剑麻,也为害菠萝和粉蕉;我国暂未发现2种粉蚧混合发生的现象.秋季是雷州半岛地区菠萝洁粉蚧自然种群快速增长期,12月下旬菠萝洁粉蚧自然种群数量进入高峰期；气温和降雨量是影响菠萝洁粉蚧自然种群增长的重要因子,高温、低温均不利于菠萝洁粉蚧生长和繁殖,降雨量对菠萝洁粉蚧的自然种群数量具有明显的抑制作用. |

| Abstract: | Pineapple mealybug is cosmopolitan pest of pineapple and the vector of mealybug wile of pineapple, which is a serious threat to commercial pineapple production. The identification and occurrence rule of Dysmicoccus spp. in China were studied in this paper. The results showed that the pink pineapple mealybug (PPM), Dysmicoccus brevipes was the main mealybug on pineapple in China, and only one pineapple orchard at Ledong in Hainan was found damaged by gray pineapple mealybug(GPM), Dysmicoccus neobrevipes. GPM is mostly addicted to Agave sisalana, but also found on Ananas comosus, and Musa nana occasionally. No complex occurrence of the two pineapple mealybugs was found in the investigation. The natural population of PPM developed fast in autumn, and reached the peak in December in Leichou Peninsula. Temperature and rainfall are the critical factors of population growth of PPM, cold and hot exposure are harmful to the g |
