作者记述了为害橄榄的重要害虫橄榄星室木虱(Pseudophacopteron canarium Yang&Li)的生物学特性、种群数量动态及其天敌种类资源。该虫在福州地区1年发生7～9代,没有明显的越冬现象。翌年2月下旬、3月上旬产卵于嫩芽上,3月上旬出现若虫,第1代成虫始见于3月下旬,世代重叠。橄榄星室木虱田间种群数量消长与橄榄抽梢期有极其密切的伴随关系,在幼树上全年有5个虫口高峰期,在老树上全年只有3个高峰期。在实验室23.0～25.0℃的平均温度下,卵期4.1—4.7天,若虫期10.4～13.5天,世代历期20～28天,世代死亡率为64.53％。成虫平均寿命41.4±4.6天,产卵前期7.2±2.2天,产卵期18.0±3.7天,每雌平均产卵量276.3±64.0个。雌雄性比为1.17:1。红基盘瓢虫、红星盘瓢虫是该虫的优势捕食性天敌。喷药保梢是该虫猖獗发生年综合治理的关键措施。
The authors described the biological characteristics, population dynamics, and natural enemies of Pseudophacopteron canarium Yang & Li, an important pest of olive. The insects occurred in Fuzhou area 7-9 generations a year, there is no obvious phenomenon of overwintering. The following year in late February, early March spawning in the tender, nymphs appear in early March, the first generation of adults first seen in late March, generations overlap. The population growth and decline of Oligostromes in the field are closely related to the shoot extinction period. In the sapling, there are 5 peak periods in the whole year and only 3 peak periods in the old tree. Under the average temperature of 23.0 ~ 25.0 ℃ in the laboratory, the egg stage was 4.1-4.7 days and the nymphal stage was 10.4 ~ 13.5 days. The generational duration was 20-28 days, and the death rate was 64.53%. The average life expectancy of adult was 41.4 ± 4.6 days, 7.2 ± 2.2 days in pre-oviposition, 18.0 ± 3.7 days in oviposition, and 276.3 ± 64.0 in females. Male to female ratio was 1.17: 1. Red base ladybug, Red Star dish Ladybug is the predatory predator of the insect. Spraying Baotao is the pest rampant annual comprehensive control of the key measures.
