Model Study of Oriental Fruit Fly （Bactrocera dorsalis Hendel） Occurrence and Dynamic in Citrus Orchard
摘要
Abstract
In order to explore the pattern of oriental fruit fly invasion,dissemination and damage,and improve monitoring and control techniques,the data on annual population dynamics were collected by applying specific sex pheromone traps in 35 monitoring points in the citrus orchard all over 19 communities of Linhai County and 2 systemic monitoring points in Fulong citrus orchard of Gucheng,and Linhai fruit market during 2008-2010.It was found that the temporal and spatial population distribution of oriental fruit fly invasion and dissemination was tower-type in Linhai area,which meant the invasion from the center city spreading to the surrounding area.Population dynamics of oriental fruit fly might usually be described by a single peak curve.The first trap of adult insect appeared between mid-June and mid-July;with the growth inflection point forming in early-August,and the biggest amount of population appeared between September and October.The main factors affecting the population dynamics were population base,climate and habitat conditions.Oriental fruit fly population base （m 6 ） and the annual trapped population （M） might be described by relational model M=23.8339 m 6 ＋59.8003（n=6,r=0.9735 ＊＊ ）.The relationship between 10 days average population density （m n ） and 10 days average temperature in the latest 3 months （t n-9 ） was m n =1.9248t n-9 -14.88063 （n=72,r=0.5123 ＊＊ ）.The relationship models among trapped population of citrus fruiting period （M）,infect rate of plant （R%）,infect rate of fruit （P%）,amount of larvae per fruit （N） were R=0.3667M-1.2746 （n=11,r=0.8901 ＊＊ ）,P=0.0581R＋0.3112 （n=11,r=0.9649 ＊＊ ）,and N=0.6438P＋0.9610 （n=11,r=0.7000 ＊ ）.These models of oriental fruit fly invasion and dissemination could reflect the dynamic changes of oriental fruit fly in citrus orchard and help to make the better forecast and control decision..关键词
