高温对叉角厉蝽生长发育及繁殖的影响
Effects of high temperature on the growth,development and reproduction of Eocanthecona furcellata(Hemiptera:Pentatomidae)
摘要
Abstract
[Objective]To clarify the effects of different high temperature environment on the growth,development and reproduction of Eocanthecona furcellata,which could provide theoretical basis for the application of Eocanthecona furcellata in high-temperature tea plantations environments in summer.[Method]Different high-temperature environments in tea plantations were simulated using an artificial climate chamber.Constant temperature treatments[25(CK),37 and 40℃]and fluctuating temperature treatments(25-37℃and 25-40℃)were set to impose stress on Eocanthecona furcel-lata.The age-stage two-sex life table was adopted to analyze life table parameters of Eocanthecona furcellata,including growth and development,fecundity and survival rate.[Result]High temperature exerted great effects on the growth,de-velopment and reproduction of Eocanthecona furcellata.Under constant temperatures of 37 and 40℃,Eocanthecona fur-cellata failed to complete normal growth and development.Under fluctuating temperature regimes of 25-37℃and 25-40℃,the developmental duration of the egg stage and each nymphal instar were significantly shortened by 1-2 d com-pared with CK(P<0.05,the same below).The nymphal survival rate of Eocanthecona furcellata was the highest in CK,with the survival rate of the 5th instar nymph reaching up to 87.5%.In contrast,under the fluctuating temperature treat-ments of 25-37℃and 25-40℃,the maximum survival rates of the 5th instar nymph were only 75.0%and 72.5%respec-tively.In addition,under the fluctuating temperature of 25-37℃,female adult longevity(25.29 d)and oviposition period(15.88 d)were the longest and significantly longer than those in CK.The highest egg laid by per female was recorded under this treatment,with 179.82 eggs per female,which was 14.54%higher than CK.Moreover,the intrinsic rate of increase(0.118 d-1)and finite rate of increase(1.124 d-1)under 25-37℃fluctuating temperature were significantly higher than those of CK,while the mean generation time(36.890 d)was significantly shorter than CK.[Conclusion]High temperature conditions in tea plantations in mountainous regions during summer are suitable for colony establish-ment and progeny development of Eocanthecona furcellata.Eocanthecona furcellata is suitable for biological control of pests in tea plantations in mountainous regions and can exert long-term control effects on tea garden pests.关键词
