摘　　要：本研究旨在探讨槐豆木虱的形态特征及其生物学特性,为该害虫的综合防治提供科学依据。通过若虫蜕皮情况确定其龄期,观察并记录卵至成虫的发育历期、繁殖力及生活习性,利用体视显微镜拍照并测量各发育阶段的形态变化。结果显示,槐豆木虱卵呈纺锤形,长(362.13±3.53)μm、宽(152.06±1.61)μm,初产时呈白色,后逐渐变为橘黄色,透过卵壳可见2个红色小点;卵期(3.81±0.03)d。若虫共5龄,形态特征差异明显。1龄若虫头比腹宽,无翅芽;2龄若虫翅芽初显、较小,前后翅分离;3龄若虫翅芽明显,前后翅芽前期相接不重叠,后期重叠小部分;4龄若虫后翅被前翅重叠一半;5龄若虫前后翅大部分重叠。1~5龄若虫触角节数分别为3、4、6、8、10节,体长分别为(371.82±4.31)μm、(728.15±36.2)μm、(996.9±34.03)μm、(1271.06±24.65)μm和(2083.33±22.89)μm,发育历期分别为(3.81±0.03)d、(3.47±0.06)d、(2.13±0.06)d、(2.03±0.07)d、(2.46±0.06)d和(4.81±0.06)d。成虫触角均为10节,雌成虫尾部呈尖锥状,雄成虫尾部生殖板上翘,夏型雌成虫与雄成虫发育历期分别为(20.88±0.92)d和(28.29±1.67)d。冬型成虫稍大于夏型成虫,冬型与夏型雌成虫体长分别为(4.04±0.12)mm和(3.85±0.24)mm,雄成虫体长分别为(4.02±0.24)mm和(3.31±0.16)mm。夏型雌成虫产卵前期为(5.60±0.24)d,单雌产卵量为(647.75±52.94)粒,雌成虫产卵高峰期在羽化后的第7~14 d,占总产卵量71.2%。综上所述,槐豆木虱若虫共5龄,各龄期间翅芽的发育、触角节数及体长均有显著变化。成虫寿命及产卵期较长,世代之间存在明显的重叠现象,这些发现对于理解其生命周期和制定防治措施具有重要意义。This study aims to delve into the morphological characteristics and biological traits of Cyamophila willieti,providing a foundational reference for integrated pest management.Using molting as the boundary for nymphal instars,we observed and recorded the developmental periods,reproductive capabilities,and behavioral patterns from egg to adult.Photographic documentation and measurements of morphological changes during each developmental stage were conducted using stereomicroscopy.The eggs of Cyamophila willieti are spindle-shaped,measuring(362.13±3.53)µm in length and(152.06±1.61)µm in width.Initially white,the eggs gradually shift to orange,revealing two red spots through the eggshell;the egg stage lasts(3.81±0.03)days.Nymphs undergo five instars with distinct morphological differences.First-instar nymphs have heads wider than the abdomens and lack wing buds;second-instar nymphs show initial and smaller wing buds,with forewings and hind wings separated;third-instar nymphs exhibit well-defined wing buds,with the anterior and posterior wing buds initially adjacent without overlapping,and later partially overlapping;fourth-instar nymphs have hind wings overlapped by half of the forewings;fifth instar nymphs display substantial overlap of both forewings and hind wings.The number of antennal segments for first to fifth instar nymphs is 3,4,6,8,and 10,respectively,and body lengths are(371.82±4.31)µm,(728.15±36.2)µm,(996.9±34.03)µm,(1271.06±24.65)μm,and(2083.33±22.89)µm,with developmental periods for these instars are(3.81±0.03)days,(3.47±0.06)days,(2.13±0.06)days,(2.03±0.07)days,(2.46±0.06)days,and(4.81±0.06)days,respectively.Adults have ten antennal segments,with females having a tapered posterior end and males having an upturned reproductive plate.The developmental periods for summer-type females and males are(20.88±0.92)days and(28.29±1.67)days,respectively.Over wintering adults are slightly larger than summer counterparts.Summer and winter females measure(4.04±0.12)mm and(3.85±0.24)mm,respec
