モモシンクイガの発育に及ぼす恒温条件の影響 Effect of constant temperatures on the development of peach fruit moth, Carposina sasakii (Lepidoptera: Carposinidae) 豊島, 真吾 トヨシマ, シンゴ TOYOSHIMA, Shimgo 新井, 朋徳 アライ, トモノリ ARAI, Tomonori YAGINUMA, Katsuhiko 栁沼, 勝彦 ヤギヌマ, カツヒコ 柳沼, 勝彦 peach fruit moth apple development lower developmental threshold thermal　constant peach fruit moth apple development lower developmental threshold thermal　constant The temperature-dependent development of Carposina sasakii was investigated to estimate the lower developmental thresholds and thermal constants. C. sasakii was reared in immature apple fruits ('Fuji') for larval stage and in soil for pupal stage at 7 constant temperatures in the laboratory. Larvae and pupae survived well in fruits and soil at each temperature, except for pupae at 25ºC. Developmental periods from egg to adult in female was longest at 15ºC (90.3 ± 0.9 days) and shortest at 27.5ºC (27.4 ± 0.2 days). The regression equations between developmental rates from egg to adult molt (y) and temperature (x) were estimated as y = - 0.0206 + 0.0021x (r＾2=0.98)　for females and y = - 0.0203 + 0.0020x (r＾2=0.98) for males. The lower developmental thresholds　and thermal constants in the immature stage were estimated as 10.0ºC and 484.2 degree-days for　females and 9.9ºC and 488.0 degree-days for males, respectively. 発育を完了した個体のデータを元にモモシンクイガの発育零点と有効積算温量を推定するため，収穫した幼果（' ふじ'）と園芸培養土でモモシンクイガを飼育して７種の恒温条件における発育特性を調査した．25℃における蛹ステージを除いて，幼虫と蛹はよく発育した．卵から羽化までの発育期間は，15ºC でもっとも長く（90.3± 0.9 日），27.5ºC でもっとも短かった（27.4 ± 0.2日）．温度（x）に対する卵から羽化までの発育速度（y）の回帰式は，雌でy = -0.0206 + 0.0021x（ r＾2=0.98），雄で y = -0.0203 + 0.0020x（ r＾2=0.98） であった．全発育間における発育零点と有効積算温量は，雌で10.0℃と484.2 温日度，雄で9.9℃と488 温日度であった． 独立行政法人 農業・食品産業技術総合研究機構 果樹研究所 2010-03-01 eng departmental bulletin paper VoR https://doi.org/10.24514/00001927 https://repository.naro.go.jp/records/2012 10.24514/00001927 10.24514/00001927 1347-3549 果樹研究所研究報告 Bulletin of the National Institute of Fruit Tree Science 10 1 8 https://repository.naro.go.jp/record/2012/files/nifs_report_No10p1-8p.pdf application/pdf 405.0 kB 2019-03-19
