昆虫は palps 食べ物のにおいを検出するために依存して、palps スペシエーション13,27で重要な役割を果たすと考えられています。Palps は単純な嗅覚器官であり、脳分子の探査のための魅力的なモデルは、基になるその28をネットワークとして注目を受けています。
昆虫昆虫および palp SSRs 正常に行った、キイ?...

動物には、外因性化学手掛かりを感じる嗅覚器官の範囲が進化してきました。昆虫で最も重要な嗅覚器官がアンテナと palps です。これらの臓器に嗅覚の触角と呼ばれる、化学感覚毛のいくつかの種類は、毛の嗅覚ニューロン (CSNs) によって支配されています。嗅覚の触角の CSNs 認識中枢神経系1,報2,3 まで転送されるその後の電位に化学的刺激に対するシグナル伝達を介して特定の化学手掛かり.
CSNs エクスプレス様々 な嗅覚受容 [例えば、嗅覚受容体 (ORs)]、イオン型受容体 (IRs) とそのの種類に関連付けられている外因性化学手掛かりをエンコード、膜上の味覚受容体 (GRs)4,5,6。CSNs の特性は、昆虫化学受容の分子・細胞メカニズムの解明への鍵です。蛾8、甲虫9、アブラムシ10, イナゴ11, 単一ゴキブリ記録 (SSR) など多くの昆虫の触角感覚の昆虫 CSNs のキャラクタリゼーション ハエ7のため広く使われている手法ですが、今とアリ12。その触角の特定の構造を作るのでただし、いくつかの研究、SSR 昆虫 palps13,14,15,16,17に適用が、電気生理学的記録困難18。
イナゴ (直翅目) は、しばしば深刻な農作物被害と経済的損失19を引き起こします。Palps はイナゴ20,21,22,23,24の食品の選択に重要な役割を果たすと考えられています。走査型電子顕微鏡 (SEM)、嗅覚の触角の 2 種類を調べた。通常、イナゴ palps18の各ドーム、350 触角 chaetica と 7-8 触角 basiconica を観察します。触角 chaetica が非揮発性化学手掛かりを感じる味覚のワモンゴキブリ触角 basiconica 揮発性化学手掛かりを感知、嗅覚機能があります。
イナゴ palps 触角 basiconica (ca. 12 μ m) の髪ソケットの直径は触角 chaetica のそれらよりはるかに大きい (ca. 8 μ m)18,25。Palps で触角 basiconica のクチクラの壁は触角感覚18のそれよりもはるかに厚いです。さらに、palp のドームは柔軟性の高いキューティクル内流体の内容です。これらの特性は、電極と良好な電気生理学的信号の集録と浸透が触角感覚のよりも難しいという意味します。本稿でビデオ イナゴ palp 触角 basiconica の詳細と非常に効果的な SSR のプロトコルが表示されます。
