Abstract

33種のハーブのエタノール抽出液をベニヤ板製のゴキブリのシェルター(5cm×5cm, 5mm隙間)に浸漬させ, チャバネゴキブリ10頭(♂または♀)を放ったプラスチック円形容器(半径15cm, 高さ17cm)に無処理シェルターとともに対角の位置に置いた.それぞれのシェルター区に48時間で落下した糞の数から忌避性を求めた.その結果, デイル, セロリ, キャラウェイ, クミン, コリアンダー(以上, セロリ科), シナモン(クスノキ科), メース(ニクズク科)およびトウガラシ(ナス科)を処理したシェルター区には糞の落下数が極めて少なく, 無処理区のシェルターに90%以上の糞が落下した.これは, これらのハーブを処理したシェルターを忌避したからと判断した.忌避性は1ヵ月以上持続した.また, ハーブ抽出液を80倍程度希釈しても効力は維持した.他方, アニス, サンショ, オニオン, ユーカリなどの抽出液では誘引性が確認された.

Ethanol extracts of some herbs showed strong repellency against the German cockroach, Blattella germanica, under laboratory conditions. Extracts of thirty-three herb species were applied to the surface of cockroach harborages made of 5cm×5cm plywood panels with a 5-mm single void. The majority (90% or more) of cockroach feces was deposited in non-treated harborages when an extract among dill (Anethum graveolens), celery (Apium graveolens), caraway (Carum carvi), cumin (Cuminum cymimum), coriander (Coriandrum sativum), cinnamon (Cinamomum zeylanicum), mace (Myristica fragrans) and chili pepper (Capsicum annuum) was treated on the other side of the harborage in the same arena. The repellent efficacy was sustained with all the above extracts for at least one month, and caraway, cinnamon, chili pepper and celery were effective at 80 times dilution with water. The herbs, anis (Pimpinella anisum), sansyo (Zathoxylum piperitum), onion (Allium cepa), vanilla (Vanilla planifolia), mustard (Brassica hirta) and eucalypt (Eucalyptus radiata), showed an attractant effect to the German cockroach by the same method.
