Comparison of different materials as Helicoverpa armigera (Hübner) oviposition substrates
International Journal of Tropical Insect Science 24 (4), 336-339
Abstract: In studies aimed at optimizing the substrate for rearing Helicoverpa armigera (Hübner) under laboratory conditions, the noctuid's oviposition behaviour was studied in the laboratory using pigeonpea leaves, muslin cloth, tissue paper and cotton wool as oviposition substrates in free-choice and no-choice tests. Egg counts revealed the moth's preference for oviposition substrate, in descending order, to be cotton wool, pigeonpea leaves, tissue paper and muslin cloth. The preference index of cotton wool was 65% higher than the least preferred substrate, muslin cloth. A total of 300 eggs per female were laid in the free-choice tests, while 200 were laid in the no-choice assays.

Des études ont été menées en conditions de laboratoire afin d'améliorer le substrat d'élevage d´Helicoverpa armigera (Hübner). Le comportement d'oviposition a été étudié en situation de choix et de non choix sur différents substrats, des feuilles de pois d'angole, de la mousseline, du tissu de papier et du coton absorbant. Le dénombrement des oeufs montrent une préférence d'oviposition décroissante du coton absorbant vers les feuilles du pois d'angole, le tissu de papier et la mousseline. L'indice de préférence du coton absorbant est 65% plus élevé que celui du substrat le moins préféré. En situation de choix les femelles ont pondu en moyenne 300 oeufs alors qu'en situation de non choix elles en ont pondu 200.
