Tetrastichus schoenobii Ferriere is an efficient egg parasitoid on rice yellow stem borer, Scirpophaga incertulas (Walker). The electrophysiological response of females of T. schoenobii to the extracts of plants collected from rice fields was studied under laboratory conditions. The highest response was noticed to the host plant of the pest, S. incertulas and honey solution. Response was also noticed to the flowers of Hyptis suaveolens, a common weed in rice fields, mostly by female parasitoids to the flowers of the non-crop vegetation.

Abstract


Tetrastichus schoenobii Ferriere is an efficient egg parasitoid on rice yellow stem borer, Scirpophaga incertulas (Walker). The electrophysiological response of females of T. schoenobii to the extracts of plants collected from rice fields was studied under laboratory conditions. The highest response was noticed to the host plant of the pest, S. incertulas and honey solution. Response was also noticed to the flowers of Hyptis suaveolens, a common weed in rice fields, mostly by female parasitoids to the flowers of the non-crop vegetation.
