(Neuroptera: Chrysopidae) for egg laying under laboratory conditions JF - Journal of Biological Control JA - JBC VL - 35 IS - 4 SE - Research Notes DO - 10.18311/jbc/2021/29020 UR - https://informaticsjournals.com/index.php/jbc/article/view/29020 SP - 277-280 AB - <p>Colour preference of female green lace wing, <em>Chrysoperla</em> sp. (Neuroptera: Chrysopidae) for egg laying under laboratory conditions were tested in the Bio-control Laboratory, IGKV, Raipur during 2018-19. Females of <em>Chrysoperla</em> sp. visually distinguished different colours <em>viz</em>., green, white, brown, black, red and pink coloured substrate for egg laying. In the present studies, among the colours tested, <em>Chrysoperla</em> sp. females preferred black colour as substrate for egg laying and laid an average maximum of 36.36 eggs followed by green colour (31.78), white colour (22.94), pink colour (20.81), red colour (20.42), brown colour (14.00), respectively. Thus, for the mass multiplication of <em>Chrysoperla</em> sp., under laboratory conditions, black coloured cloth/paper can be used.</p> ER -
