Abstract

The effect of different doses of Trichosanthes palmata (Makal) seed extract, viz. 1000, 2000, 4000, 8000 and 16000 ppm on the growth and development of Tribolium castaneum and T. confusum was assessed. All the treatments significantly reduced the weight of T. castaneum and T. confusum . Treatments significantly lengthened the larval and pupal periods of both the species. Significantly lower pupal recovery and adult emergence were also observed. DOI: http://dx.doi.org/10.3329/ujzru.v30i0.10735 Univ. j. zool. Rajshahi Univ. Vol. 30, 2011 pp. 17-20

掌角虫种子提取物对木犀草(Tribolium castaneum)和毛犀草(Tribolium confusum jduval)生长发育的影响

研究了不同剂量(1000、2000、4000、8000和16000 ppm)棕榈Trichosanthes palmata (Makal)种子提取物对castaneum和T. confusum生长发育的影响。所有处理均显著降低了木栗和杂色木栗的重量。处理显著延长了两种昆虫的幼虫期和蛹期。蛹恢复率和成虫羽化率也显著降低。DOI: http://dx.doi.org/10.3329/ujzru.v30i0.10735 Univ. j. zool。Rajshahi university . Vol. 30, 2011 pp. 17-20
