dc.description.abstract | Predatory bug, Canthecona furcellata (Wolff.) (Hemiptera: Pentatomidae) is a natural control agent which has been recorded feeding on larvae of many Lepidopterous pests. Studies on the biology of C. furcellata on three lepidopterous insects revealed that maximum fecundity of C. furcellata was 220.8 eggs per female when fed on Corcyra cephalonica Stainton and minimum 121.8 eggs per female on Spilarctia obliqua Walker. while 150 eggs per female on Spodoptera litura. The activity of bug was observed on the Lepidopterous pests in various crops ecosystems viz., soybean(Glycin max(L.)Merr.), blackgram(Vigna mungo (L.) Hepper), greengram(Vigna radiata (L.) R. Wilczek), redgram(Cajanus cajan (L.) Millsp.), dhaincha(Sesbania bispinosa Wt.), groundnut (Arachis hypogaea Linn.), sesame(Sesamum indicum Linn.), castor (Ricinus communis L.), maize (Zea mays L.), brinjal (solanum melongela L.), bhendi(Abelmoschus esculentus (L.)Moench.), and on the plantation tree poplar(Populus deltoides Bartr.ex.Marsh). Studies on population dynamics of C. furcellata revealed its maximum population in Cajanus cajan during 40th standard week. The overall populations of bug in various crops were recorded maximum during 38th standard week. During this period the maximum and minimum temperatures were 29.1 and 22.0 °C and relative humidity was 89 %. Studies revealed that cloudy weather conditions with optimum temperature were favourable for population build up of bug. C. furcellata was observed predating on lepidopterous pests viz., Spodoptera litura, Spilarctia obliqua, Helicoverpa armigera, Trichoplusia ni, Maruca testulalis etc. Studies on predation potential of C. furcellata on different larval instars of S. litura and S. obliqua revealed that the adults were excellent predator in comparison to its nymphal instars. | en_US |
