Influence Of Temperature, Relative Humidity And Interspecific Competition On The Population Growth Dynamics Of Three Pests Of Stored Product, Oryzaephilus Surinamensis (L.), Sitophilus Oryzae (L.) And Tribolium Castaneum (Herbst)

Kesan suhu, kelembapan relatif dan persaingan interspesifik ke atas dinamik perkembangan populasi tiga perosak hasil simpanan, Oryzaephilus surinamensis (Linnaeus), Sitophilus oryzae (Linnaeus) dan Tribolium castaneum (Herbst) telah dikaji. Ketiga-tiga spesies ini dipelihara dalam linkungan julat su...

The effects of temperature, relative humidity and interspecific competition on the population growth dynamics of three pests of stored product, Oryzaephilus surinamensis (Linnaeus), Sitophilus oryzae (Linnaeus) and Tribolium castaneum (Herbst) were investigated. These three species were reared under a range of temperatures (26-40°C) and relative humidities (RH) (7-85%). The estimated optimum growth temperature for O. surinamensis, S. oryzae and T. castaneum ranged from 29.61-33.96, 27.63-27.91 and 29.92-33.53°C, respectively, depending on RH. Lethal temperature of T. castaneum was the highest (40°C), followed by O. surinamensis (38°C) and S. oryzae (36°C). S. oryzae were unable to survive at extreme low RH (7%) at all temperatures tested. High RHs were generally beneficial to the population growth of all three species. In an attempt to elucidate the reaction of these species towards RH, water balance studies were carried out. 2015-08 Thesis NonPeerReviewed application/pdf en http://eprints.usm.my/31813/1/GOH_XIN_YU_%28HJ%29.pdf Goh , Xin Yu (2015) Influence Of Temperature, Relative Humidity And Interspecific Competition On The Population Growth Dynamics Of Three Pests Of Stored Product, Oryzaephilus Surinamensis (L.), Sitophilus Oryzae (L.)
