 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Effects of Gramma Radiation on Azuki Bean Weevil, Callosobruchus chinensis (L.)) ผู้เขียน: จักรพงษ์ สุภาวรรณ์,  ดร.ประภารัจ หอมจันทน์, ศาสตราจารย์ , Manon Sutantawong, นางอรุณี วงศ์ปิยะสถิตย์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractEffects of gamma radiation at various doses on eggs, larvae, pupae and adults of azuki bean weevil, Callosobruchus chinensis (L.) were studied. It was found that there were no significant differences between percent egg mortalities at 40 and 80 Gy and among 120, 160 and 180 Gy. As for the larvae, percent mortalities at all doses were significantly different from that of the control. Significant differences were also found among tested doses from that of the control in percent pupal mortality. After 4 and 7 days of irradiation, percent adult mortalities were found to be significantly different from those of the control at every dose. No significant differences were found among percent mortalities at all tested doses between 4 and 7 days. Percent sterilities at 100 and 120 Gy were not significantly different. When untreated male mating with treated female, there were significant differences in fecundity from the control and from among one another. In treated larvae at 100, 300 and 500 Gy, of all doses the degrees of melanization decreased with the increasing dose. The percent phenoloxidase (PO) activities of the treated larvae reduced compared with that of the control. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Checklist of New Records of Subfamily Lamiinae (Coleoptera: Cerambycidae) in Northern Thailand) ผู้เขียน:สุขสวัสดิ์ พลพินิจ, ผู้ช่วยศาสตราจารย์ , ดร.ประภารัจ หอมจันทน์, ศาสตราจารย์, นางวาลุลี โรจนวงศ์, ผู้ช่วยศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractCollections were made of longhorn beetles, subfamily Lamiinae (Coleoptera: Cerambycidae), during 2004–2008 from specimens caught on flowers, trees and light traps from northern Thailand for taxonomic studies. Specimens were compared with samples from the Department of Agriculture, Royal Forest Department, Kasetsart University, the private collection of Bro. Amnauy Pinratana and by expert identification. The results revealed 47 newly recorded species in northern Thailand—namely, Agelasta bifasciana, Anamera desemaculata, A. obesa, A. strandi, Anameromorpha metallica, Annamanum chebanum, Anoplophora birmanica, A. medenbachii, A. stanleyana, Astathes violaceipennis, Batocera thomsonii, Blepephaeus ocellatus, Cleptometopus similis, Choeromorpha subfasciata, Cylindrepomus viridipennis, Driopea luteolineata, Epicedia maculatrix, Eutaenia albomaculata, Glenea mathemalica, G. quadrinotata, G. subviridescens, G. vaga, Gnoma gilmouri, Hirtaeschopalaea fasciculata, Hoplothrix rivulosus, Mispila kamvengal, Monochamus guerryi, Nipholophia chujoi, Nupserha spinifera, Olenecamptus fouqueti, Parachydaeopsis laosica, Pharsalia duplicata, P. pulchroides, Phrissomorimus brunneus, Pterolophia bituberculatithorax, P. humerosa, P. mimoconsularis, P. paralaosensis, P. partealbicollis, Rhodopina griseipes, Serixia apicefuscipennis, Sthenias franciscana, Stibara humeralis, S. subpunctata, Thylactus uniformis, Trachystohammus subelongatus and Xenolea asiatica. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Gamma-Irradiation Induced Alterations in Mungbean ?-amylase Inhibitory Activities : Effects on ?-amylase and Development of Mungbean Weevil (Callosobruchus maculatus)) ผู้เขียน:ดร.อรุณี อิงคากุล, ผู้ช่วยศาสตราจารย์, ดร.ประภารัจ หอมจันทน์, ศาสตราจารย์, นางอรุณี วงศ์ปิยะสถิตย์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractCrude ?-amylase inhibitors, the protein and the non-protein parts, were extracted from seeds of standard mungbean varieties KPS1 and CN36 and the mutant lines M5-16 and M5-29, derived from CN36 by gamma-irradiation. Only the protein part was found to produce substantial inhibition when tested against ?-amylase from adult mungbean weevil (Callosobruchus maculatus) and barley malt (Type VIIIA) with 4-5 times greater percentage inhibition by the extracts from the mutants than those from the standard varieties. In the in vivo study, feeding larval C. maculatus with seeds of KPS1 and M5-29 treated with 0.5% solution of the proteinaceous inhibitor extracted from M5-16 resulted in a significant reduction in the average number of emerging adults. The effects of the two standard varieties and the two mutant lines seeds, with and without seed coats, on two parameters related to the development of the weevil ie., the average number of eggs laid and the number of emerging adults, were also investigated. No significant differences were found in the average numbers of egg laid on seeds, with and without seed coats, of all varieties/lines. However, significant reduction in the average number of emerging adults were observed in mutant seeds, with or without seed coats, as compared with the standards. |
