High levels of inheritable resistance to phosphine in Rhyzopertha dominica have recently been detected in Australia and in an effort to isolate the genes responsible for resistance we have used random amplified DNA fingerprinting (RAF) to produce a genetic linkage map of R. dominica. The map consists of 94 dominant DNA markers with an average distance between markers of 4.6 cM and defines nine ...

ern corn borer resistance. Few plant breeders have access to insect rearing facilities, which are necessary to Southwestern corn borer (Diatraea grandiosella Dyar) and fall maximize selection efficiency. Negative traits tend to armyworm [Spodoptera frugiperda (J.E. Smith)] damage ratings were measured on an F2-derived maize (Zea mays L.) population segregatmask genetic gains in resistance at ea...

The lesser peachtreeborer, Synanthedonpictipes (Grote andRobinson), is an important pest of Prunus spp.We determined the susceptibility of S. pictipes to six entomopathogenic nematode species:Heterorhabditis bacteriophoraPoinar,H. indicaPoinar, Karunakar andDavid,H.marelatusLiu and Berry, Steinernema carpocapsae (Weiser), S. feltiae (Filipjev), and S. riobrave Cabanillas, Poinar and Raulston. N...

The lesser peach tree borer, Synanthedon pictipes (LPTB), belongs to the economically important Lepidopteran family Sesiidae. No studies on genetic variation or population structure on the genus Snyanthedon have been previously published. We examined DNA sequence variation in a 603 bp region of the mitochondrial cytochrome oxidase I gene (COI), tRNA-leu and cytochrome oxidase II gene (COII) fro...

An experiment was conducted during kharif season of 2022-2023 to evaluate the cost benefit ratio by using different insecticidal applications viz., Chlorantraniliprole 18.5 SC (0.5ml/l), Spinosad 45 (0.4ml/l), Nisco sixer plus (2ml/l), Bacillus thuringiensis 4% WSP (2gm/l), Beauveria bassiana 1.15% WP (5gm/l), Neem oil @2% (5ml/l), ½ dose + (2.25ml/l) and Control plot against gram pod borer, He...

Article history: Received on: 15/05/2015 Revised on: 10/06/2015 Accepted on: 17/06/2015 Available online: 20/06/2015 Two field experiments were conducted during Kharif, 2010 and 2011 to find out economical control measures against legume pod borer, Maruca vitrata (Geyer) on pigeonpea. Experimental results showed that the per cent inflorescence damage due to Maruca was lowest in chlorantranilipr...

Abstract Pests and diseases are significant factors that affecting global rice production. There is a need pests have continuously been controlled, in order to solve the pest disease problem. The aim of this study was observe population dynamics infestation lowland field during different cropping seasons. data Pati District, Central Java Province, Indonesia Rainy Season (RS) 2018/2019, Dry (DS)...
