objective: in this study the efficacy of two agent of this biological control agent of corn stem borer in corn fields compared with common synthetic insecticides endosolfan to find a suitable alternative for chemical control of pests in corn fields. methods: in order to evaluate the efficiency of biocontrol agents of corn stem borer ,ostrinia nubilalis, experiment was conducted in a randomized ...

the aim of the research was analysis of rice producers’ perceptions of participatory communication in the use of integrated pest management (ipm). research population was consisted of rice producers in the west of mazandaran province (n=16126), whose 187 ones were selected using cochran’s formula. data were gathered by systematic random sampling method. the instrument for data collection was a ...

Differences in pest management of olive orchards may affect the development of olive trees and may be reflected in terms of absolute and relative asymmetry, mass, and quality of the leaves. Leaf mass and residual leaf mass of olive trees were significantly greater under organic management than other pest management regimes. The analysis revealed that leaves from trees under different pest manag...

Pest index, a new approach to categorizing the threat posed by an organism to woody plants, is proposed to assist plant managers in establishing treatment thresholds for pests of woody plants. The need for such a tool is based on the incredible diversity of pests of woody plants and the lack of experimental data establishing such thresholds. The pest index is computed using information about th...

Integrated Pest Management (IPM) has had a varied history, with different definitions. It has been implemented under an array of different connotations (Lewis et al., 1997). The term was earlier used as ‘‘integrated control’’ by Bartlett (Bartlett, 1956) and was further elaborated on by Stern and co-workers (Stern et al., 1959). In reference to the concept of integrating the use of bio‐ logical...

the study was conducted among the two farmer groups in bhaktapur and kavre districts of nepal. the main objective of the study is to evaluate the differences in belief, attitude and practices felt by the farmers after participation in the ipm ffs. the study has been based on data collected through personal interview with the farmers, focus group discussion, personal observation in the farmers f...

Timely availability of expert support to the farmers for appropriate decision-making on ‘whether and what pest management option is required’ is imperative for effective Integrated Pest Management (IPM). For several decades Economic Threshold Level (ETL) has been the basis for decision-making but in modern IPM emphasis is given on agro-ecological situation wherein IPM decisions are based on lar...

A key component of Integrated Pest Management (IPM) in agricultural systems is ®eld monitoring for pests prior to reaching a management decision. The study objective was to quantify a common design constraint of commercial IPM sampling programs: the trade-o€ between sampling time and accuracy of the resulting pest management decision. Using consperse stink bug (Euschistus conspersus Uhler) in p...
