counting the population of insect pests is a key task for planning a successful integrated pest management program. most image processing and machine vision techniques in the literature are very site-specific and cannot be easily re-usable because their performances are highly related to their ground truth data. in this article a new unsupervised image processing method is proposed which is gen...

flea beetles of chaetocnema tibialis (col:, chrysomelidae) are important pests on sugar beet iniran. in some cases, the damages caused by this pest are so high that some part of  the field should be replanted. since most of crop losses occur from cotyledon stage until 4-leaf stage, monitoring of the population of this pest could play an important role in decreasing damage of the pest. sticky-co...

the wood boring beetle, chrysobothris affinis is the most destructive pest of albezia lebeck in landscape of ahwaz. population fluctuations of the pest were investigated on albezia lebbeck in ahwaz landscape during 2010 - 2011. sampling was monthly performed. in each sampling date, ten trees were randomly chosen and damage symptoms of the pest were monitored. when damage symptoms observed in st...

Pest insects pose a significant threat to food production worldwide resulting in annual losses worth hundreds of billions of dollars. Pest control attempts to prevent pest outbreaks that could otherwise destroy a sward. It is good practice in integrated pest management to recommend control actions (usually pesticides application) only when the pest density exceeds a certain threshold. Accurate ...

Pest monitoring is time consuming and labor intensive task, since pheromone traps, where insects are being caught, need to be visited on regular basis in order to monitor development of pest population. An innovative product which provides automated and real-time monitoring of pests reduces the need for field-scouting to minimum. In order to develop such product and to keep the whole system run...

Obtaining information about pest-insect population size is an important problem of pest monitoring and control. Usually, this problem has to be solved based on scarce spatial data about the population density. The problem of monitoring can thus be linked to a more general mathematical problem of numerical integration on a coarse grid. Numerical integration on coarse grids has rarely been consid...

In recent years, information and communication technologies have opened many opportunities to modern agriculture systems. Monitoring the fruit farm is one of the potential applications that may help improving fruit farm profitability through observing the fluctuation of the oriental fruit fly population and environmental conditions in the field. These data can be used to provide knowledge or wa...

Stored-product insects are a perennial problem in retail stores, where they damage and contaminate susceptible merchandise such as food products and animal feed. Historically, pest management in these stores has relied heavily on chemical insecticides, but environmental and health issues have dictated use of safer methods, and these require better monitoring. A monitoring procedure that employs...

Evaluation of pest abundance is an important task of integrated pest management. It has recently been shown that evaluation of pest population size from discrete sampling data can be done by using the ideas of numerical integration. Numerical integration of the pest population density function is a computational technique that readily gives us an estimate of the pest population size, where the ...
