“…Furthermore, aldehydes were the chemical group that contributed most to the differentiation of the apple blends according to their attraction to the moths. The codling moth also is an oligophagous species whose larvae feed primarily on Rosaceae plants, with apples and pears being its main hosts (Wearing et al 2001;Witzgall et al 2008). Thus, aldehydes also might play a role in the attraction of the codling moth, and possibly of other oligophagous fruit moths of the same tribe Grapholitini, to Rosacean hosts.…”

Insect herbivores that have more than one generation per year and reproduce on different host plants are confronted with substantial seasonal variation in the volatile blends emitted by their hosts. One way to deal with such variation is to respond to a specific set of compounds common to all host plants. The oriental fruit moth Cydia (=Grapholita) molesta is a highly damaging invasive pest. The stone fruit peach (Prunus persica) is its primary host, whereas pome fruits such as pear (Pyrus communis) are considered secondary hosts. In some parts of their geographic range, moth populations switch from stone to pome fruit orchards during the growing season. Here, we tested whether this temporal switch is facilitated by female responses to plant volatiles. We collected volatiles from peach and pear trees in situ and characterized their seasonal dynamics by gas chromatography-mass spectrometry. We also assessed the effects of the natural volatile blends released by the two plant species on female attraction by using Y-tube olfactometry. Finally, we related variations in volatile emissions to female olfactory responses. Our results indicate that the seasonal host switch from peach to pear is facilitated by the changing olfactory effect of the natural volatile blends being emitted. Peach volatiles were only attractive early and mid season, whereas pear volatiles were attractive from mid to late season. Blends from the various attractive stages shared a common set of five aldehydes, which are suggested to play an essential role in female attraction to host plants. Particular attention should be given to these aldehydes when designing candidate attractants for oriental fruit moth females.

“…It has demonstrated an ability to colonize apple and pear trees wherever the climate is suitable for their commercial production. It is evident that present distribution of codling moth is related to climatic factors as well as to food conditions (WEARING, et al, 2001).…”

SVOBODOVÁ EVA, TRNKA MIROSLAV, DUBROVSKÝ MARTIN, SEMERÁDOVÁ DANIELA, EITZINGER JOSEF, ŽALUD ZDENĚK, ŠTĚPÁNEK PETR: Pest occurrence model in current climatevalidation study for European domain. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 1, pp. 205-214 The present study yields detail validation of the pest occurrence models under current climate in wide European domain. Study organisms involve Cydia pomonella, Lobesia botrana, Ostrinia nubilalis, Leptinotarsa decemlineata, Oulema melanopus, Rhopalosiphum padi, and Sitobion avenae. Method used in this study belongs to the category climate matching (CLIMEX model) allowing the estimation of areas climatically favourable for species persistence based on the climatic parameters characterising the species development. In the process of model validation parameters were iteratively tested and altered to truly describe the pest presence. The modelled pests presence was verifi ed by comparison of the observed pests occurrence with the number of generations in given modelled area. The notable component of the model parameterization was the sensitivity analyses testing the reaction of species development on changing meteorological items. Parameterization of the factors causing distribution patterns of study species was successful and modelled potential distributions of species correspond well to known core distribution areas for all of these species. This validation study is intended as an initial for forthcoming studies focused on the estimation of geographical shi s of selected pests in the conditions of climate change within the Europe.climate change, climate matching, pests, endangered areas, northern range, CLIMEX Productivity of crops grown for human consumption is at risk due to the incidence of pests, especially weeds, pathogens and animal pests, for instance without crop protection almost 75 % of attainable potato production would be lost to pests (OERKE, 2006). Pest life cycles are aff ected by various factors, among which climate conditions are the most signifi cant. Climate can limit the distribution of a species directly by infl uencing survival and fecundity or indirectly through its eff ects on interacting species, including food sources, natural enemies and competitors (GASTON, 2003). Under current climate conditions, insect species diversity per area tends to decrease with increasing latitude. A similar trend is usually seen with increasing altitude (GASTON, WILLIAMS, 1996).The present validation study represents the base material for forthcoming studies estimating the occurrence area of selected pests in the conditions of climate change. Projected studies will focused on the geographical shi of species northern range and determination of areas the most endangered by newly species establishment. Warmer conditions of climate change may be expected to promote pole ward extension of the ranges of species that are currently limited by low temperature. Changes in climate may result in alterations in the geogra...

“…For example, sweet cherry is a very poor host for codling moth (45, 46, 49, 50), and some believe it is a nonhost (135). In sweet cherries from California and the U.S. Pacific Northwest in 1997, four suspected codling moth larvae were found in more than 218 million inspected cherries exported to Japan, an infestation rate of 1.8 × 10 −8 , and in 1998 and 1999, no codling moth larvae were found in more than 423 million inspected cherries (34).…”

Key Words quarantine pests, phytosanitary measures, probit 9 alternatives, generic treatments, systems approach ■ Abstract With world trade in agricultural commodities increasing, the introduction of exotic insects into new areas where they become pests will increase. The development and application of quarantine treatments or other mitigation approaches to prevent pest introduction in traded commodities raise many research and regulatory issues. The probit 9 standard for quarantine treatment efficacy has given way to riskbased alternatives. Varietal testing may have merit for some treatments or commodities but not for others. Development of generic treatments to control broad groups of insects or insects in all commodities can expedite new trade in agricultural products. Area-wide pest management programs lower pest levels before harvest and improve the quarantine security provided by any postharvest treatments. Systems approaches capitalize on cumulative pest mortality from multiple control components to achieve quarantine security in an exported commodity. Certain quarantine treatment technologies such as irradiation are not universally accepted, which is slowing their adoption. Standardized phytosanitary measures and research protocols are needed to improve the flow of information when countries propose to trade in a regulated commodity.
