AbstractPheromone traps were deployed in Borsod-Abaúj-Zemplén County (Hungary) between 1982 and 1988, in 1990 and also between 1993 and 2013. These traps attracted 8 Microlepidoptera species:Phyllonorycter blancardella, P. corylifoliella,Anarsia lineatella,Eupoecilia ambiguella,Lobesia botrana,Grapholita funebrana,G. molestaandCydia pomonella. We examined the trapping data of these species in the context of lunar phases and polarized moonlight. Catches of the European Vine Moth (Lobesia botrana) and the Codling Moth (Cydia pomonella) were higher in the First Quarter, whereas catches of Peach Twig Borer (Anarsia lineatella), Vine Moth (Eupoecilia ambiguella), Plum Fruit Moth (Grapholita funebrana) and Oriental Fruit Moth (Grapholita molesta) were larger in the Last Quarter. Catches of the other two species, the Spotted Tentiform Leafminer (Phyllonorycter blancardella) and Hawthorn Red Midget Moth (P. corylifoliella), were higher in both the First and Last Quarters. When using pheromone traps, insects do not fly to a light source, so moonlight does not modify either the catching distance or flight activity. However, at high levels of polarized moonlight, pheromone trap catches will increase, as in the case of light-trap catches. The results are comprehensible when one considers that the target species can fly both during the daytime and also at night.

Abstract The grapevine moth (Lobesia botrana) and the grape berry moth (Eupoecilia ambiguella) are the main pests in southern Slovakia vineyards. While L. botrana represents the most common species in the vineyards, E. ambiguella exists in some sites only. In this study we monitored the occurrence and dynamics of the flights of the grapevine moth and the grape berry moth in the vineyard area Dvory nad Žitavou. The size of the examined area was 60 ha in 2008 and 90 ha in 2009. On these areas, we used pheromone traps type Deltastop LB for grapevine moth and Deltastop EA for grape berry moth. To control the movement of the pests, a set of three pheromone traps for each type was used in observation points which were placed at least 50 m from each other. Monitoring was carried out regularly every second to third day. The control area was located in immediate vicinity of the area. As a threshold, we consider 20 moths for 2 days at an average of three pheromone traps. In 2008, we recorded the first, second and third generation of Lobesia botrana and only the second generation of Eupoecilia ambiguella. In 2009, we saw all three generations for both types of moths. We also examined effectiveness of the protection method of grapevine based on the mating disruption using pheromone dispensers type ISONET L plus. Just before the anticipated start of swarming we distributed 420 dispensers/ha evenly over the entire vineyard; on the edges of the treated area, the basic dose of dispensers i.e. 500 pieces/ha was left. To assess the effectiveness of the product ISONET L plus in 2008 we reached more than 70% efficiency in the border plots, inside 96%. We achieved 69% efficiency in 2009. Based on the results it is be clear that the long-term use of this method of protection has a positive impact in reducing the population of moth. It is suitable for use in an integrated and biological protective system against Lobesia botrana and Eupoecilia ambiguella.

Habitat simplification and intensive use of pesticides are main drivers of global arthropod declines and are, thus, decreasing natural pest control. Organic farming, complex landscapes, and local vineyard management practices such as implementation of flower-rich cover-crop mixtures may be a promising approach to enhance predator abundance and, therefore, natural pest control. We examined the effect of organic versus integrated management, cover-crop diversity in the vineyard inter-rows, and landscape composition on the natural pest control of Lobesia botrana eggs and pupae. Predation of L. botrana pupae was reduced by organic farming and species-poor cover-crops by about 10%. Predation rates of L. botrana eggs did not differ significantly in any of the studied management options. Dominant predators were earwigs (Forficulidae), bush crickets (Tettigoniidae), and ants (Formicidae). Negative effects of organic viticulture are most likely related to the negative nontarget effects on arthropods related to the frequent sulfur and copper applications in combination with the avoidance of strongly damaging insecticides by integrated winegrowers. While a 10% difference in predation rates on a single pest stage is unlikely to have strong practical implications, our results show that the assumed effectiveness of environmentally friendly agriculture needs to be evaluated for specific crops and regions.

This paper reviews the existing predictive models concerning insects and mites harmful to grapevine. A brief conceptual description is given on the definition of a model and about different types of models: deterministic vs. stochastics, continuous vs. discrete, analytical vs. computer-based, and descriptive vs. data-driven. The main biological aspects of grapevine pests covered by different types of models are phenology, population growth and dynamics, species distribution, and invasion risk. A particular emphasis is put on forecasting epidemics of plant disease agents transmitted by insects with sucking-piercing mouthparts. The most investigated species or groups are the glassy-winged sharpshooter Homalodisca vitripennis (Germar) and other vectors of Xylella fastidiosa subsp. fastidiosa, a bacterium agent of Pierce’s disease; the European grape berry moth, Lobesia botrana (Denis and Schiffermuller); and the leafhopper Scaphoideus titanus Ball, the main vector of phytoplasmas agents of Flavescence dorée. Finally, the present and future of decision-support systems (DSS) in viticulture is discussed.

AbstractThe grape berry moth Eupoecilia ambiguella (Lepidoptera: Tortricidae) is causing significant damage to grape berries, however, little is known on population genetics of this lepidopteran pest insect, hindered so far by the lack of suitable molecular markers. Here we report on the development of ten microsatellite markers of which six were used to characterise 21 E. ambiguella populations obtained from two viticultural regions in Germany and Italy. Moths were sampled during two subsequent generations (flights) in the same vineyard as well as in vineyards surrounded by different landscape types. German and Italian populations were genetically differentiated and a significant isolation by distance was evident. No significant divergence was observed among the populations from first or second flight moths, however, inbreeding was higher in first than in second flight populations. Moreover, inbreeding was influenced by habitat composition and complexity of landscape around vineyards, being positively associated with the percentage of area covered by grapevine. Population genetics of E. ambiguella could thus be affected by the presence of alternative host plants in viticultural landscapes, which is important in the light of both insecticide resistance management and sustainable pest management.

AbstractFor insect herbivores, the quality of the larval host plant is a key determinant of fitness. Therefore, insect populations are supposed to be positively correlated with the nutritional quality of their host plant. This study aimed to determine if and how different varieties of grapes (including the wild grape Lambrusque) affect both larval and adult performance of the polyphagous European grapevine moth Lobesia botrana (Denis & Schiffermüller). Significant differences were found in larval development time, but not in pupal mass, adult emergence rate, or sex ratio. Although the fecundity of females is not different among varieties, females fed on some varieties produced eggs of different sizes which are correlated to their fertility. Thus, females adapt resource allocation to eggs depending on their diet as larvae. Using a fitness index, the average reproductive output was found to be highest for females reared on cv. Chardonnay. Females reared on wild grape produced a fitness index identical to the cultivated grapes. However, Lambrusque and Gewurztraminer separate themselves from the cultivated varieties according to our discriminant analyses. It is emphasized, through this study, that cultivars fed on by larvae should be considered in the population dynamics of L. botrana and that egg number is insufficient to determine host plant quality.
