Škodlivost obalečů na ovocných dřevinách ve vybraných sadech na jižní Moravě
Fröhlich, Pavel
During the 2018 season, five species of leaf rollers, which are harmful to fruit trees, were monitored (Cydia pomonella, C. funebrana, C. molesta, Enarmonia formosana and Pandemis heparana). The monitoring was carried out using pheromone traps in fruit orchards in south Moravia (Lednice, Starý Lískovec, Nosislav and Velké Bílovice) with varying wood preservation intensity. C. molesta reached the highest abundance, on average 241 individuals were caught in one pheromone trap, it was observed at all three study plots, in Lednice these species reached the highest abundance with 235 individuals. First imago was caught on the 27th of April, last imago on the 16th of September. One non-target species (Epiblema scutulana) was detected in this pheromone. C. funebrana was the second most abundant species, which was detected at both study plots,on average 148 individuals of C. funebrana were detected in one trap, the highest abundance was found in Lednice (224). First imago was detected on the 7th of May, last imago on the 26th of August. Five non-target species were caught in this pheromone, Gypsonoma sociana, G. nitidulana, G. aceriana, Eucosma fervidana and E. lacteana. Enarmonia formosana reached high abundance, caught at both study plots, 140 individuals were caught on average in one pheromone trap, the highest abundance was in Starý Lískovec with 199 of pieces. Cnephasia stephensiana, in particular, was caught as nontarget species, rarely Eucosma cumulana. Cydia pomonella was found at all three study areas, on average there were 84 individuals in the trap, 150 individuals in Starý Lískovec. First imago was caught on the 26th of April. There were no non-target moth species found in this pheromone trap. Pandemis heparana was registered at two study plots, 15 individuals were caught on average in one trap, the highest abundance was in Starý Lískovec with 19 individuals. P. heparana was not detected in Nosislav. First imago was caught on the 13th of May and the last on the 16th of September. Non-target species Noctua fimbriata and N. interjecta were caught in this pheromone.
