The spruce seed moth, Cydia strobilella L., is a serious pest on cones of spruce (Picea spp.) in the Holarctic region. Previous studies from different parts of its area of distribution have reported…
Effects of repeated slash removal in thinned stands on soil chemistry and understorey vegetation
The effects of whole-tree thinning on soil chemistry and understorey vegetation were generally minor and variable and across all sites the concentrations of Ca and Mg were significantly lower when slash was removed.
Assessment of genetic and pheromonal diversity of the Cydia strobilella species complex (Lepidoptera: Tortricidae)
This study demonstrates the great potential of using pheromone trapping as a tool for identification and delimitation of taxa within cryptic species complexes.
Assessment of cone-damaging insects in a Swedish spruce seed orchard and the efficacy of large-scale application of Bacillus thuringiensis variety aizawai x kurstaki against lepidopterans.
Investigation of the efficacy of large-scale application of the biological insecticide Bacillus thuringiensis variety aizawai x kurstaki in a Swedish spruce seed orchard for controlling damage caused by four lepidopteran species revealed that E. abietaria occurred in similar numbers to D. abetella and has probably been overlooked as a potentially serious pest in spruce Seed orchards in Sweden.
Systemic Insecticide and Gibberellin Reduced Cone Damage and Increased Flowering in a Spruce Seed Orchard
The results suggest that it may be possible to reduce damage from certain insect species, and to increase flowering by injecting abamectin and GA4/7 in the year before a cone crop.
Assessment of Cone-Damaging Insects in a Swedish Spruce Seed Orchard and the Efficacy of Large-Scale Application of Bacillus thuringiensis variety aizawai × kurstaki Against Lepidopterans
In a 2-yr study, we investigated the efÞcacy of large-scale application of the biological insecticide Bacillus thuringiensis variety aizawai kurstaki (Btk) in a Swedish spruce, Picea abies L.…
Sex pheromone of the cloaked pug moth, Eupithecia abietaria (Lepidoptera: Geometridae), a pest of spruce cones
With sex pheromones recently identified for two other moths that are major pests on spruce cones, the spruce seed moth, Cydia strobilella L., and theSpruce coneworm, Dioryctria abietella Denis & Schiffermüller, phersomone‐based monitoring can now be achieved for the whole guild of cone‐feeding moths in European spruce Seed orchards.
(3Z,6Z,9Z,12Z,15Z)‐pentacosapentaene and (9Z,11E)‐tetradecadienyl acetate: sex pheromone of the spruce coneworm Dioryctria abietella (Lepidoptera: Pyralidae)
It is shown that a second female‐produced compound, the polyunsaturated long‐chain hydrocarbon (3Z,6Z,9Z,12Z,15Z)‐pentacosapentaene (C25 pentaene), is a strong synergist to 9Z,11E‐14:OAc, and that both compounds are needed for significant attraction of males.
Challenges of pheromone-based mating disruption of Cydia strobilella and Dioryctria abietella in spruce seed orchards
The results show that mating disruption has potential to reduce cone damage in spruce seed orchards caused by C. strobilella and D. abietella, but optimisation of the technique is required to achieve consistent and efficient population suppression of these pests.
