Field tests were carried out in four European countries and diﬀerent combinations of semiochemicals were compared. gratis single dating nettsteder irland Sommeren 2017 ble det samlet 100 bladprøver fra norske jordbærfelt plantet i perioden 2015-2017 med importert plantemateriale, for å lete etter liten jordbærbladlus (Chaetosiphon fragaefolii). R., Ralle, B., Rendina, P., Richoz, P., Sigsgaard, L., Storberget, S., Trandem, N. Using the SBW aggregation pheromone and ETB sex pheromone we optimized and tested a single trap for both species. This was done by conducting laboratory studies on the virulence of two Pandora isolates (collected in the same field) on R. speed dating i glendale az The two-spotted spider mite, Tetranychus urticae, is a serious pest of numerous crops worldwide. floridana and accelerate the development of an epizootic.
A volatile from straw- berry ﬂowers, 1,4 dimethoxybenzene (DMB), increased the attractiveness of the aggregation pheromone to both sexes of A. The host-plant volatile, phenylacetaldehyde (PAA), increased the attraction of female L. rugulipennis and PAA attracted both target species to the same trap with no signiﬁcant diﬀerence in catches compared to those single-species traps. Denne bladlusarten er på grunn av sin rolle som virusvektor forbudt å introdusere og spre i Norge. Den ble heller ikke funnet i denne undersøkelsen, der til sammen 10 000 blader ble undersøkt. T., Baroffio, C., Borg-Karlson, A., Brain, P., Cross, J. A series of field experiments in crops and seminatural habitats in five European countries tested capture of the target pests and the ability to avoid captures of beneficial arthropods. padi and Myzus persicae at three temperatures (12, 15 and 18◦C). persicae is a polyphagous aphid that may be present on weeds. This is the first study quantifying the effect of P.
Baroffio, C., Sigsgaard, L., Ahrenfeldt, E., Borg-Karlson, A., Bruun, S. Combining plant volatiles and pheromones to catch two insect pests in the same trap: Examples from two berry crops. doi: 10.1016/j.cropro.20 dating området b2 Most horticultural crops are attacked by more than one insect pest. Under certain conditions, they can cause epizootic events and control pest aphid populations. urticae in the treatment with both the predator and the pathogen had declined to zero in both experiments, while in the fungus-only treatment T.
rugu- lipennis to the sex pheromone, and, in strawberry, there was some evidence that adding DMB increased catches further. In raspberry, catches in traps baited with a combination of A. A Unitrap containing a trapping agent of water and detergent and with a cross vane was more efficient at capturing both species compared to traps which incorporated glue as a trapping agent. It can be an alternative host for Pandora and hence might also affect the epidemic development of Pandora in aphids that are cereal pests. padi is more resistant to the tested Pandora isolates than M. The two Pandora isolates had different virulence in the two aphid species tested.
rubi aggregation pheromone, DMB and the commercially available lure for B. Kartlegging av liten jordbærbladlus (Chaetosiphon fragaefolii) 2017. Adding a green cross vane deterred attraction of non-pest species such as bees, but did not compromise catches of the target pests. IPM in strawberry - testing three IPM regimes in five Norwegian commercial fields (Foredrag).
