Full text linkWith its 28,000 hectares, Trentino - South Tyrol region is the main apple-producing area in Italy and one of the most important
apple-growing district in Europe. Codling moth (Cydia pomonella) is the key pest of apple orchards and economic losses
associated with its infestation could be significant if not adequately controlled. Since the early Nineties area-wide applications of
pheromone mating disruption (MD) has been implemented in the region for the control of codling moth. At present, after 25
years of constant increase of the treated surface, mating disruption is applied on about 24,000 ha i.e. 85% of the total apple
growing area. For a complete control of the pest MD needs to be integrated with a post-blossom insecticide (methoxyfenozide or
chlorantraniliprole), generally applied when the eggs of the first generation start hatching. While the main target is still codling
moth, the multi-species dispensers are sometime applied to control leafrollers or oriental fruit moth. Once largely used, handapplied
reservoir dispensers are nowadays gradually replaced by aerosol technology that has shown comparable efficacy and
reduced application costs. Additional insecticide applications potentially required to control new invasive alien species like
Halyomorpha halys, the northward expansion of Ceratitis capitata, or the new outbreaks of apple proliferation disease vectored
by Cacopsylla picta and Cacopsylla melanoneura can jeopardize the economic sustainability of MD application and foster
research institutions and advisory services to find alternative control technique
Susceptibility of two strains of Amblyseius andersoni Chant. (Acari: phytoseiidae) to dithiocarbamate fungicides
No full textThe effect of five fungicides on adult female mortality, fecundity, egg hatch and on lan, al mortality was examined in the laboratory using a fungicide-susceptible and a fungicide-resistant strain of thepredaceous phytoseiid mite, Amblyseius andervoni Chant. The combined effect of each fungicide was compared using a coefficient of toxicity computed using the above four toxicity factors. The susceptible and resistant strains were most affected by the bidithiocarbommate fungicides mancozeb,metirmn and propineb. Ziram and dithianon had little effect on the S strain and ziram had little effect on the R strain. The toxicity of dithianon was not tested using the R strain. A resistance factor (LCsoR strain : LC~ S strain) of 6.13 for mancozeb was estimated for the R strain. Mancozeb resistance was a heritable trait and was primarily associated with the adult female
