A grapevine leafminer Antispila oinophylla van Nieukerken & Wagner, sp. n., is described both from eastern North America (type locality: Georgia) and as a new important invader in Italian vineyards (Trentino Veneto Region) since 2006. The species closely related to, previously confused with A. ampelopsifoliella Chambers, 1874, feeding on Virginia creeper Parthenocissus quinquefolia (L.) Planchon., are placed an informal group. Wing pattern, genitalia, DNA barcode data all confirm the...

Abstract Laboratory trials were carried out in order to test the effects of 29 pesticides on predatory bug, Orius laevigatus. To evaluate residual contact activity, newly moulted fourth instar nymphs O. laevigatus placed treated Petri dishes and their mortality was checked after 7 days. The fecundity surviving females tested for 14 Young adults fed with eggs Ephestia kuehniella, (above-mentioned) pesticides, assess effect by ingestion. Adult mortality, female egg hatching recorded....

Abstract: A mating disruption approach using high densities of pheromone dispensers, has recently been proposed for controlling codling moth, Cydia pomonella (L.) (Lep., Tortricidae). Ecodian® CP made low‐cost biodegradable material and easy to apply, were formulated with 10 mg codlemone placed at a rate 1400–2000 dispensers/ha. Seasonal dispenser performance was evaluated different methods. The release new Ecodian measured directly by solid‐phase micro‐extraction (SPME), significantly...

The codling moth, Cydia pomonella L. (Lepidoptera, Tortricidae), is a major pest of apple, pear and walnut orchards worldwide. This often controlled using the biologically friendly control method known as pheromone-based mating disruption. Mating disruption likely exerts selection on sexual communication system male female moths will persist in their attempt to meet mate. Surprisingly little intraspecific variation this species. We started an investigation determine level individual sex...

In the current study, incidence of 'Candidatus Phytoplasma mali' in an experimental apple orchard northeast Italy, addition to abundance and phytoplasma infectivity Cacopsylla melanoneura (Förster) (Hemiptera: Psyllidae) was determined role this psyllid as a vector 'Ca. P. region reviewed. Insect samples collected by beating method indicated high C. (up 7.92 specimens/branch); however, picta not observed. Molecular analyses revealed presence 6.25% overwintered psyllids. This infection rate...

Abstract Ceratitis capitata (Wiedemann), the Mediterranean fruit fly, is one of key pest species affecting deciduous orchards along coasts. Because global warming, C. gradually spreading north and becoming a major apples. Determining susceptibility main apple varieties grown in region will serve as cornerstone to management this pest. In study, we show results field laboratory no‐choice test conducted determine Medfly preferences on different cultivars. The seven apples (Gala, Red Delicious,...

The mosaic leafhopper, Orientus ishidae (Matsumura), is an Asian species widespread in Europe that can cause leaf damage wild trees and transmit disease phytoplasmas to grapevines. Following O. outbreak reported 2019 apple orchard northern Italy, the biology caused by this apples were investigated during 2020 2021. Our studies included observations on life cycle, symptoms associated its trophic activity, capability acquire "Candidatus Phytoplasma mali," a causal agent of Apple Proliferation...

Abstract BACKGROUND: Cacopsylla melanoneura (Förster) is a vector of Candidatus Phytoplasma mali , the causal agent one most serious diseases in European apple orchards, proliferation (AP). The aim this study was to evaluate toxicity five insecticides from different chemical groups (carbamates, chitin inhibitors, insect growth regulators, organophosphates and pyrethroids) towards overwintered adults young stages C. under semi‐field conditions. RESULTS: organophosphate chlorpyrifos pyrethroid...

Mating disruption with a high density of sex pheromone dispensers is new strategy recently developed for the control moth Lobesia botrana (Denis & Schiffermüller) (Lepidoptera: Tortricidae). Ecodian LB dispensers, made low-cost biodegradable material, were formulated 10 mg (E,Z) -7,9-dodecadienyl acetate and placed at rate 1,600 per ha. Seasonal dispenser performances studied using different methods. The female attractiveness efficacy method evaluated in field. release rates field-aged...

Field trials were carried out in order to evaluate the seasonal abundance and impact on yields of Apple Rust Mite (ARM) Aculus schlechtendali (Acari: Eriophyidae) an experimental fruit orchard located northern Italy (Trentino region). The effect ARM yield market quality parameters assessed Golden Delicious apple fruits. Fruit size, weight, round colour hue, presence russet as well inside quality, i.e. soluble solids, acidity Perlim index, evaluated over two seasons considering three...

Background: Amblyseius andersoni is a common predatory mite occurring in fruit orchards located Europe and North America. Its role preventing spider outbreaks widely recognized, particular when selective pesticides are used. The compatibility between plant protection products mites crucial to preserve their activity. There need investigate the effects of on beneficials using multiple approaches. Objectives: Field laboratory experiments were conducted evaluate number insecticides A....

Two heliozelid species, Antispila oinophylla van Nieukerken & Wagner and Holocacista rivillei (Stainton) severely infest Italian grapevines. The volatile pheromones from calling females were collected by solid phase micro extraction (SPME) analyzed gas chromatography with electroantennographic detection (GC-EAD). compounds A. eliciting electrophysiological activity the conspecific male antenna identified as (Z)-5-tetradecenal (Z)-7-tetradecenal coupled chromatography/mass spectrometry...

Generalist predatory mites belonging to the Phytoseiidae play a major role in keeping phytophagous below economic threshold levels European apple orchards and vineyards. Apart from their primary prey, these phytoseiids can exploit range of other foods, among which pollen plant pathogenic fungi are very important. The ability generalist feed on alternative foods is importance for persistence perennial crops. Pesticides exert dramatic effects mite communities, be more severe predators than...
