Observationerna av \u00e4rtvecklarf\u00f6rekomsten med hj\u00e4lp av feromonf\u00e4llor forts\u00e4tter p\u00e5 S\u00e4llskapets omr\u00e5de.<\/strong><\/p>\n\n\n\n

Vi har under vecka 24, den 16-17.6., igen satt ut feromonf\u00e4llor i \u00e4rtf\u00e4lt f\u00f6r att kunna f\u00f6lja med f\u00f6rekomsten av vuxna, flygande \u00e4rtvecklare.<\/p>\n\n\n\n

I dag, den 28.6., har en \u00f6kad aktivitet kunnat m\u00e4rkas p\u00e5 observations\u00e4rtf\u00e4lten b\u00e5de i Ing\u00e5 i v\u00e4stra Nyland och i Liljendal i \u00f6stra Nyland.<\/strong> Vid avl\u00e4sningen i v\u00e4stra Nyland<\/strong> i dag fanns det 5 st respektive 3 st \u00e4rtvecklare i de tv\u00e5 f\u00e4llorna. \u00c4rterna i Ing\u00e5 \u00e4r av sorten Rokka och de \u00e4r s\u00e5dda den 14.5.<\/p>\n\n\n\n

I \u00e4rtvecklarf\u00e4llor utsatta i Karis<\/strong> var det ocks\u00e5 action eftersom antalet \u00e4rtvecklare d\u00e4r uppgick till ca 30 st per f\u00e4lla sedan i torsdags!<\/strong><\/p>\n\n\n\n

I \u00f6stra Nyland<\/strong> fanns det 11 st<\/strong> \u00e4rtvecklare i den ena f\u00e4llan och 4 st i den andra. \u00c4rterna \u00e4r av sorten Ingrid och de \u00e4r s\u00e5dda den 14.5.<\/p>\n\n\n\n

Gr\u00e4nsen f\u00f6r hotande m\u00e4ngd \u00e4r tio \u00e4rtvecklare per f\u00e4lla tv\u00e5 observationsg\u00e5nger i rad. Bek\u00e4mpningstiden infaller, beroende p\u00e5 r\u00e5dande temperatur, efter 8 \u2013 12 dygn efter den andra \u00f6ver tio st \u00f6verstigande observationen. Eventuell bek\u00e4mpning med Pyretrioder b\u00f6r i allm\u00e4nhet ske i slutet av blomningen n\u00e4r larverna f\u00f6rflyttar sig mot de spirande baljorna. <\/strong><\/p>\n\n\n\n

N\u00e4sta g\u00e5ng g\u00f6rs observationerna p\u00e5 torsdag denna vecka och nu \u00e4r det intressant att f\u00f6lja med hur l\u00e4get utvecklar sig, – \u00f6verskrids gr\u00e4nserna fortfarande?! <\/strong><\/p>\n\n\n\n

Lokalt f\u00f6rekommer det nu i \u00f6kande grad \u00e4rtbladlus<\/strong> i best\u00e5nden. \u00c4rtbladlusen \u00e4r ca 2-3 mm l\u00e5ng och svagt ljusgr\u00f6n. Gr\u00e4nsen f\u00f6r bek\u00e4mpning \u00e4r 5 st per skott men de g\u00f6mmer sig inne i toppskottets bladveck och f\u00f6r att kunna r\u00e4kna dem b\u00f6r man sl\u00e5 det avrivna toppskottet mot en utbredd handflata. Sedan senast har det p\u00e5 en del h\u00e5ll f\u00f6tts till nya l\u00f6ss som \u00e4r sm\u00e5 och som g\u00f6mmer sig inne i bladveck s\u00e5 det g\u00e4ller att f\u00f6rsiktigt \u00f6ppna upp bladen i toppen av \u00e4rtplantan f\u00f6r att hitta dessa. Bek\u00e4mpning sker med Pyretroider.<\/p>\n\n\n\n
