Vaskemetoden med alkohol minder meget om vaskemetoden med sæbe. Her beskriver vi det vaskesystem der hedder EasyCheck.
EasyCheck er en nem og hurtig metode i bigården. Der findes flere forskellige typer af dåser på markedet. Man kan også nemt selv lave en dåse med net. Man kan bruge almindelig alkohol (husholdningssprit – sørg for udluftning). Nogle bruger sprinklervæske, som nok indeholder for lidt alkohol til en god og sikker test.
EasyCheck er delt op i en dåse og en si. Der fyldes alkohol i dåsen, således at mængden lige når op til siens kant. Bemærk at der i sien er to streger. En nedre, som angiver en prøvestørrelse på 200 bier, og en øvre streg, som angiver 300 bier.
Man tager en tavle, med påsiddende bier, der sidder lige uden for yngellejet og bruger sien til at køre forsigtigt hen over bierne, således at de ruller baglæns ned i dåsen (se også afsnittet ”Udtagning af biprøve” på side 14). Der fyldes med bier indtil den valgte streg. Dåsen lukkes og vendes et par gange, således at bierne dør i væsken. Herefter efterfyldes med alkohol halvvejs op i dåsen.
Herefter drejer man dåsen i ca. 1 minut. Det er fristende at ryste dåsen kraftigt, men det gør bare at
man blander miderne mere op i biprøven, i stedet for at de langsomt daler ned på bunden. Så rolige svingninger fungerer bedst.
Lad dåsen stå lidt og herefter kan man tælle antallet af mider på bunden af dåsen. Ved 300 bier skal man
dividere antallet af mider med 3 og så har man antal mider per 100 bier – for en prøve med 200 bier skal
antallet af mider divideres med 2 for at give antal mider per 100 bier.
Væsken kan genbruges ved at hælde den over i en anden bøtte og fjerne bundfaldet med mider, eller ved
at hælde den gennem en lille tesi. En del erhvervsbiavlere anvender denne metode i praksis.
Bier fyldes i dåsen.
Alkohol fyldes på.
Bierne kan tælles på bunden af dåsen eller ved at hælde væsken gennem en fintmasket si, f.eks. en tesi.
