| Description
| - %22Traps are tools frequently used for monitoring and control of pests. Therefore it is importantto study prerequisites oftheir use. The instant active area oftrap (the instantly available area of a trapthat is able to capture a pest) determines trap efficacy. However, the measurement of instant activetrap area is difficult. Therefore, we developed a technique of computer image analysis of digital photography for evaluation of instant active trap area, occupancy (area of insect bodies captured on trap) and contamination (area of filth left by pests on traps, such as wing-scales or faeces) of traps. We found that the Mediterranean flour moth, Ephestia kuehniella decreased the capacity of the sticky surface more than its parasitoid Venturia canescens because of contamination by wing scales. The sticky trap area covered by wing scales was nearly as large as the area occupied by moth bodies. The results indicate that moths are heavy contaminators while parasitoids don't contaminate sticky traps.

- Lapače jsou hojně používaným prostředkem pro monitorování výskytu škůdců. Znalost jejich účinnosti je ne-zbytná pro jejich efektivní používání a interpretaci výsledků. Okamžitá aktivní plocha lapače (tj. momentálně dostupná plocha schopná zachycovat monitorovaného škůdce) je určující pro účinnost lapačů. Zjišťování velikosti obsazenosti (tj. plocha obsazená těly škůdců) a kontaminace (tj. plocha kontaminovaná nečistotami, např. výkaly, šupinkami křídel motýlů) navrhujeme využití metody obrazové analýzy. Bylo zjištěno, že zavíječ moučný (Ephestia kuehniella) snižuje kvůli kontaminací šupinkami křídel mnohem výrazněji plochu lapače než jeho parazitoid Venturia canescens. Plocha znehodnocená/kontaminovaná přítomností šupinek byla téměř shodná s plochou, kterou pokrývala těla motýlů.. Výsledky naznačují, že skladištní zavíječí kontaminují velmi silně feromonové lepové lapače, zatímco parazitoidi nekontaminují tento typ lapačů vůbec. (cs)
