Sažetak
A number of aphid species have been recorded as watermelon crops feeders. Mulching is a common practice in field grown watermelon crops in Croatia. The most often used cover is the black polyethylene (PE) mulch. Type and color of mulch material may influence aphid populations in the crops. The aim of this study was to compare the effect of PE black mulch with bare soil and hay cover against aphid number. In order to create management strategy in watermelon, flight dynamics of aphid population was recorded. In 2008, the field experiment was set up as a randomized block design in three replications at Pula in Mediterranean region of Croatia. Winged aphids were collected weekly using yellow water metal traps. There were six sampling dates starting from 19 May until mulch was covered by plant canopy. We found significant difference in aphid number among the sampling dates as a result of their population dynamics on watermelon. The catches of two assessments in the second half of May were more numerous than during assessments in June. The flight maximum was recorded on 26 May and the population density significantly decreased from June 9. There was not much effect of mulch on aphid number. However, at the peak of aphid population hay cover attracted 13% (26 May) and 18% (2 June) more aphids compared to bare soil.
