Fuller rose beetle (Coleoptera: Curculionidae) ovipositional preference on Florida citrus
1990
Coats, S.A. | McCoy, C.W.
Viable Fuller rose beetle, Pantomorus cervinus (Boheman), egg masses were found on nearly 60% of 1,500 oranges, tangerines, and grapefruits (Citrus sinensis Osbeck, C. reticulata Blanco hybrid, and C. paradisi Macf., respectively) selected randomly from two mixed citrus groves in 1988 and 1989. However, of the 18,320 processed fruit checked in packinghouses, no. P. cervinus eggs were found. Calyx removal during the packing process may be the cause of this phenomenon. Two sampling methods for determining beetle density per tree in the field are reported; emergence traps and beating samples. An oviposition study, which enclosed 1-10 beetles on 8 m3 of tree volumes with Fiberglas mesh cage, revealed the location of oviposition sites, the relationship between beetle density and number of eggs laid per site, the variability of eggs deposited over time of year, and how this variability is correlated to ambient temperature fluctuations.
