dct:abstract

The biology of leaf mining Agromyzidae living on Lonicera periclymenum L., Lonicera xylosteum L. and Symphoricarpos rivularis Suksdorf was studied in the surroundings of Kiel (Schleswig-Holstein, FRG [West Germany]). An identification key is given for the 5 Agromyzid species occurring in the investigation area, Paraphytomyza cornigera Griffiths, P. bendeliana (Hering), P. luteoscutellata (De Meij.), Phytomyza periclymeni De Meij. and P. lonicerae (Rob.-Desv.). Observations were made on the phenology and feeding behaviour of these species, their abundances, host and biotope specificity, as well as temporal and spatial segregation. Ecological segregation is particularly discussed in relation to host-plant chemistry. In P. luteoscutellata, occurring in high densities, intraspecific competition was observed. When 4 or more larvae mined the same leaf, a reduction of feeding time and premature pupation was obvious. Further, density dependent parasitism was found to regulate larval mortality in P. luteoscutella. 13 parasitic Hymenoptera species of the families Braconidae and Eulophide were reared from the 5 Agromyzid hosts investigated.
