Interaction between Uroplata girardi (Coleoptera: Chrysomelidae) and Ophiomyia camarae (Diptera: Agromyzidae) on a shared host Lantana camara (Verbenaceae). Oxford: Blackwell Science.Īpril, V., Robertson, M. Alford (Ed.), Biocontrol of oilseed rape pests (pp. These results demonstrate the need for studies on biotic interactions among biocontrol agents, prior to release of the biocontrol agents of weeds.Īlford, D. Results of such interactions are often variable and less predictable, especially under field conditions. But FR + NB and PS + NB treated plants were far less damaged compared to when these agents were applied separately. FO + NB and FO + OT treated plants showed enhanced damage percentage of about 90%, after 120 h. Biocontrol agents applied in combination had cumulative impact on the target weed. Observations were made on percentage damage caused by these agents to water hyacinth. roseum (FR), Paradendryphiella salina (PS) and two host-specific arthropods Orthogalumna terebrantis (OT) and Neochetina bruchi (NB) were applied on water hyacinth plants singly and in various combinations (OT, NB, FO, FO + OT, FO + NB, FR, FR + OT, FR + NB, PS, PS + OT, PS + NB). In order to understand such possibilities, three potential fungi, Fusarium oxysporum (FO), F.
Therefore studies on their interaction become even more important. Due to their overlapping niches, interspecific interactions among the biocontrol agents is high and there is a paucity of information on possible positive or negative impact they may have on each other hence affecting the biocontrol. Several biocontrol agents are being introduced for the control of invasive species like the aquatic macrophyte, waterhyacinth, Eichhornia crassipes, in the hope of improving the eco-friendly natural control mechanism. Interspecific interactions play an important role in ecosystem functioning.
