Sustainable Integrated Management of Whiteflies
as Pests and Vectors of Plant Viruses in Asia |
Subproject Description ::
|
The overall project aims are to identify
components for inclusion in a sustainable IPM strategy for control
of whitefly-transmitted geminiviruses and whiteflies on tomato. Evaluation
of geminivirus-resistant tomato lines and hybrids for resistance to
Vietnamese geminiviruses is a major project activity; development
of probes specific for major Vietnamese tomato geminiviruses and geminivirus
identification will be conducted in conjunction with resistance trials
to determine the relationships between specific viruses and resistance.
Petroleum spray oils (PSO), which are known to repel whiteflies and
reduce transmission efficiency, will be tested for their effectiveness
in reducing/delaying virus infection. PSO may help improve the durability
of resistance by reducing whitefly probing and lowering the chances
of infecting resistant plants with resistance-breaking strains. Project
objectives are:
- To evaluate existing AVRDC tomato hybrids and inbred lines and
other sources for geminivirus resistance and important horticultural
characters such as yield and fruit quality
- To determine if one or more tomato entries are suitable for
on-farm testing and possible release
- To develop probes specific for major geminivirus strains in
Vietnam and to correlate virus diversity and resistance
- To evaluate the efficacy of PSO in delaying/reducing infection
due to geminiviruses and other diseases
This project will continue the Asian subproject work within the Tropical
Whitefly IPM Project coordinated by CIAT. |
