Other claims from this paper (11)
- Intervention effect Insecticidal drift from surrounding treated areas so severely upset biological control of Icerya purchasi on desert citrus that chemical control became necessary.
- Intervention effect Malathion drift is worse than parathion drift because it produces no balancing destruction of the host.
- Association Interference with vedalia destruction is most often caused by drift of malathion, parathion, or DDT applied by airplane in early spring.
- Intervention effect Restricting insecticidal drift largely eliminated the problem of Icerya on desert citrus.
- Intervention effect Colonization by vedalia controlled Icerya outbreaks when vedalia could be obtained.
- Observation Propagation of vedalia was found to be impractical.
- Observation Field-collected vedalia pupae or adults may be stored for long periods.
- Observation Periodic colonization of Cryptochaetum iceryae was tested but considered impractical.
- Observation Other natural enemies introduced against Icerya were not successfully established.
- Observation Icerya is normally controlled biologically before June on desert citrus.
- Association Cold temperatures restrict vedalia activity from November to March in the desert.
