Title

Effect of Flower Thrips on Onion Seed Plants and a Study of Their Control

Elmer C. Carlson Journal of Economic Entomology 1964. doi:10.1093/jee/57.5.735

Other claims from this paper (17)

Observation Flower thrips feeding injures flower filaments and causes premature pollen loss and reduced pollination and seed set.
Observation About 10 thrips per flower or floret were needed for meaningful injury.
Observation An estimated 9,000 to 10,000 thrips per seed head would be needed for economic injury and seed loss.
Observation Observed infestations reached 1900, 2400 and 3600 thrips per head.
Observation These thrips densities did not reduce onion seed set, yield, size or viability.
Intervention effect Thrips increased pollination and seed set over controls in every experiment.
Intervention effect Adding pollinators increased seed production and viability relative to thrips alone.
Observation Fly pollinators and two heads per replicate cage were needed for adequate seed set.
Observation Across three years, thrips density never caused economic onion seed loss.
Intervention effect Two or three parathion applications satisfactorily controlled thrips.
Intervention effect Two or three diazinon applications satisfactorily controlled thrips.
Intervention effect Parathion appeared to increase seed viability somewhat.
Intervention effect Parathion during bloom reduced bee and fly pollinators for about three days.
Intervention effect One prebloom dimethoate application gave outstanding thrips control.
Intervention effect The single prebloom dimethoate application did not reduce pollinators.
Intervention effect An additional bloom dimethoate application reduced pollinators for up to ten days.
Intervention effect The single dimethoate application increased seed set and yield.
