Spatial and temporal dynamics of Frankliniella occidentalis and its natural enemies in ornamental crop systems
No full textSingle and combined releases of biological control agents against canopy- and soil-dwelling stages of Frankliniella occidentalis in cyclamen
No full textBiological control agents (BCA) can be used against Frankliniella occidentalis as an alternative to conventional insecticides. Amblyseius swirskii, Neoseiulus californicus and Orius laevigatus were applied to the canopy and Macrocheles robustulus and Steinernema feltiae to the soil in single and combined releases. The combination of nematodes in the soil and predatory mites in the canopy caused a more prompt reduction of thrips in flowers
The effect of insecticides on the non-target predatory mite Kampimodromus aberrans: Laboratory studies
No full textKampimodromus
aberrans is the most important predator of herbivorous mites in South-European vineyards treated
with selective pesticides. The impact of pesticides on K. aberrans populations has been studied in field
conditions whereas few toxicological tests have been conducted in the laboratory because of difficulties
in rearing this species. In this paper, a toxicological method to assess the effects of pesticides
on K. aberrans is described and the effects of insecticides frequently used in European vineyards on
two K. aberrans strains are reported. These strains were collected from vineyards treated with organophosphates.
Insecticides characterized by different modes of action were selected for trials. Among these,
etofenprox and spinosad were classified as harmful to predatory mites. Chlorpyrifos reduced predatory
mite fecundity, and was classified as moderately harmful for both strains. The toxicity of thiamethoxam
and flufenoxuron varied with the strain (low to moderate). Indoxacarb and methoxyfenozide appeared to
be harmless or slightly harmful
Studio della dinamica spazio-temporale dei tripidi fitofagi e dei loro antagonisti naturali su colture ornamentali protette
No full textSpatial and temporal dynamics of Frankliniella occidentalis on protected ornamentals.
No full textWestern flower thrips (WFT) Frankliniella occidentalis is a worldwide problem of various
ornamentals and vegetables, especially under greenhouse. Here we present preliminary results of a
study on spatial structure of a WFT population and its evolution over time on ornamentals under
greenhouse. We used Spatial Analysis with Distances Indices (SADIE) methods to evaluate
nonrandomness of the distribution and association of the distributions observed at different time.
Spatial analysis of WFT population provided interesting information on the role of surrounding
environment on the insect population inside the greenhouse
Notes on the phenology and the biology of Tydeus caudatus Dugès (Acari, Tydeidae)
No full textKnowledge on the biology and ecology of the Tydeoidea is limited. Regarding feeding habits, tydeids appear as an unspecialized group. of the families Tydeidae and Iolinidae are frequently observed in vineyards associated with eriophyid Members mites, and feeding on pollen or fungi has also been reported. Tydeus caudatus Dugès is one of the most common tydeid species occurring in Italian vineyards. Tydeus caudatus populations can persist and increase in vineyards when eriophyid levels are low, suggesting that its diet includes non-prey food sources. In this paper, the suitability of pollen and grape downy mildew as food sources for T. caudatus has been explored. Some findings on the phenology of T. caudatus in vineyards are also reported
