Host preference of Thrips hawaiiensis for different ornamental plants

Abstract Thrips hawaiiensis is a common thrips pest that damages the flowers of various plants. The differing population sizes T. among host plants suggest its preference and performance vary In this study, fitness for different was assessed through field investigation. behavioral responses to color volatiles eliciting apparent levels their development survival on were also studied. Adults larvae found in 21 species, which classified into four species. showed significantly visual olfactory tested (each representing one levels), with rankings preferences Dianthus caryophyllus > Tulipa gesneriana Hydrangea macrophylla Rosa rugosa , H. ≥ D. R. . Plant species had significant influences developmental times from egg adult 9.58 d, 9.92 10.35 d 10.75 respectively, corresponding rates 76.33%, 71.33%, 64.00% 59.00%. summary, study shows consistent flower tested. Further, plant are correlated rate survivorship Our adds understanding mechanism selection by provides basic information underpin management horticultural
