The first Australian record of the lily thrips, Liothrips vaneeckei Priesner, is reported from a bulb farm in Warragul South, Victoria. It is an occasional pest of Lilium bulbs, both in the field and in storage, particularly in the USA and several European countries, and is also infrequently found in considerable numbers on the corms of orchids. 相似文献

Periodic and augmentative releases of natural enemies are often required to enhance biological control and integrated pest
management programs. One requirement for these programs to be practical is that natural enemies can be easily and economically
mass-reared. This study assessed the effects of dieton the quality of the F3 and F4laboratory-reared generations of the predatory thrips,Aleurodothrips fasciapennis. Diets were eggs and crawlers of the diaspidid scale Chrysomphalusaonidum and eggs of the pyralid moth Corcyracephalonica. It was found that both the F3 and F4 generations were not viable when reared on the eggs and crawlers of C. aonidum due to very low fecundity and, in the F4 generation, increased larval mortality. In contrast, thrips reared on the eggs of C. cephalonica were viable in both generations but an increase in larval mortality from the F3 to the F4 generation did result in are duction in viability. These results are discussed in terms of genetic, environmental and behavioural
factors that may have influenced the quality of the thrips. It is concluded that genetic factors(inbreeding suppression, genetic
drift or selection),the behaviour of scale crawlers and the predatory behaviour of thrips were probably of little value in
explaining the results. The most likely explanation was that the diet supplied to thrips was of in adequatenutritional quality.
It was not possible to distinguish whether this was due to low intrinsic quality of the prey or an indirect effect of experimental
conditions on prey quality.

Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae) (hereafter Schinus), is one of the worst invasive species in Florida and Hawaii. The thrips Pseudophilothrips ichini Hood (Thysanoptera: Phlaeothripidae) is being considered as a potential biological control agent of Schinus. Two populations of this thrips were collected in the weed's native range; one from central-east Brazil (Ouro Preto thrips) and a second from north-east Brazil (Salvador thrips). Temperature requirements, adult fecundity and impact on different plant haplotypes by P. ichini were examined in the laboratory. Complete development of thrips from both populations occurred at temperatures ranging from 20 to 30°C. Two approaches were used to model the predicted distributions of the thrips populations in the USA: the physiological model (NAPPFAST) based on cold tolerance and the ecological niche model based on climatic variables (MaxEnt). The physiological model predicted that both populations of P. ichini may establish in similar areas of the USA, overlapping with the distribution of Schinus. However, the niche model predicted that only the Ouro Preto thrips could establish in the USA. The difference in model predictions suggests an apparent preadaptation of the Salvador thrips to lower temperatures than those experienced at the locations they were collected in Brazil. The Ouro Preto thrips had similar fecundity on two Florida Schinus haplotypes, whereas lower fecundity on haplotype A was found for the Salvador thrips. Based on these results, the Ouro Preto population may be better adapted to the climatic conditions and plant haplotypes found in Florida. Moreover, greenhouse studies indicated that Schinus growth was greatly reduced by thrips feeding, which may result in lower weed reproduction and densities in the field. 相似文献
