..., but are not accumulated, likely because they have lower energy density than lcTAGs. Here we report that acTAGs comprise 36% of the neutral lipid pool of overwintering prepupae of the goldenrod gall fly, Eurosta solidaginis , while only 17% of the neutral lipid pool is made up of typical lcTAGs. These high concentrations...

...Jason B. Williams; Richard E. Lee, Jr SUMMARY Mechanisms and possible cues for seasonal increases in desiccation resistance in larvae of the goldenrod gall fly Eurosta solidaginis ,were examined before and after natural and premature plant senescence, or after being removed from their gall...

... of the goldenrod gall fly Eurosta solidaginis Fitch (Diptera, Tephritidae). From September to December, hemolymph osmolality(455-926 mOsmol kg l -1 ) and freezing tolerance increased markedly in field-collected larvae. Chlorophenol Red was readily transported into the lumen of the foregut, the posterior portion...

...Valerie A. Bennett; Richard E. Lee, Jr ABSTRACT Although seasonal changes in the freeze-tolerance of third-instar larvae of Eurosta solidaginis have been well documented for the whole organism, the nature of this cold-hardiness at the cellular level has not been examined. Seasonal changes...

...Denis R. Joanisse; Kenneth B. Storey ABSTRACT Antioxidant and pro-oxidant systems were studied in overwintering larvae of two cold-hardy gall insect species, the freeze-tolerant fly Eurosta solidaginis and the freeze-avoiding moth Epiblema scudderiana . An increase in the levels of the oxidized...

...John A. Mugnano; Richard E. Lee, JR; Richard T. Taylor ABSTRACT During the autumn, the third-instar larvae of the gall fly Eurosta solidaginis acquire freeze tolerance and their crystallization temperatures increase into the −8 to −10 °C range. Despite conflicting reports, efficient endogenous ice...
