Gall insects can avoid and alter indirect plant defenses.
Parasitic species can dramatically alter host traits. Some of these parasite-induced changes can be considered adaptive manipulations that benefit the parasites. Gall-inducing insects are parasites well known for their ability to alter host-plant morphology and physiology, including the distribution of plant defensive compounds. Here it was investigated whether gall-inducing species alter indir...
متن کاملObservations on Some Causes of Gall Stone
In the present paper and others to succeed it we shall report experiments on the causation of gall stones. Whatever the significance of our findings, or lack thereof, there can be no doubt that the problem of cholelithiasis waits upon the development of an experimental material. The literature of the subject, like that of many another medical theme, exhibits the difficulties which sometimes eff...
متن کاملObservations on Some Causes of Gall Stone Formation
Gall stones frequently form in dogs intubated for the collection of bile under sterile conditions, in the absence of stasis and of gall bladder influence. The stones consist almost entirely of two substances-calcium carbonate and calcium bilirubinate-and they are remarkably uniform in character, as would follow from the limiting conditions of their development. They are not the result of bile l...

متن کاملOxidative stress and antioxidants in overwintering larvae of cold-hardy goldenrod gall insects
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 form of glutathione suggested slight oxidative stress in both species during the winter. Freeze-tolerant Eurosta solidaginis larvae generally had de...
