Susceptibility of Tortrix viridiana L. to Bacillus thuringiensis var. kurstaki at different level of larval development.

2009

Recently out-breaks of the green oak leaf roller Tortrix viridana L. (Lepidoptera, Tortricidae) were recorded in Natural Reserve in Sicily (Italy) where treatments are generally forbidden. The commercial, social and environmental value of the wood in the forest needs to be preserved and biological control could be applied in particular case. To optimise the permitted biological treatment, not only in terms of product amount but also for the time of application baseline susceptibility of T. viridiana from the Natural Reserve of Ficuzza (Palermo, Italy) to a commercial formulation of Bacillus thuringiensis was determined for neonates and 2, 5, 10 and 15 day old larvae. The differences in susc…

Inflamed adult pharynx tissues and swimming larva of Ciona intestinalis share CiTNFalpha-producing cells.

2010

In situ hybridisation and immunohistochemistry analyses have shown that the Ciona intestinalis tumour necrosis factor alpha gene (CiTNFalpha), which has been previously cloned and sequenced, is expressed either during the inflammatory pharynx response to lipopolysaccharide (LPS) or during the swimming larval phase of development. Granulocytes with large granules and compartment/morula cells are CiTNFalpha-producing cells in both inflamed pharynx and larvae. Pharynx vessel endothelium also takes part in the inflammatory response. Haemocyte nodules in the vessel lumen or associated with the endothelium suggest the involvement of CiTNFalpha in recruiting lymphocyte-like cells and promoting the…

Developmental speed affects ecological stoichiometry and adult fat reserves in Drosophila melanogaster

2020

Abstract The elemental composition of organisms belongs to a suite of functional traits that change during development in response to environmental conditions. However, associations between adaptive variations in developmental speed and elemental body composition are not well understood. We compared body mass, elemental body composition, food uptake and fat metabolism of Drosophila melanogaster male fruit flies in relation to their larval development speed. Slowly developing flies had higher body carbon concentration than rapidly developing and intermediate flies. Rapidly developing flies had the highest body nitrogen concentration, while slowly developing flies had higher body nitrogen lev…
