Host age selection behaviour of Trichogramma aurosum Sugonjaev & Sorokina (Hymenoptera: Trichogrammatidae)

Host age selection in several German strains of Trichogramma aurosum Sugonjaev & Sorokina was examined in laboratory choice tests under direct observation for 90 min., in order to select candidate strains for attempts at controlling the codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae). Experiments were conducted at room temperature by exposing combinations of two host ages (zero vs. 4 and 1 vs. 5-day old) to a single female wasp. Host age did not appear to affect the wasps parasitization behaviour, although they spent longer time drilling on old eggs (4 and 5 days old) compared with fresh ones (0 and 1 day old). This not necessarily means that they preferred fresh eggs over old ones, since both type of hosts were parasitized in the choice test. Possibly an increased mechanical resistance of the chorion of older eggs was responsible for the prolonged drilling time. Mean drumming time was independent of host age. Mean duration of drilling and drumming was in general longest in the first and last egg attacked by all T. aurosum strains tested and for all host ages. Drilling time consumed more than 80% of the mean handling time of all strains tested for all host ages, followed by resting and walking

Ehlers-danlos Syndrome Type Iv And Multiple Aortic Aneurysms. A Case Report

Beside atherosclerosis, aortic aneurysms can be part of the clinical spectrum of many systemic diseases, including infectious, inflammatory, genetic and, less often, congenital disorders. A 48-year-old white man presented with multiple large aneurysms of the aorta and its main branches. Medical history was unremarkable except for the presence of a softened abdominal mass since he was 28 years old. On the physical examination, an arterial murmur was heard over the left carotid artery and a palpable mass was noted in the whole right side of the abdomen. No skin or joint abnormalities were noted. Aortography, computed tomography, and magnetic resonance angiography showed multiple large aneurysms of the descending thoracic and abdominal aorta. Aneurysms of the innominate, left subclavian, and carotid arteries were also seen. This case resembles those previously reported, in which multiple aortic aneurysms were associated with abnormalities of the type III procollagen gene (COL3A1). Although the classic stigmas of the Ehlers-Danlos syndrome type IV were lacking, this genetic disease may be the cause of the multiple aneurysms in this patient.523223228Desforges, J., Abdominal aortic aneurysm (1993) N Engl J Med, 328, pp. 1167-1172Reed, D., Reed, C., Stemmermann, G., Are aortic aneurysms caused by atherosclerosis?
