The female sex pheromone composition and the male electro-physiological response with respect to the three main sex pheromone components, (Z)-5-decenyl acetate, (Z)-7-dodecenyl acetate, and (Z)-9-tetradecenyl acetate, were investigated in populations of Agrotis segetum from Armenia and Bulgaria. The percentage composition of the female-produced pheromone was 1:52:47 and 1:42:57 for the respective

Arbetsmarknaden är idag ansträngd. Faktorer såsom effektivisering av organisationer, skepsis mot att nyanställa samt hög arbetslöshet medför att konkurrensen om arbetena har ökat. Därtill är sjukskrivningstalet högt. Långvarig sjukskrivning kan medföra mänskligt lidande bland annat på grund av att individen kan uppleva känslor av utanförskap samt otrygghet som ett resultat av att denne går miste o

After the American invasion of Iraq in 2003, the Palestinians living there have been targeted for gross human rights abuses including kidnappings, torture and killings. This has lead to a mass flight of Palestinians out of Iraq. The problem for this group of refugees is that they have not been acce

Brottsoffer är ett ord med många konnotationer som har kritiserats för att antyda hjälplöshet och passivitet. Att kategoriseras som brottsoffer är inte alltid välkommet, men medför likväl fördelar, som till exempel möjligheten att driva en rättsprocess och tillgång till stöd och empati.

The article aims at pointing out the limitations of those archaeological approaches in the field of medieval studies that strictly follow the medieval social theory of the three and later four orders/estates. As an example of the possibilities offered by the use of an contextual approach in attempting to transcend the borders of the four-estate model, an analysis and interpretation of the pottery

Song complexity is often regarded as a sexually selected trait that reflects the overall quality of a male. In many passerine species, old males possess larger song repertoires than younger males. This may be either because individual males improve their performance as they get older (longitudinal increase) or because poor singers have reduced viability and, hence, are underrepresented in old age

The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S
