(Z,Z,Z)‐1, 3, 6, 9‐Heneicosatetraene was identified as a sex pheromone component of Epirrita autumnata (Borkhausen), (Lepidoptera: Geometridae). Gas chromatography coupled with electroantennographic detection revealed one active peak‐from female pheromone gland extracts. The chemical identification of the compound was based on gas chromatography‐mass spectrometry, chemical micro‐reactions and unam

Enantiomer separation of (6 Z,9 Z)-cis-3,4-epoxynonadecadiene and (3 Z,9 Z)-cis-6,7-epoxynonadecadiene could be achieved using chiral high-resolution gas chromatography and a cyclodextrin-bond column. (3 Z,9 Z)-(6 R,7 S)-Epoxynonadecadiene was identified from ovipositor extracts of Colotois pen-Naria, while in Erannis defoliaria the 6 S,7 R-enantiomer was found. In field trapping tests pure synthe

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

The E and Z pheromonal strains of the European corn borer, Ostrinia nubilalis, are characterized by female production of and male preference for opposite blends of (E)-11-and (Z)-11-tetradecenyl acetate. It is known that the pheromone production is controlled by an autosomal gene and that the males' behavior is determined by a sex-linked gene. A third gene, autosomally inherited, has been shown to

First meiotic division in females and males of Yponomeuta evonyrnellus (L.), Y. cagnagellus (Hiibner). Y. rnalinellus Zeller, Y. padellus (L), Y. rorellus (Hiibner) and Y. gigas Rebel was studied in the light microscope. In the heterogametic females the sex chromosomes were found to be associated in a sex chromosome trivalent. The sex chromosome trivalent, written AA W Z, consisted of a W‐chromos

This chapter uses the term adaption in the sense of how a regionally based, popular culture phenomenon has nurtured structural economic transformation. The chapter elaborates a critical examination of the comparative popularity of Nordic noir, asking whether the two long-running film and television crime franchises Wallander (Wallander, (1994–2016) and The Bridge (Bron/Broen, 2011–2018) have been

Background: A contralateral occult inguinal hernia is frequently observed in patients planned for a unilateral laparoscopic inguinal hernia repair. Surgical strategy for contralateral groin management in patients scheduled for an endo-laparoscopic unilateral inguinal hernia repair is controversial and based on questionable evidence. This study aimed to gather international opinion concerning the s

Parasites have evolved a diversity of lifestyles that exploit the biology of their hosts. Some nematodes that parasitize mammals pass via the placenta or milk from one host to another. Similar cases of vertical transmission have never been reported in avian and nonavian reptiles, suggesting that egg laying may constrain the means of parasite transmission. However, here we report the first incidenc

The general assumption in the West is that there still is an inherent difference between persons and things. This divide informs how “the human” and human subjectivity are constructed as distinct from all others. Recently, the distinction has been challenged in posthumanist theory, where it has been argued that the divide between human and nonhuman agents—or rather, bodies—is always an effect of a

Introducing biobased polymers from renewable sources for use as high-performance thermoplastics with high demands on mechanical rigidity, transparency, thermal stability, as well as good processability, is a significant challenge. In the present work we have designed and prepared a rigid biobased bis-spirocylic diol by di-cycloketalization of a bicyclic diketone (cis-bicyclo[3.3.0]octane-3,7-dione

In mammals, the four native deoxyribonucleosides are phosphorylated to the corresponding monophosphates by four deoxyribonucleoside kinases, which have specialized substrate specificities. These four enzymes are likely to originate from a common progenitor kinase. Insects appear to have only one multisubstrate deoxyribonucleoside kinase (dNK, EC 2.7.1.145), which prefers pyrimidine nucleosides, bu

A wind-borne plume of sex pheromone from a female moth or a synthetic source has a fine, filamentous structure that creates steep and rapid fluctuations in concentration from a male moth flying up the plume's axis. The firing rates from single antennal neurons on Agrotis segetum antennae decreased to nearly zero within seconds after the antennae were placed in a pheromone plume 70 cm downwind of a

Non-exhaust wear emissions from disc brakes affect the air quality in cities throughout the world. These emissions come from the wear of the contact surfaces of both the pads and disc. The tribological and emissions performance of disc brakes strongly depend on the contact surface characteristics of the pads and discs. The surfaces of conventional pads are scorched by heating it to several hundred

Jordan has one of the lowest available water supplies in the world; meanwhile Jordan has seen large increase in population and refugee’s fluxes, leading to an increase in water demand [1]. To address this unprecedented water scarcity, Jordan’s water must be used where its social and economic value is highest. Jordan must treat and reuse virtually every drop of water. It is expected to have more th

Cognitive reserve (CR) is thought to protect against the consequence of age- or disease-related structural brain changes across multiple cognitive domains. The neural basis of CR may therefore comprise a functional network that is actively involved in many different cognitive processes. To investigate the existence of such a “task-invariant” CR network, we measured functional connectivity in a cog
