Courtship, Mating, and Sex Pheromones in the Mealworm Beetle (Tenebrio molitor)
2003
Publisher Summary This chapter focuses on courtship and mating in a coleopteran, the yellow mealworm beetle (Tenebrio molitor), observation and description of the behavior of (relatively) undisturbed animals, and the response of male Tenebrio molitor to the female sex attractant pheromone. Pheromones used in communication between members of the opposite sex in a mating context are collectively termed sex pheromones. In many insect species, detection of a sex pheromone is often sufficient to initiate the species-typical courtship and mating behaviors, although the release of these behaviors can be modified by visual, tactile, acoustic, or other types of stimuli. For example, upon detecting a…
Chemosensory cues allow male Tenebrio molitor beetles to assess the reproductive status of potential mates
2004
Males of many insect species, including beetles, choose their mates according to their reproductive status. However, the ways in which male beetles evaluate female reproductive status have received little attention. We tested the existence of male mate choice in the mealworm beetle, Tenebrio molitor, by observing mating and courtship behaviour of males given simultaneous access to pairs of females differing in their reproductive status: (1) mature versus immature; (2) virgin versus previously mated; (3) familiar (mated with the experimental male) versus unfamiliar (mated with a different male). Males courted and mated preferentially with mature and virgin females. To determine whether chemi…
Voila, a New Drosophila Courtship Variant that Affects the Nervous System: Behavioral, Neural, and Genetic Characterization
1998
InDrosophila melanogaster, a specificPGAL4transposon induces theVoila1genetic variant and produces multiple phenotypes. HomozygousVoila1/1flies rarely reach adulthood, whereas heterozygousVoila1/+adult males show strong bisexual behavior. Males with a single copy ofVoila1driving the feminizing transgeneUAS-transformershow very reduced sexual activity but no overall effect on their behavior.Voila1is specifically expressed in the nervous system. In the CNS, it is expressed mainly in the mushroom bodies and, to a lesser extent, in the antennal lobes. In the peripheral nervous system, GAL4 expression is almost entirely restricted to the gustatory sensilla. Using chromosomal deficiencies, the be…
Implication of an odorant-binding protein in precopulatory behaviour and interaction with the bacterial microbiota
2023
Chemoreception allows animals to detect nutritive food and avoid toxic compounds. Volatile and non-volatile chemical compounds, which are detected by olfactory and gustatory sensory organs, can trigger feeding and reproductive behaviours in animals such as Drosophila melanogaster. Inside chemosensory organs, perireceptor proteins like odorant-binding proteins (OBPs) serve to transport odorant and tastant molecule to dedicated receptors. OBPs are not only involved in chemoreception but also in several other functions. A recent study revealed an interaction between insect microbiota and OBP expression while another one showed that microbes can promote nutrient harvesting on food. In our proje…

The effect of male-male competition and ornament size on mean and variance of courtship intensity towards heterospecific and conspecific females
2015
Discrimination between hetero- and conspecifics is the elementary choice an individual performs when searching for potential mates. The level of selectivity and strength of species discrimination is modified by variance in the quality of females, level of the male’s reproductive investment, mate search costs, and the competitive environment. The effect of the competitive environment on both species discrimination and conspecific mate choice has seldom been studied simultaneously. We experimentally manipulated territorial competition ofCalopteryx splendensdamselfly males in the wild, and asked two questions. First, does increased competition influence the territorial males’ responses towards…
Stan techniczny i wykorzystanie zabudowań po klasztorach skasowanych w guberni wołyńskiej w latach 1832–1853 w świetle raportu wołyńskiego gubernator…
2019
W trakcie XIX-wiecznych kasat klasztorów na obszarze cesarstwa rosyjskiego względy ekonomiczne stanowił istotny, może najważniejszy, ale niejedyny czynnik, uwzględniany przy podejmowaniu decyzji o zniesieniu domu zakonnego. Oficjalnie władze rosyjskie głosiły, że cały majątek klasztorny miał być wykorzystany na utrzymanie szkół oraz instytucji opiekuńczych i charytatywnych. W rzeczywistości przejęte ziemskie dobra klasztorne zasiliły skarb publiczny, a mienie z różnych powodów niezbywalne powiększyło majątek, pozostający w dyspozycji władz gubernialnych oraz Cerkwi prawosławnej. Władze długo nie doceniały znaczenia zabudowań poklasztornych. Dla większości z nich nie znaleziono nowego użytko…
Mate Sampling and Assessment Procedures in Female Pied Flycatchers (Ficedula hypoleuca)
2010
Models of mate sampling strategies predict that choosiness should decrease throughout the breeding season due to increasing costs of delaying mating. Therefore, individuals who start searching mates relatively late, should spend less time on sampling, and sample fewer candidates compared to early individuals. We observed mate searching behavior of female pied flycatchers (Ficedula hypoleuca) by radio-tracking in study areas with 6–12 unpaired males. Contrary to the prediction, the observed numbers of males sampled by the searching females increased with time, i.e. late arriving females visited more males than early arrivers. However, this seems to be due to more active sampling of males in …

The liability of the shipmaster in early modern law: comparative (and practice-oriented) remarks
2017
This article deals with the liability of the shipmaster in early modern law in civil and common law, focusing on the approach of Italian and (to a lesser extent) also Iberian courts on the one hand, and on that of common law courts (mostly the King's Bench) on the other. The practice-oriented approach is deliberate: the article seeks to understand what the actual position of the carrier was, not how did learned jurists classify it. Once distinguished practice from dogmatic elaborations (especially for the civil law), this work then proceeds to compare the rules applicable in the two different legal systems. Common law courts imposed strict liability on the shipmaster, for it qualified the c…
