Résumé :
AbstractLarvae of the predatory gall midge Feltiella acarisuga (Vallot) diapaused as prepupae in tightly woven, brown, silk cells on leaf surfaces. Photoperiod alone, at day lengths from 16 to 8 h did not induce diapause at either 20 or 25 °C. A low incidence of diapause was induced by a combined photoperiod and thermoperiod of an 8-h day at 25 °C and a 16-h night at 15 °C. The incidence of diapause was higher under these conditions if the larvae were fed diapausing spider mites, Tetranychus urticae (Koch) (Acari: Tetranychidae).

Résumé :
Aby przetrwać niekorzystne, występujące cyklicznie w ciągu roku warunki środowiska, owady wytworzyły różne mechanizmy adaptacyjne. Jednym z nich jest diapauza, szeroko rozpowszechniona, pozwalająca przetrzymać krytyczny okres oraz zsynchronizować rozwój i procesy rozrodcze do warunków panujących w środowisku. Diapauza może być zjawiskiem obligatoryjnym występuje w każdym pokoleniu, niezależnie od warunków w jakich żyją owady, lub fakultatywna, pojawiające się tylko w odpowiedzi na zmiany natężenia określonych czynników.

Résumé :
AbstractMuch progress has been made in understanding the environmental and hormonal systems regulating winter diapause. However, transcriptional regulation of summer diapause is still largely unknown, making it difficult to understand an all-around regulation profile of seasonal adaptation. To bridge this gap, comparison RNA-seq to profile the transcriptome and to examine differential gene expression profiles between non-diapause, summer diapause, and winter diapause groups were performed. A total number of 113 million reads were generated and assembled into 79,117 unigenes, with 37,492 unigen

Résumé :
Aedes togoi (Theobald) from Vancouver, B.C., may enter diapause in either the egg or larval stage. Larval diapause occurred in the fourth instar, when immatures were maintained at 16 °C or less, at photoperiods shorter than 12 h light/day. The critical photoperiod was calculated as 10.9L:13.1D at 16 °C. Larvae that failed to pupate after 40 days following hatching were recorded as being in diapause. At light periods greater than 12 h at 16 °C, there was no larval diapause and, at 14 °C, 100% of the larvae diapaused at 10L:14D. Temperatures of 18 °C or higher, at 10L:14D, prevented larval diapa

Résumé :
Diapause is a reversible developmental arrest faced by many organisms in harsh environments. Annual killifish present this mechanism in three possible stages of development. Killifish are freshwater teleosts from Africa and America that live in ephemeral ponds, which dry up in the dry season. The juvenile and adult populations die, and the embryos remain buried in the bottom mud until the next rainy season. Thus, species survival is entirely embryo-dependent, and they are perhaps the most remarkable extremophile organisms among vertebrates. The aim of the present study was to gather informatio

Résumé :
Avian blastoderm can enter into diapause when kept at low temperatures and successfully resume development (SRD) when re-incubated in body temperature. These abilities, which are largely affected by the temperature and duration of the diapause, are poorly understood at the cellular and molecular level. To determine how temperature affects embryonic morphology during diapause, high-resolution episcopic microscopy (HREM) analysis was utilized. While blastoderms diapausing at 12 °C for 28 days presented typical cytoarchitecture, similar to non-diapaused embryos, at 18 °C, much thicker blastoderms

Résumé :
AbstractPidorus euchromioides Walker has two separate diapauses during its life cycle, a winter diapause as a fourth larval instar and a summer diapause as a prepupa in a cocoon. Winter diapause was induced by short photoperiods. The critical day length of 13 h 20 min to 13 h 40 min at 23.3°C under insectary conditions was very similar to the critical day length (13 h 32 min) observed in the field. Sensitivity to day length was restricted to the first 9 days, corresponding to the first and second instars. The duration of larval diapause was not only strongly correlated with the inducing photop

Many holometabolous insects hibernate by triggering diapause, an “actively-induced” dormancy that blocks developmental functions. Yet, the nature of signals enhancing the plasticity of developmental system and underlying diapause inducibility is still elusive. We show that the “Insulin/IGF” dilp2/5 genes, encoding for developmental hormones, antagonize diapause switch in D. melanogaster and their modulation is pivotal in sensitizing the developmental system to environmental perturbations. Functional impairment of dilp2/5 signaling results in the appearance, or inhibition, of the inducible diap

Résumé :
The total gestation period in the roe deer is approximately 290 days (10 months). When the blastocyst reaches the 20-30 stage it enters a 5-month period of diapause. During the last six weeks of diapause the blastocyst undergoes mitosis and reactivates in late December or early January at the 100-cell stage. The conceptus undergoes a period of rapid growth, which lasts between 7 and 25 days, before attachment to the endometrium and normal fetal growth. By studying the period between late diapause and early fetal development, it was possible to monitor changes in the reproductively important ho

Résumé :
As a strategy to survive to the upcoming winter, many insects enter diapause (a typical overwintering response that results on their developmental arrest). Drosophila melanogaster undergoes an adult or reproductive diapause that can be easily spotted by looking at the stage of development of the females’ ovaries. The possibility of the circadian clock influencing this phenotype was proposed to explain photoperiodic differences in induction levels. Nevertheless, to the date the debate is still on.

In this work I used time lapse brightfield microscopy to investigate cells division’s kinetics during the first developmental stages of annual- and non-annual species belonging to the three different hylogenetic clades. Annual killifishes of all three clades had cleavage times significantly longer when compared to their non-annual sister taxa (average 35 min vs. average 75 min), showing, for the first time, that cell cycle rate during cleavage, a trait thought to be rather volutionary conserved can undergo convergent evolutionary change in response to variations in life-history.

Résumé :
The general objective of this study was to develop rationally designed mimetic antagonists (and agonists) of the PK/PBAN Np class with enhanced bio-stability and bioavailability as prototypes for effective and environmentally friendly pest insect management agents. The PK/PBAN family is a multifunctional group of Nps that mediates key functions in insects (sex pheromone biosynthesis, cuticular melanization, myotropic activity, diapause and pupal development) and is, therefore, of high scientific and applied interest. The objectives of the current study were: (i) to identify an antagonist bioph

Résumé :
The false codling moth (Thaumatotibia leucotreta) is a major polyphagous pest native to sub-Saharan Africa, affecting over 50 crop species, including citrus, stone fruits, nuts, arable crops, grapevines and vegetables. Larval feeding causes significant damage to fruits, leading to premature ripening and yield losses. The pest, present year-round due to its lack of diapause, is found in African countries and Israel and can spread through trade. Strict phytosanitary measures are required to prevent its spread, impacting trade markets. There are no classical biological control programs for this p

Résumé :
The proposed research was directed at determining the activation/binding domains and gene regulation of the PBAN-R’s thereby providing information for the design and screening of potential PBAN-R-blockers and to indicate possible ways of preventing the process from proceeding to its completion. Our specific aims included: (1) The identification of the PBAN-R binding domain by a combination of: (a) in silico modeling studies for identifying specific amino-acid side chains that are likely to be involved in binding PBAN with the receptor and; (b) bioassays to verify the modeling studies using mut

Résumé :
The original objectives of the approved proposal included: (a) The determination of species- and tissue-specificity of the PBAN-R; (b) the elucidation of the role of juvenile hormone in gene regulation of the PBAN-R; (c) the identificationof the ligand binding domains in the PBAN-R and (d) the development of efficient screening assays in order to screen potential antagonists that will block the PBAN-R. Background to the topic: Moths constitute one of the major groups of pest insects in agriculture and their reproductive behavior is dependent on chemical communication. Sex-pheromone blends are
