Low temperature biology of insects by David L Denlinger( )

18 editions published in 2010 in English and held by 971 WorldCat member libraries worldwide

This book explores the physiological and molecular mechanisms that enable insects to cope with a cold environment and places these findings into an evolutionary and ecological context. An introductory chapter provides a primer on insect cold tolerance and subsequent chapters in the first section discuss the organismal, cellular and molecular responses that allow insects to survive in the cold despite their, at best, limited ability to regulate their own body temperature. The second section, highlighting the evolutionary and macrophysiological responses to low temperature, is especially relevant for understanding the impact of global climate change on insect systems. A final section translates the knowledge gained from the rest of the book into practical applications including cryopreservation and the augmentation of pest management strategies
Photoperiodism : the biological calendar by Randy Joe Nelson( )

21 editions published between 2009 and 2010 in English and held by 824 WorldCat member libraries worldwide

This book examines the role of photoperiod (day length) in timing seasonal adaptations in plants, invertebrates, and vertebrates. The field is poised to make progress in the understanding of seasonal clocks at all levels of analysis, and Photoperiodism brings together experts working in disparate areas to stimulate conversation among investigators from all related disciplines
Insect timing : circadian rhythmicity to seasonality by David L Denlinger( )

16 editions published between 2001 and 2008 in English and held by 443 WorldCat member libraries worldwide

Leading experts in the field bring together diverse aspects of insect timing mechanisms. This work combines three topics that are central to the understanding of biological timing in insects: circadian rhythms, photoperiodism, and diapause. The common theme underlining each of the contributions to this book is an understanding of the timing of events in the insect life cycle. Most daily activities (emergence, feeding, mating, egg laying, etc.) undertaken by insects occur at precise times each day. Likewise, seasonal events such as the entry into or termination from an overwintering dormancy (diapause) occur at distinct times of the year. This book documents such events and provides an up-to-date interpretation of the molecular and physiological events undergirding these activities. The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing mechanisms
Temperature sensitivity in insects and application in integrated pest management by Guy J Hallman( Book )

12 editions published between 1998 and 2021 in English and held by 175 WorldCat member libraries worldwide

This volume summarizes and analyzes recent developments in the use of extreme temperatures - both high and low - to protect stored grains, to control urban pests, and to keep pest populations below economically damaging levels in both greenhouse and field environments. These tactics have become more important due to the loss of key fumigants and the potential for reducing pesticide residues

Insect diapause by David L Denlinger( Book )

2 editions published in 2022 in English and held by 5 WorldCat member libraries worldwide

"Our highly seasonal world imposes environmental challenges for insects. To survive these inimical periods they rely on a diapause (dormancy) mechanism to bridge unfavorable seasons. The origin of the term "diapause" is discussed, as well as its relationship to related forms of dormancy in other animals. Diapause is distinct from quiescence in that it is not an immediate response to an adverse environment but is programmed at an earlier developmental stage, an attribute that enables the insect to take steps in preparation for entering the arrested state. Diapause can occur at any point in the life cycle (embryo, larva, pupa, adult), but when it occurs is species-specific. The chapter summarizes who does it and in what stage, as well as addressing the occurrence of diapause in social insects. The pervasive impact of diapause on the insect life cycle begins prior to diapause and continues well beyond its termination"--

The genetic basis for the evolution of the organization of work in colonies of the honey bee, Apis mellifera (Hymenoptera: Apidae) by Nicholas W Calderone( )

2 editions published in 1988 in English and held by 4 WorldCat member libraries worldwide

Workers belonging to different subfamilies in colonies with naturally-mated queens also exhibited significant variability in the relative frequencies at which they engaged in guarding, pollen foraging, and nectar foraging. These results support the genetic model for worker behavior based on experiments involving selected stocks of honey bees
Protein expression in flesh flies (Sarcophaga) in response to heat shock, cold shock and diapause by Karl H Joplin( )

2 editions published in 1989 in English and held by 3 WorldCat member libraries worldwide

This dissertation examines aspects of protein expression of Sarcophaga in response to high temperature stress, low temperature stress and during diapause initiation and maintenance
The impact of insect diapause on water balance physiology by Jay Alan Yoder( )

2 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide

In this study on water balance in Sarcophaga crassipalpis, I have (1) examined the water balance characteristics of diapausing and nondiapausing pupae; (2) compared the water balance of tropical and temperate pupae; (3) performed quantitative and qualitative analyses on the puparial hydrocarbons and (4) found evidence for a brain factor that elevates puparial hydrocarbon. I also examined (5) the water balance in eggs of the walking stick, Extatosoma tiaratum in both stages of diapause. (1) Diapausing pupae of S. crassipalpis have reduced net transpiration, absorb water vapor at low humidities and have a high critical transition temperature. The enhanced water balance characteristics are important to a diapausing pupa that must conserve its water during the long period of dormancy. (2) Flesh flies from Panama (Peckia abnormis and Sarcodexia sternodontis) lost water at faster rates than nondiapausing pupae from the temperate zone (S. crassipalpis, S. bullata and Musca domestica). Pupal net transpiration is a function of size but the correlation declines as temperature increases. These pupae have limited ability to absorb water and have similar CTT's, but the activation energies were higher for the tropical species, indicating that they lose water faster than temperate zone fly pupae. (3) Puparia from diapausing pupae of S. crassipalpis have twice as much hydrocarbon as nondiapausing pupae. The hydrocarbons are straight-chain and branched alkanes (range of C$\sb{26}$-C$\sb{30}$). A C$\sb{29}$ alkane is unique to diapause. Hydrocarbon biosynthesis occurs by decarbonylation of precursor fatty acids, a mechanism not previously described in insects. (4) Brain extracts from short-day programmed larvae elevate levels of hydrocarbon in nondiapausing pupae. cAMP mimics this effect, thus indicating that this factor is a neuropeptide. (5) Diapausing walking stick eggs of Extatosoma tiaratum utilize atmospheric water at humidities near a$\sb{\rm v}$ 0.33. Absorption rate increases with temperature and no absorption is observed for dead embryos, indicating an active process. This is the first demonstration of water vapor absorption by arthropod eggs
Isolation of diapause-associated clones from the flesh fly, sarcophaga crassipalpis by Steven P Tammariello( )

1 edition published in 1998 in English and held by 2 WorldCat member libraries worldwide

Flow cytometric analysis performed on brains from diapausing and nondiapausing flesh flies confirmed that a G0/G1 cell cycle arrest occurs throughout diapause. This arrest is broken at diapause termination when cells begin to proliferate leading to adult development

Sarcophaga Crassipalpis pupal diapause : a molecular approach by Ronald D Flannagan( )

1 edition published in 1997 in English and held by 2 WorldCat member libraries worldwide

To isolate diapause specific cDNAs, a diapause pupal brain cDNA library was screened using an elimination hybridization technique. The cDNAs that did not hybridize with a complex mixture of cDNA probes constructed from nondiapausing pupae were selected for further screening. 95 clones did not hybridize and were selected for further characterization. The secondary screen involved hybridizing the selected clones against diapause and nondiapause pupal poly(A)+ RNA. We identified 4 diapause upregulated clones and 7 diapause downregulated clones. Further characterization of these clones was accomplished by DNA sequencing and homology searches. Homologies between our cloned cDNAs adn other genes included those linked to cell cycle progression, stress responses and DNA repair processes
Diapause regulation in pharate first instar larvae of the gypsy moth, lymantria dispar by Kyeong-Yeoll Lee( )

1 edition published in 1996 in English and held by 2 WorldCat member libraries worldwide

Two distinct patterns of gut enzyme activity were noted in relation to diapause: low activities of proteases and esterase, and high activity of alkaline phosphatase (ALP). An ALP zymogram showed the presence of a highly mobile isozyme unique to diapause. Pharate larvae treated with KK-42 showed elevated protease and esterase activity, low ALP activity and absence of the diapause-specific ALP isozyme

Physiological and biochemical adaptations to cold and heat stress in flesh flies (Diptera:sacrophagidae) by Zhengping Chen( )

2 editions published in 1990 in English and held by 2 WorldCat member libraries worldwide

1. Low (O$\sp\circ$C) temperature provides protection against cold injury and high (40$\sp\circ$C) temperature elicits a protective response against heat injury in S. crassipalpis. The cold and heat protective responses were found in all developmental stages of the fly and both result in a rapid acquisition of cold or heat tolerance. Protection is quickly lost after the flies are returned to 25$\sp\circ$C. High temperature protects against cold shock injury, but the opposite is not true. Glycerol appears to be responsible for the protection generated by cold but not for the protection generated by heat
