Description: This study used an explorative, individual-based model to evaluate the influences of (1) plant architecture, i.e. dwarf versus standard trees, (2) the use of hail nets, and (3) insect behaviour on the phenology of the codling moth, Cydia pomonella (Lepidoptera: Tortricidae), a major pest in apple orchards worldwide. Body temperatures of the different codling moth stages were approximated by microhabitat temperatures, behavioural response to temperature, and biophysically modelled temperature increments due to absorption of solar radiation. Results indicate a significant influence of habitat parameters on the phenology of the codling moth. Under the simulated conditions, adults appeared up to 6 days earlier in dwarf trees than in standard trees, and up to 5 days later in trees covered with hail nets than in trees without them. In contrast, thermoregulation behaviour, which is documented for the larval and adult stages, appeared to be of relatively low influence on the insect's overall phenology. Model validation using reported pheromone trap catches of male moths agreed with the simulated appearance dates of adults of the overwintered generation. Simulated and observed appearance dates did not deviate when habitat temperature was used, but deviated considerably when standard air temperature was used as driving variable. Considering habitat and behaviour will help to improve current phenology models for the codling moth. ![]() Iphone Hacks: Pushing the Iphone and iPod Touch Beyond Their Limits $34.99 I bought an iPhone recently and was looking around for advanced information on the iPhone when I stumbled across this book. I was thinking this would be a book for novices on how to use advanced features of the phone (advanced from a novice point of view). But I was pleasantly surprised. This is a book for geeks like me. I just had to read only a few pages to find out that this is one awesome book. In a few paragraphs they explain the finer points of what it means to jailbreak your phone, what it means to unlock your phone, what it means when your iPhone is bricked. As somebody else mentioned here, this is not a book for the faint hearted, but if you are willing to experiment and learn and unleash the potential of the iPhone, this book is your best guide. Here is the table of contents. Chapter 1. iPhone and iPod Touch Hacking Basics Chapter 2. Troubleshoot Your iPhone or iPod Touch Chapter 3. Messaging and Communication Chapter 4. Media and Data Chapter 5. Game Emulation Chapter 6. Telephony Hacks Chapter 7. Unlocking and Activation Chapter 8. Customization Chapter 9. Network Hacks Chapter 10. Application Hacks Chapter 11. Development Hacks Chapter 12. Hardware Hacks Index Come join the joyride. ![]() Polyelektrolyt-basierter UV-Schutz f¸«är Biopestizide: Untersuchungen am Beispiel des Cydia pomonella Granulosevirus (CpGV) gegen den Apfelwickler (German Edition) $146.00 Pestizide biologischer Herkunft werden seit l¸«£ngerem erfolgreich zur Bek¸«£mpfung von Erntesch¸«£dlingen eingesetzt. Trotz ihrer Vorteile gegen¸«äber chemischen Mitteln (hohe Wirkspezifit¸«£t, r¸«äckstandsfreier Abbau) besitzen sie einen wesentlichen Nachteil - eine geringe UV- Stabilit¸«£t. In der Arbeit wurden deshalb Untersuchungen zur Erh¸«Óhung der UV-Best¸«£ndigkeit eines viralen Pestizids am Beispiel des Cydia pomonella Granulose Baculovirus (CpGV), das als nat¸«ärliches Pathogen gegen den Apfelwickler eingesetzt wird, durch eine Beschichtung mit Polyelektrolyten (PEL) durchgef¸«ährt. Das Verfahren beruht auf dem Ansatz, die Nanometer gro¸©Īen Virusdauerformen der Baculoviren, durch schichtweises Auftragen von PEL mit UV- absorbierenden Eigenschaften als einzelne Partikel zu umh¸«ällen. Es wurde eine Beschichtungsprozedur mittels optimierter Polymerpaare sowie Polymer-und Viruskonzentrationen entwickelt. Als UV-absorbierende PELs kamen anionische Ligninverbindungen und Varianten dieser Lignine zum Einsatz, die mit Hilfe einer Kationisierungsreaktion hergestellt wurden. Im Laborversuch wurde eine Erh¸«Óhung der UV- Best¸«£ndigkeit durch die Beschichtung bis um Faktor 6,4 erzielt. ![]() Integrated Control of Cydia Species in Apple Orchards - Evaluation of the Potential of Hyssopus Pallidus as Biological Control Agent $64.00 Direct pests such as the codling moth and the oriental fruit moth are a severe problem in apple cultivation. Today, these kind of pests are being control with a variety of control methods, including chemical control, mating disruption and the use of natural antagonists. H. palliuds is a parasitic wasp that has the ability to enter the infested fruit and to parasitize the larva inside the apple, thus resulting in a reduction of the pest population level. H. pallidus parasitizes the codling moth and the oriental fruit moth equally well inside an apple and can therefore be applied as to combat both pests species. Furthermore, it can be cold stored for a certain period of time without loosing its parasitism capacity. As a result, H. palliuds holds the potential to be a used as a strategy in integrated control programs to fight notorious pests in apple cultivation. |
