21. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer
Sammanfattning : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. LÄS MER
22. Odour detection in the desert locust, Schistocerca gregaria: antennal structure and function
Sammanfattning : The desert locust, Schistocerca gregaria, is a polymorphic insect that occurs in two morphological and physiological distinct phases, solitary and gregarious, depending on population density. The two phases are reversible at any developmental stage. The gregarious phase produces and uses stage-specific pheromones, that keep the swarm together. LÄS MER
23. A pheromone-based toolbox of longhorn beetles (Cerambycidae) for monitoring biodiversity in ephemeral deadwood substrates of oak
Sammanfattning : Forest biodiversity is exhibiting a worldwide decline in response to environmentalchanges that result in the rapid loss, degradation, and fragmentation of essential foresthabitats. Saproxylic insects, especially beetles, are an important part of forestbiodiversity by contributing to deadwood decomposition, and serving as importantcomponents of food webs. LÄS MER
24. On the way of making plants smell like moths - a synthetic biology approach
Sammanfattning : Moth caterpillars are major agricultural pests in many parts of the world. In general female moths attract male mates with their pheromone over long distance. Most of the described moth pheromones belong to the same class of chemical compounds, fatty acid derivatives that are produced de novo in the pheromone gland. LÄS MER
25. Pyralid moth reproduction: Communication, Constraints & Control
Sammanfattning : Olfactory cues play an important role in the reproduction of three pyralid moths, the Indian meal moth (Plodia interpunctella), the Mediterranean flour moth (Ephestia kuehniella) and the almond moth (E. cautella). Both males and females of P. interpunctella are capable of multiple matings. LÄS MER
