Mosquitoes buzz and fruit flies don’t - a comparative aeroacoustic analysis of wing-tone generation

The objective of the research were to investigate level parasitization, immature development period, longevity of adult parasitoids, along with number of progeny and parasitoid sex of Psyttalia sp. attacking larvae of Bactrocera dorsalis. This experiment was conducted in Laboratory of Entomology, Department Plant Pest and Diseases Faculty of Agriculture, Sriwijaya University from March to September 2007. The result showed that the average level of parasitization of Psyttalia sp. reached 24.24%. The highest one was 30% and the lowest was 16.7%. The immature development period of Psyttalia sp. ranged from 24-31 days with average 27.5 days. Longevity of imago parasitoids which stored at 5 0C was 14.1 days. In the research, the progeny of parasitoids which produced was females with percentage of females reached 59.99% and percentage of males reached 39.99%.Keywords: fruit flies, Bactrocera dorsalis, parasitoid, Psyttalia sp.

Psychological Capacities

Many people accept that chimpanzees, dolphins, and some other animals can think and feel. But these cases are just the tip of a growing iceberg. If biologists are right, fruit flies and plants make decisions, worms and honeybees can be trained, bacteria communicate linguistically, and neurons have preferences. Just how far does cognition go? This book is the first to critically consider this question from the perspective of the entire range of new ascriptions of psychological capacities throughout biology. It is also the first to consider the role of mathematical models and other quantitative forms of evidence in prompting and supporting the new ascriptions. It defends a default literal interpretation of psychological terms across biological domains. It also considers the implications of the literal view for efforts to explain the mind’s place in nature and for traditional ways of distinguishing the superior moral status of humans relative to other living beings.

Electro Optic Modulator

Doubled frequency optical two-tone generation and optical single sideband (SSB) modulation by the dual-electrode-type electro-optic (EO) modulator with a single Mach–Zehnder (MZ) interferometer were considered. We theoretically showed that redundant spectrum components in the modulated optical signals, which are caused by the imbalance of light splitting ratio between the two arms of the interferometer, are significantly suppressed by controlling the input power ratio of RF modulation signals applied to each electrode. This effect was confirmed by the experiment, where an optical two-tone with the redundant components 49.8 dB lower than the primary two-tone components in intensity level was obtained. This method is also valid for suppression of undesired frequency components of RF signals that are generated at a photo detector from the optical two-tone waves propagated through a dispersive optical fiber.
