BACKGROUND Retroelements can successfully colonize eukaryotic genome through RNA-mediated transposition, and are considered to be some of the major mediators of genome size. The migratory locust Locusta migratoria is an insect with a large genome size, and its genome is probably subject to the proliferation of retroelements. An analysis of deep-sequencing transcriptome data will elucidate the s...

A lipid transfer particle (LTP) from the hemolymph of adult male locusts, Locusta migratoria, was isolated and purified. The locust LTP exhibited its capacity to catalyze the exchange of diacylglycerol between low density lipophorin (LDLp) and high density lipophorin (HDLp). Contrary to the LTP reported for the tobacco hornworm, M. sexta, the locust LTP appeared to lack the capacity to promote ...

The brain of the locust Schistocerca gregaria contains a nitric oxide synthase (NOS) that has similar properties to mammalian neuronal NOS. It catalyses the production of equimolar quantities of nitric oxide (NO) and citrulline from l-arginine in a Ca2+/calmodulin- and NADPH-dependent manner and is inhibited by the Nomega-nitro and Nomega-monomethyl analogues of l-arginine. In Western blots, an...

The difficulty lies not in new ideas, but in escaping from old ones. Preface The desert locust is an ancient problem. People in Africa, the Middle East and parts of Asia had to live and cope with it for many centuries. It is only with the development of chemical pesticides that man developed the belief he could solve this problem by adopting a strategy of war against nature. Spraying poisonous ...

The main goal of the investigation was to measure and estimate thermal stability pinosylvin, pinosylvin monomethyl ether, robinetin, dihydrorobinetin, i.e., characteristic compounds wood Scots pine black locust, respectively. pure were analyzed with chromatography before after they steam-sterilized oven-dried. Detailed thermogravimetric analysis followed check decomposition stilbenes flavonoids...

Over the past decade, technological advances in experimental and animal tracking techniques have motivated a renewed theoretical interest in animal collective motion and, in particular, locust swarming. This review offers a comprehensive biological background followed by comparative analysis of recent models of locust collective motion, in particular locust marching, their settings, and underly...

It is becoming increasingly clear that global warming is taking place; however, its long-term effects on biological populations are largely unknown due to lack of long-term data. Here, we reconstructed a 1,910-y-long time series of outbreaks of Oriental migratory locusts (Locusta migratoria manilensis) in China, on the basis of information extracted from >8,000 historical documents. First by an...

The salivary glands of the cockroach and locust are innervated primarily from two pairs of motoneurones, designated SN1 and SN2, in the suboesophageal ganglion. Intracellular cobalt fills and subsequent silver intensification were used to reveal the morphology of these cells in both species. Fluorescent microscopy, following treatment of the ganglion with glyoxylic acid, showed that in both spe...

In this study, we aimed to develop height growth models using forest data with the measured total height, bole and diameter at breast targeting Robiniapseudoacacia plantations of various ages, located in restoration former mining areas a lignite center Northwestern Greece. To achieve goal, 24 circular plots were randomly established different ages. Eleven tested for fit, selection was based on ...
