Black locust is one of the most commonly planted exotic tree species in world. It has a crucial role mitigating negative effects climate change. Its increment analyses have key forest planning. Increment added to wood stock over and again, only this continuous replenishment makes sustainable management possible. This study presents results analysis periodic annual (PAI) by diameter (dbh) volume...

Black locust is an interesting option for biomass production at sites prone to water shortage because the species combines water-use efficiency and a yield largely superior that of poplars under conditions study. (Robinia pseudoacacia L.) tree woody production. However, its potential this purpose has been much less studied characterized than from Salicaceae family (i.e., poplar willow). The obj...

The aim of this paper is to analyze the mechanical properties Robinia pseudoacacia L. (black locust), Platanus × hybrida Brot. (London plane), Ulmus pumila (Siberian elm), and Populus alba (white poplar), estimated using ultrasound wave equipment (USLab y Sylvatest Duo) impact (Microsecond Timer) on standing trees, felled logs specimens obtained from different parts trees. Bending strength, axi...

Biosynthesis of locust apolipophorin-111 (apo-111) was studied in vitro. Gel electrophoresis and immunoblotting analyses of the locust hemolymph demonstrated that apo-111 first appears in the hemolymph on the day 3 of the adult stage after the final molt and its hemolymph concentration increases thereafter. When incubated in vitro in a medium containing radioactive amino acid, the fat body cell...

Locust outbreaks have long been a very serious problem for agriculture and livelihoods in many countries globally. This article is an introduction to Special Issue of the journal Agronomy devoted management these pests. Although not exhaustive, nineteen articles herein cover variety species, regions world aspects pest locust research early 21st century. book source information reflection, as we...

Under certain environmental and population conditions some species (the locusts) of Acridid Orthoptera swarm and are capable of migrating hundreds of miles using flight as the primary means of locomotion. Locust flight is a behavior that lends itself to analysis from many approaches and that has attracted considerable research attention for many years. In particular the role of the nervous syst...

Locust flight is of interest to neurophysiologists as an example of simple repetitive behaviour easily observable in the laboratory and susceptible to single-unit analysis. Flight aerodynamics (Weis-Fogh, 1956), muscle activity patterns (Wilson, 1961; Wilson & Weis-Fogh, 1962) and sensory regulation (Wilson & Gettrup, 1963; Gettrup & Wilson, 1964; Gettrup, 1966) have been intensively examined. ...

Odorant binding proteins (OBPs) play an important role in insect olfaction, facilitating transportation of odorant molecules in the sensillum lymph. While most of the researches are concentrated on Lepidopteran and Dipteran species, our knowledge about Orthopteran species is still very limited. In this study, we have investigated OBPs of the desert locust Schistocerca gregaria, a representative...

The locust olfactory system interfaces with the external world through antennal receptor neurons (ORNs), which represent odors in a distributed, combinatorial manner. ORN axons bundle together to form the antennal nerve, which relays sensory information centrally to the antennal lobe (AL). Within the AL, an odor generates a dynamically evolving ensemble of active cells, leading to a stimulus-sp...
