Grasshoppers are divided into two major subgroups: the short-horned grasshoppers (Figure 1) and the long-horned grasshoppers, Mormon crickets and katydids (Figure 2). Short-horned grasshoppers are responsible for most of the reported crop losses. As a result, individuals of this subgroup are popularly referred to as “grasshoppers.” Figure 1. A mature two-striped female grasshopper (Melanoplus b...

Gesonula punctifrons (Stal,1861) a common acridid of same age group were considered and treated with Arsenic salt. ChE activity was found to be increased between 3 and 6 times in compared to the control with the advancement of doses during the experiment of 96 hours. Such huge increase in the activity was probably due to cholinergic imbalance in the brain. Our present study indicated the conspi...

This paper presents a visibility analysis tool for 3D urban environments and its possible applications for urban design practice. Literature exists for performing visibility analysis using various methods and techniques, however, tools that result from such research are generally not suitable for use by designers in practice. Our visibility analysis tool resides in Grasshopper, Rhino. It uses a...

Mounting scientific evidence indicates that pathogens can regulate insect populations. However, limited dispersal and sensitivity to abiotic conditions often restricts pathogen regulation of host populations. While it is well established that arthropod biological vectors increase pathogen incidence in host populations, few studies have examined whether arthropod mechanical vectors (an organism ...

Autonomous mobile robots have become very popular and essential in our life, especially industry. One of the crucial activities robot is planning path from a start point to target point, avoiding obstacles environment. Recently, received more attention, many methodologies been proposed. Path studies shown effectiveness swarm intelligence complex known or unknown environments. This paper present...
