Control of insect vector populations is an integral part of disease management but has many challenges. Area-wide campaigns, mainly based on insecticide administration, are most effective for control of insect populations, whereas disease prevention is more localised and protects a smaller number of animals against insect vector contact. Various control and prevention techniques are available f...

Latin abbreviations and words have been used in the zoological literature since Linnaeus (1758), although some are now rare but were in common usage in the 18th and 19th centuries. The following list of Latin abbreviations and words is prepared to help students of scale insects who are not acquainted with Latin and those who may be just beginning to learn about the study of scale insects with i...

Due to the feeding on prickly shrub of Astragalus adscendes by an insect (Cyamophila dicora Loginva), a kind of the manna named Gaz-angubin is produced which it’s harvesting has a long history in Isfahan province. This manna is exclusively produced in Isfahan, Iran. In this research, a map of spatial distribution of this prickly shrub was provided. By random-systematic sample of line transects,...

The specificity of the interactions between plants and their consumers varies considerably. The evolutionary and ecological factors underlying this variation are unclear. Several potential explanatory factors vary with latitude, for example plant species richness and the intensity of herbivory. Here, we use comparative phylogenetic methods to test the effect of latitude on host range in scale i...

Background: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...

Geographic automata systems composed of agent-based models (ABM) are capable of representing complex, spatio-temporal phenomena such as insect infestation. However, ABMs are often difficult to understand and explain thus imposing limits of their usefulness. This study proposes the integration of spatial network theory and a geospatial ABM to help provide a more complete depiction of ABM behavio...

Insect flight studies have advanced our understanding of flight biomechanics and inspire micro-aerial vehicle (MAV) technologies. A challenge of centimeter or millimeter scale flight is that small forces are produced from relatively complex wing motions. We describe the design and fabrication of a millimeter-sized wing flapping mechanism to simultaneously control pitch and stroke of insect and ...

background: aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. these insects have been, in some cases, well studied because they are vectors of several diseases. this is the first comprehensive faunistic study of aquatic insects from babol county. the results may provide basic data fo...

The association between the entomophagous Lepidoptera Laetilia coccidivora (Comstock, 1879) is recorded for first time with species of Coccoidea Coccus pseudomagnoliarum (Kuwana, 1914). This phytophagous insect also represents record Mexico. material was obtained from municipality Cortazar, Guanajuato, host plant, Acacia farmesiana (L.) Willd. & Arn., a new as scale insect. voracity larvae ...
