owe much of their extraordinary evolutionary success to flight. Compared with their flightless ancestors, flying insects are better equipped to evade predators, search food sources and colonize new habitats. Because their survival and evolution depend so crucially on flight performance, it is hardly surprising that the flight-related sensory, physiological, behavioral and biomechanical traits o...

Plants have evolved a variety of ways to defend themselves against biotic attackers. This has resulted in the presence of substantial variation in defense mechanisms among plants, even within a species. Genome-wide association (GWA) mapping is a useful tool to study the genetic architecture of traits, but has so far only had limited exploitation in studies of plant defense. Here, we study the g...

Collections of biological specimens are fundamental to scientific understanding and characterization of natural diversity-past, present and future. This paper presents a system for liberating useful information from physical collections by bringing specimens into the digital domain so they can be more readily shared, analyzed, annotated and compared. It focuses on insects and is strongly motiva...

essential oil extracted from the leaves of myrtle, myrtus communis l. (myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (tribolium confusum and callosobruchus maculatus). the chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (gc-ms). the major oil components were α-pinene (10.4%), α- terpineol (10.1%), linalool (9.0%...

Synthetic insecticides and repellents have been broadly used worldwide for the control of crop pests and insects acting as vectors of human disease. Despite effectiveness, synthetic insecticides or repellents may cause serious damages to the environment and consequently to humans and animals. The growing biotechnological investigation for alternative insecticides and repellents, particularly of...

Introduction. Mango (Mangifera indica L.) is widely cultivated around the world and in Costa Rica nearly 8200 hectares are dedicated to production of this crop. More than 400 species phytophagous insects mites have been reported on mango worldwide. Among them 73 armored scale (Hemiptera: Diaspididae), which Aulacaspis tubercularis Newstead one most serious pests mangos many parts world. Objecti...

In this paper, we study the effect of demand on specialization of skilled agents by modifying the earlier hybrid model which is based on the well-known Genetic Threshold Model (GTM) and Social Inhibition Model (SIM). We improve the agent specialization or division of labor (DOL) and also the quality of work (QOW) by introducing a new concept of varying the demand on a smooth curve and compare o...

Parallel trends of chromosomal evolution in Aphidococca are discussed, based on the catalogue of chromosomal numbers and genetic systems of scale insects by Gavrilov (2007) and the new catalogue for aphids provided in the present paper. To date chromosome numbers have been reported for 482 species of scale insects and for 1039 species of aphids, thus respectively comprising about 6% and 24% of ...

the german cockroach, blattella germanica, is one of the most common pest species, and is acarrier of many pathogen and allergen factors in humans. thus, regarding public health, the control of thisinsect is quite important. dietary use of hormone analogues, especially juvenoids which disrupt reproductiveorgan development, is a relatively new method to control cockroaches. in this study, the ef...
