New data on the records of synanthropic slug species Limacus maculatus and Arion vulgaris in Belarus are analyzed. It is assumed that penetration these into territory occurred from other parts their modern range together with imported goods.

La produccion de peces ornamentales es una actividad importante dentro la acuicultura peruana generando impactos socioeconomicos positivos en toda cadena valor. El pez ornamental Platy (Xiphophorus maculatus) uno los mas coloridos utilizados ampliamente como un sistema modelo animal para comprender base genetica del polimorfismo patron color. coloracion X. maculatus esta relacionada con sintesi...

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the che...

In an era of global warming, the negative effects temperature stress on fertility could intensify predicted losses biodiversity. Male is particularly sensitive to stress, yet we have incomplete understanding when, during reproductive ontogeny, spermatogenesis most affected. Here, used a temperature-switch protocol identify when development affects expression sperm length and testes size in bruc...

Con el fin de profundizar en conocimiento sobre los efectos determinados insectos registro óseo la Depresión del río Salado, se desarrolló un experimento actualístico con especie Dermestes maculatus (Coleoptera: Dermestidae) y restos actuales cuatro especies fauna diferentes tamaños (Myocastor coypus, Dasypus hybridus, Ovis aries, Oryctolagus cuniculus). D. es coleóptero cosmopolita que coloniz...

One new species named Goeldichironomus adhaerens sp. n. is described from urban area in Manaus, Brazilian Amazon, based on male adult, pupa and larva. New records of G. neopictus Trivinho-Strixino & Strixino, G. maculatus Trivinho-Strixino & Strixino, G. pictus Reiss and G. fluctuans Reiss are also provided.

Environmental factors (biotic and abiotic) are major depletion reasons in granaries. Fungi insect pests act synergistically deterioration of grains storages which results nutritional damage to the stored food becomes unpalatable for consumer. There is a need establish timeline synergistic caused by mycotoxigenic fungi better management. For this purpose, interaction (Aspergillus flavus, Aspergi...

Evolutionary responses to selection can be complicated when there is substantial nonadditivity, which limits our ability to extrapolate from simple models of selection to population differentiation and speciation. Studies of Drosophila melanogaster indicate that lifespan and the rate of senescence are influenced by many genes that have environment- and sex-specific effects. These studies also d...

Genetic differentiation can be promoted allopatrically by geographic isolation of populations due to limited dispersal ability and diversification over time or sympatrically through, for example, host-race formation. In crop pests, the trading of crops across the world can lead to intermixing of genetically distinct pest populations. However, our understanding of the importance of allopatric an...

Inbreeding generally reduces male mating activity such that inbred males are less successful in male-male competition. Inbred males can also have smaller accessory glands, transfer less sperm and produce sperm that are less motile, less viable or have a greater frequency of abnormalities, all of which can reduce the fertilization success and fitness of inbred males relative to outbred males. Ho...
