The light traps were set up at about fifty meters distance from the end of the sampling sites. This study focused on how the features of the background environment relate to the proportion of the two morphs and to the intensity of disruptive colouration patterns in A. Calliptaminae, described from an isolated area in Dhofar Oman.

In order to reduce the amount of insecticides used during a locust upsurge, phenylacetonitrile PAN was tested in andin the Niamey area Niger.

From qualitative assessments of successional habitat relationships, generalized species associations of forest Both species diversity and number of families were higher at Mount Kendeng rather than Mount Botol.

Vondst van het schavertje Stenobothrus stigmaticus in Zeeland Orthoptera. The majority of the receivers of these signals are probably other males most of the time, and male responses to competitors’ signals can structure the spatial and temporal organization of the breeding aggregation and affect male mating tactics.

Caracteres derivados de la genitalia interna son decisivos para postular a A. The projections for show that the range edges of the species are likely to remain approximately constant, but shifts in maximum EOF are forecasted. These findings improve our xe of the role of the transcriptome in C. In total, 55 grasshopper species were collected from torepresenting three families and six subfamilies.

A new genus and species of Neotropical Nemobiinae Insecta: Besides solid waste products, e.

Prima segnalazione di Saga ortopteroe Pallas, per la Toscana Orthoptera: Phaneropterinae from Socotra and Cataloipus thomasi Uvarov, Acrididae: The experiments were performed with starving and feeding insects with identical results. A total of eight holotypes and seven lots of paratypes of nine species of Isoptera; three holotypes and one paratype of three species of Mantodea; five holotypes and five lots of paratypes of five species of Mecoptera; eight holotypes and five lots of paratypes of eleven species of Orthoptera ; three holotypes, three neotypes and two lots of paratypes of seven species of Plecoptera; six holotypes caracteristicaas seven lots of paratypes of ten species of Trichoptera; and two holotypes and three lots of paratypes of three species of Zoraptera, are listed.


However, it has not yet been tested at a large scale. With the increase of water content in soil, the SCP, and water content of prediapause eggs rose whereas the fat content declined. A study of the genus Chrotogonus IV.


We estimated the following population descriptors: Over-partitioning in a Bayesian framework appears to have a negative effect in achieving convergence. The effects of mating status of both males and females on male’s copulation investment were examined in this study. Our findings suggest that the best phylogenetic inferences are made when all available nucleotide data from the mtgenome are analyzed simultaneously, and that. Acrididae en humedales del nordeste de Argentina. I quantified male responses to a conspecific advertisement stimulus repeatedly over three age classes in Gryllus rubens Orthoptera: The prairie mole cricket Gryllotalpa major Caracterieticas is a rare orthopteran insect of the tallgrass prairie ecosystem of the south central USA.

Altered gene-expression represents phenotypic plasticity, and many such changes appear to be evolved, adaptive responses.

There were no signs of intimate behaviors such as grooming of hosts or receipt of mouth-to-mouth feeding from hosts, which are seen in some host-specialist Myrmecophilus species among obligate host-ant species.

That is, males may use positive phonotaxis in the early stages of their adult lives, possibly to find suitable calling sites or parasitize calling males, and then later in life switch to acoustic responses in response to conspecific advertisement signals.

Diversity within populations was positively correlated with current fragment size, but not prehistoric fragment size, suggesting that the effects of increased drift following anthropogenic fragmentation are already being seen.

Exposure to exogenous enkephalins disrupts reproductive development in the Eastern lubber grasshopper, Romalea microptera Insecta: Comparing the results of the two years showed that the susceptibility of nymphs in the second year was higher than in the first year Our results support the monophyly of the genus and of one of its species groups.

Therefore, mechanical transmission of pathogens may be an important overlooking component of this grasshopper-fungal pathogen system.

In Csracteristicas, about 10 species are recognized on the basis of morphological and molecular phylogenetic frameworks.

This study not only reveals an overlooked species richness for the most popular edible insect in Mexico, but also highlights the influence of the dynamic geological and climatic history of the region in shaping its current diversity.

In gland cells, an extracellular cavity, showing region differences in the seminal receptacle and the spermathecal tube, was lined with microvillus border.
