Post-Emergence Development of Male Genitalia in Schistocerca Americana
Copyright by Hojun Song 2002 ABSTRACT Post-emergence development of male genitalia in Schistocerca americana (Orthoptera: Acrididae: Cyrtacanthacridinae) was studied. The present study demonstrates for the first time that the internal skeletal structures in the male genitalia continue to develop after the adult emergence. Also, the taxonomic use of the genitalic characters is reevaluated. An experiment was set up to examine the developmental patterns in the male genitalia and female ovipositor. The mechanism of the genitalic apodeme development is explained by the resilin deposition possibly affected by bursicon secretion. Overall, the structures affected by the cuticle deposition are the apodemes providing muscle attachment sites that enable the necessary movement during copulation. Non-changing structures in the genitalia may be directly involved in the internal courtship during copulation. Therefore, sexually immature individuals can be considered functionally incapable of copulation because the necessary structures have not been fully matured. In order to test if the post-emergence development is widespread, the different aged specimens of Schistocerca gregaria (Forskål) and Locusta migratoria (Linnaeus) were studied. Although the morphology was different between Schistocerca and Locusta, the overall developmental patterns were similar. The sexual maturation period of Schistocerca takes at least 30 days after the emergence. The life history theory predicts that the age at maturity is shaped by the trade-off between survival and reproduction. In Schistocerca, the structures associated with the flight mature earlier in adult development whereas the genitalia continue to develop for about thirty days after emergence. Delayed maturation is well explained by the life history theory when considering that the flight may be the most important trait for survival and that the reproduction is usually costly. -

The state of Amapá is one of the Amazonian states with a large knowledge gap regarding invertebrate biodiversity. Also, there is no record in the literature of systematic studies that focus mainly on the Acridofauna. Therefore the goal of this study was to understand the diversity and abundance of grasshoppers (Gomphocerinae) of the Environmental Protection Area of the Curiaú river, Macapá - AP. Twelve samples were collected from October 2011 to September 2012 using the active search technique with sweep nets. A total of 508 Gomphocerinae individuals were sampled and classified into five genera and twelve species. The floristic composition of sites A1 and A3, and sites A5 and A6, are considered more similar since the locusts are closely related to the vegetation. -

Effect of Two Dosages of Metarhizium Anisopliae Var. Acridum Against Rhammatocerus Schistocercoides Rehn(1)
Effect of two dosages of Metarhizium anisopliae var. acridum 1531 Effect of two dosages of Metarhizium anisopliae var. acridum against Rhammatocerus schistocercoides Rehn(1) Marcos Rodrigues de Faria(2), Bonifácio Peixoto Magalhães(2), Roberto Teixeira Alves(3), Francisco Guilherme Vergolino Schmidt(2), João Batista Tavares da Silva(2) and Heloísa Frazão(2) Abstract – The fungus Metarhizium anisopliae var. acridum, strain CG 423, was tested under field conditions against the gregarious grasshopper Rhammatocerus schistocercoides (Rehn) (Orthoptera: Acrididae). Conidia formulated in a racemic mixture of soybean oil and kerosene were sprayed under field conditions using an ultralow-volume hand-held atomizer Ulva Plus adjusted to deliver 2.9 L/ha. Bands composed of 2nd instar nymphs were treated with either 5.0x1012 or 1.0x1013 viable conidia/ha. The number of insects in each band was estimated at day one following spraying and by the end of the field trial (15 to 16 days post- treatment). Reductions in population size reached, in average, 65.8% and 80.4% for bands treated with the higher and lower dosage, respectively. For both dosages, total mortality rates of insects collected at two days post-application, and kept in cages for 14 days under lab conditions, showed no significant differences as compared to that obtained with insects collected immediately after spraying. Healthy insects were fed to native grasses sprayed on the field with 1.0x1013 viable conidia/ha. Mortality levels of the nymphs fed on grasses collected two and four days post-application were not affected when compared to nymphs fed on grasses collected immediately following application. -

This article is published with open access Abstract The green–brown polymorphism of grasshoppers and bush-crickets represents one of the most penetrant polymorphisms in any group of organisms. This poses the question of why the polymorphism is shared across species and how it is maintained. There is mixed evidence for whether and in which species it is environmentally or genetically determined in Orthoptera. We report breeding experiments with the steppe grasshopper Chorthippus dorsatus, a polymorphic species for the presence and distribution of green body parts. Morph ratios did not differ between sexes, and we find no evidence that the rearing environment (crowding and habitat complexity) affected the polymorphism. However, we find strong evidence for genetic determination for the presence/absence of green and its distribution. Results are most parsimoniously explained by three fl 1234567890();,: 1234567890();,: autosomal loci with two alleles each and simple dominance effects: one locus in uencing the ability to show green color, with a dominant allele for green; a locus with a recessive allele suppressing green on the dorsal side; and a locus with a recessive allele suppressing green on the lateral side. Our results contribute to the emerging contrast between the simple genetic inheritance of green–brown polymorphisms in the subfamily Gomphocerinae and environmental determination in other subfamilies of grasshoppers. -
