Effect of five soybean cultivars (Sahar, JK, BP, Williams, and L17) on life table parameters of the beet armyworm Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) was evaluated at 25±1∘C, 60±5% relative humidity and a photoperiod of 16 h light/8 h dark. The highest and lowest net fecundity rates were obtained on Williams (244.1±19.4 eggs/female) and L17 (80.5±6.9 eggs/female...
Litopous baehri gen. et sp. nov. and Scaphinion clavatus gen. et sp. nov. are described. New combinations (previous genus in parentheses) are Aethyssius minor (Carter) (Tanychilus Newman), Homotrysis subopaca (Carter) (Metistete Pascoe), Metistete armata Carter (Homotrysis Pascoe), M. opaca (Carter) (Tanychilus), M. punctata (Carter) (Melaps Carter), and Nocar subfasciatus Carter...
The numbers of Cybister tripunctatus orientalis Gschwendtner diving beetles are declining in most regions of Japan, and it is included in the Red Data List of species in 34 of 47 prefectures of Japan. However, basic ecological information about C. tripunctatus orientalis, such as its feeding habits, remains unknown. In order to elucidate the feeding habits of C. tripunctatus...
The grass-cutting ant Atta bisphaerica is one of the most serious pests in several pastures and crops in Brazil. Fungal diseases are a constant threat to these large societies composed of millions of closely related individuals. We investigated the occurrence of filamentous fungi associated with the ant A. bisphaerica in a pasture area of Viçosa, Minas Gerais State, Brazil...
A new fossil genus, Electropteron gen.n., and a new species, E. avus sp.n., are described from the Dominican Amber. Electropteron avus gen.n., sp.n., appears to be related to some of the extant Great Antillean lycids and is the first fossil taxon from the subfamily Leptolycinae.
Four colonies of the ant Pachycondyla striata were used to analyze the specie behavioral repertoire. Forty-six behavioral acts were recorded in laboratory. Here, we present the record the division of labor between the castes and the temporal polyethism of monomorphic workers. The queens carried out many of the behavioral traits recorded in this work however; they performed them...
The rarely collected ant Lenomyrmex inusitatus Fernández 2001 is recorded for the first time in Ecuador. The queen is described. The new record is the southernmost limit of distribution for the genus. A key to the workers of the six Lenomyrmex species and a key for the known queens are provided.
The distribution patterns of Orthoptera are described for the boreal zone. The boreal fauna of Eurasia includes more than 81 species. Many of them are widely distributed. The monotypic genus Paracyphoderris Storozhenko and at least 13 species are endemics or subendemics. About 50 species are known from boreal North America. Four endemic species are distributed very locally...
Life tables were established for trichlorphon-resistant and susceptible Bactrocera dorsalis strains based on the laboratory observations. Trichlorphon-resistant B. dorsalis strain had longer pupal and preoviposition periods, and mean generation time compared to the trichlorphon susceptible strain. Lower fecundity, emergence rate, and probability of standard fecundity ??, and...
In order to adopt correct conservation strike plans to maintain bee pollination activity it is necessary to know the species
We studied the morphology of the ovipositor of Platygaster diplosisae (Hymenoptera: Platygasteridae) and Aprostocetus procerae (= Tetrastichus pachydiplosisae) (Hymenoptera: Eulophidae), two parasitoids associated with the African rice gall midge (AFRGM), and Orseolia oryzivora (Diptera: Cecidomyiidae). Scanning electron microscope techniques were used for this study. The...
Succession patterns of adult blow flies (Diptera: Calliphoridae) on decaying alligators were investigated in Mobile (Ala, USA) during August 2002. The most abundant blow fly species visiting the carcasses were Chrysomya rufifacies (Macquart), Cochliomyia macellaria (Fabricus), Chrysomya megacephala (Fabricus), Phormia regina (Meigen), and Lucilia coeruleiviridis (Macquart...
