This study represents the first complete modern account of the Sphingidae of Pakistan and takes the form of an annotated checklist, based on several national collections and those of a number of individuals. Of the 60 species and subspecies found, 14 are new records to the fauna of Pakistan, namely Agnosia orneus, Langia zenzeroides subsp. zenzeroides, Polyptychus trilineatus subsp. trilineatus...

A new species of eriophyid mite, Leipothrix dipsacivagus n. sp. (Acari: Prostigmata: Eriophyidae), collected fromDipsacus laciniatusL. (Dipsacaceae) andDipsacus fullonumL. in Serbia, Bulgaria, andFrance, is described and illustrated.Differential diagnosis is provided in comparisonwith Leipothrix knautiae (Liro)n. comb., andLeipothrix succisae (Roivainen)n. comb., two species that also are propo...

Interpopulational gene flow within a species can reduce population differentiation due to genetic drift, whereas genetic exchange among taxa can impede speciation. We used allozyme data to estimate gene flow within and among geographic races and species of perennial herbs in the Ipomopsis aggregata complex (Polemoniaceae). Estimates of interpopulational gene flow within taxa from two methods (F...

Four Lentinula edodes strains (Le10, 46, K2, Assai) were assessed for their antagonistic effect on four filamentous fungus species of agricultural importance (Helminthosporium euphorbiae, Helminthosporium sp, Fusarium solani and Phomopsis sojae) and on Alagoas serotype of Vesicular Stomatitis Virus (VSA). The L. edodes strains studied had variable effects on the filamentous fungi and on VSA. Th...

The nutrition and metabolism of aphids are of interest to biochemists, since these important pests depend upon leaf cell sap for their nutrition and excrete large amounts of carbohydrate and amino acids (1, 2). This suggests that they may have some special nutritional requirements (3), and that their carbohydrate metabolism may possess unusual features. The evidence obtained to date indicates t...
