Eye colour of Triatoma infestans is controlled at a single autosomal locus, with black-eye as the dominant gene and red-eye as the recessive. Inheritance of these characters follows a classical Mendelian system, enabling eye colour to be used as a marker for studies of mating frequency. We found no significant differences in oviposition rates and egg hatching rates irrespective of parental phen...

The reliability of morphological characters and host differential plants for distinguishing between two populations of Meloidogyne incognita was studied. Population A (originally from North Carolina) had incognita-type perineal patterns. A single egg mass subpopulation of population A had a mixture of incognita and acrita perineal patterns with 33% of the patterns atypical for either species. P...

Siddha is a traditional medical system of India. According to siddha system of medicine, chendooram is a red colour powder generally made of metallic compounds. Mercury is used in the form of rasa chendooram (red oxide of mercury). This paper deals with the standardization of Kantha chendooram. It is a Siddha preparation of 8 ingredients, viz. 1. Purified Lode Stone, 2. Purified Sulphur, 3. Lea...

Quails are blessed with several desirable characters like fast growth, early sexual maturity, high rate of egg production, short generation interval, requirement of less floor space, short incubation period and less susceptibility to diseases. Generally quails are reared in multi-tier cages both during growing and laying periods. The convenience in handling and conservation of space and energy ...

The nonadult stages, egg strings, eggs, larvae, and cysts of Gordius robustus, Paragordius varius, and Chordodes morgani are described morphometrically. The goal was to document the differences between species and to evaluate the usefulness of morphometrics in species identification. In concert, multivariate analysis of variance (MANOVA) and univariate analysis of variance (ANOVA, a posteriori ...

The origin and evolution of clitellate annelids--earthworms, leeches and their relatives--is poorly understood, partly because body fossils of these delicate organisms are exceedingly rare. The distinctive egg cases (cocoons) of Clitellata, however, are relatively common in the fossil record, although their potential for phylogenetic studies has remained largely unexplored. Here, we report the ...

BACKGROUND The flower bug Orius sauteri is an important polyphagous predator that is widely used for the biological control of mites and aphids. However, the optimal conditions for mass rearing of this insect are still unclear, thus limiting its application. METHODOLOGY In this study, we investigated the optimal ingredients of an artificial diet for raising O. sauteri using a microencapsulati...

HE origin, fertility, and identifying vegetative characteristics associated with some monosomics of Upland cotton, Gossypium hirsutum L., have been described by BROWN and ENDRIZZI (1963). The monosomes were highly stable and n-1 gametes were transmitted with a high frequency through the egg, but very rarely through the pollen. ENDRIZZI and BROWN (1963) have obtained the cytogenetic data that id...

The Sejoidea currently contains three families (Sejidae, Ichthyostomatogasteridae, Uropodellidae) of enigmatic mesostigmatic mites with a mixture of characters of general distribution in the Parasitiformes (e.g., hypertrichy, tarsus IV with an intercalary sclerite bearing a pair of ventral setae, archispermous mating system) and derived character states both unique (e.g., distinctive female ste...
