Observé que colonias de hormigas cosechadoras occidentales (Pogonomyrmex occidentalis), marcadas entre 1977 y 1994, sobrevivieron una media 15.65 años (n = 112). La colonia vivió más tiempo sobrevivió 42 años.

Frankliniella occidentalis is a highly destructive and invasive agricultural pest that has developed resistance to variety of insecticide classes. Different planting structures use frequency can directly affect the development F. occidentalis. In this study, susceptibility three field strains occidentalis, collected over one year (April November) from habitat conditions (facility agriculture ar...

The parasitofauna of amphibians from the province San Juan has been studied very little. In particular, only one helminthological study reported on Odontophrynus occidentalis (Berg, 1896). aim present was to describe endoparasites O. occidentalis, including protozoa and nematodes. Twenty-one adults (13 males 8 females) were analysed for parasites. Collected parasites examined using standard par...

Genetic diversity in mtDNA was assessed within the unisexual (all female) hybridogenetic fish Poeciliopsis monacha-occidentalis and the two sexual species from which it arose. Results confirm that P. monacha was the maternal ancestor and that paternal leakage of P. occidentalis mtDNA has not occurred. Of particular interest is the high level of de novo mutational divergence within one hybridoge...

The full-length sequence of a new isolate of Apple chlorotic leaf spot virus (ACLSV) from Korea was divergent, but most closely related to the Japanese isolate A4, at 84% nucleotide identity. The full-length cDNA of the Korean isolate of ACLSV was cloned into a binary vector downstream of the bacteriophage T7 RNA promoter and the Cauliflower mosaic virus 35S promoter. Chenopodium quinoa was suc...

The effect of six various pesticides on the growth of yeasts isolated from agricultural soil was investigated. Two herbicides (with the effective substances lactofen and metazachlor), two fungicides (with the effective substances fluquinconazole and prochloraz), and two insecticides (with the effective substances cypermethrin + chlorpyrifos and triazamate) were tested. It is evident that there ...

Some biochemical, haematological and histological responses were studied in rats undergoing a long term feeding with a Telfairia occidentalis-supplemented diet. Biochemical and hematological parameters investigated included serum protein, total cholesterol, lipid peroxidation, haemoglobin, white blood cells, Aspartate aminotransferase, Alanine aminotransferase, Alkaline phosphatase, Glutathione...
