1. A unified ratio-dependent supply-demand driven tritrophic model of the cassava (Manihot esculenta Crantz) system was compared to field data, and then used to explore the basis for the successful control of cassava mealybug (CM, Phenacoccus manihoti Mat.-Ferr.) in Africa by the exotic parasitoi...

A field trial was conducted to investigate the efficacy of an oil formulation of the fungal entomopathogen, Metarhizium flavoviride, for control of the variegated grasshopper, Zonocerus variegatus. The results of the trial showed a significant reduction in grasshopper populations following spray ...

How the pathogen inoculum size affects the pathogenicity of Neozygites floridanatoMononychellus tanajoawas studied at 28°C, 12L:12D photoperiod and 90–100% RH. All inoculum sizes tested (one, two, four, six, and eight capilliconidia per mite) were lethal. Dead mites started to appear 48 hr after ...

The occurrence of P. tritici-repentis among the fungal flora of soft white winter wheat seed in New York, USA, was assessed during 1990-91. The fungus was recovered from 54% of the seed lots in 1990 and from 36% of the seed lots in 1991, infecting an av. of 2.1 and 0.6% of the seeds, respectively...

Polymerase chain reaction (PCR)-based applications in plant molecular biology and molecular diagnostics for plant pathogens require good quality DNA for reliable and reproducible results. Leaf tissue is often the choice for DNA extraction, but the use of other sources such as tubers, stems, or se...

The application of biotechnology tools has made it possible to make significant advances in the detection of pathogens and in the study of the genetic variability of pathogen populations. As a result, adequate disease management strategies can be planned, and disease resistance markers for plants...

Risk assessments related to use of water and safety of fresh produce originate from both water and food microbiology studies. Although the set-up and methodology of risk assessment in these 2 disciplines may differ, analysis of the current literature reveals some common outcomes. Most of these st...

Red leaf blotch, caused by Dactuliochaeta glycines (R.B. Stewart) Hartman & Sinclair (2) (= Pyrenochaeta glycines R.B. Stewart), was observed on soybeans (Glycine max (L.) Merr.) at Bukuru, near Jos in the state of Plateau, Nigeria, in 1990. Over 80% of the plants in the 4¬ha nonirrigated, sandy ...
