Cotton bollworm, Helicoverpa armigera (Hübner), is a major pest of tomato (Lycopersicon esculentum) in Australia. Host-plant resistance may prove an alternative to current control methods. The role of entrapment in glandular-trichome-induced mortality of

Setting acceptable seed viability thresholds for the World Vegetable Genebank collections
Abstract A genebank aims to conserve and distribute genetic diversity by keeping germplasm alive. For seed genebanks, this means that monitoring the viability of seed lots is a core activity. An initial assessment of seed lot viability—usually through a germination test—is used to decide whether or not a seed lot should be put into genebank storage ...

ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

ABSTRACT Soil nutrient transformation capacity is a critical determinant of sustainable productivity in perennial cropping systems; however, the extent to which high‐yielding crops actively regulate rhizosphere microbial assembly to maintain nutrient availability remains poorly understood.

Agrosuppression: A Bioassay for the Hypersensitive Response Suited to High-Throughput Screening
We describe a novel method, agrosuppression, that addresses the need for an assay of the hypersensitive response (HR) in intact plants that is rapid and adapted to high-throughput functional screening of plant and pathogen genes.

Development of Bemisia tabaci (Gennadius,1889) biotype B on Lycopersicon spp. genotypes
Whiteflies are phytophagous insects, whose nymphs and adults suck the phloem sap, causing direct damage due to host plant weakness. In tomato (Lycopersicon spp.) crops, they are important vectors of limiting fitoviruses.

Nonpreference of whitefly for oviposition in tomato genotypes
The silverleaf whitefly is one of most important pests of tomato (Lycopersicon spp.). The use of host plant resistance to control this insect is an interesting, potentially useful technique, but in demand of more research.
