The sweetpotato whitefly Bemisia tabaci Q species is a recent invader and important pest of agricultural crops in China. This research tested the hypothesis that the Q populations that establish in agricultural fields in northern China each year are derived from multiple secondary introductions and/or local populations that overwinter in greenhouses (the pest cannot survive winters in the field...

Increasing global human population and per-capita food consumption are expected to exacerbate the already massive agricultural footprint in tropical ecosystems. Madagascar is home to exceptional levels of biodiversity and is in the midst of severe land-use change, mostly driven by slash-and-burn, smallholder agriculture. Understanding the consequences of these agricultural practices for Malagas...

This paper aims to analyze tariff protection policies in the agricultural sector of developing countries. The agricultural tariff structure in developing countries is characterized by: i) high average tariffs, ii) the existence of tariff escalation, iii) dispersion of nominal tariffs across tariff lines, and iv) a wide gap between average nominal tariffs and import-weighted average tariffs.

UNLABELLED The integration-based genome database provides useful information through a user-friendly web interface that allows analysis of comparative genome for agricultural plants. We have concentrated on the functional bioinformatics of major agricultural resources, such as rice, Chinese cabbage, rice mutant lines, and microorganisms. The major functions are focused on functional genome anal...
