Repellency of Wild Oregano Plant Volatiles, Plectranthus Amboinicus, and Their Essential Oils to the Silverleaf Whitefly, Bemisia Tabaci, on Tomato.

The Bemisia tabaci (Gennadius) whitefly is a major economically damaging pest of many crops such as tomato (Solanum lycopersicum L.). Pesticides are widely used to control B.

Agroecosystem diversification with legumes or non-legumes improves differently soil fertility according to soil type.

Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation.

First Report of Bacterial Wilt Caused by on in Martinique.

, commonly known as Gwo ten in the French West Indies (Martinique), is a semi-succulent perennial plant of the Lamiaceae family. This aromatic plant wich is widespread naturally throughout the tropics is of economic importance because of the therapeutic and nutritional properties attributed to its natural phytochemical compounds wich are highly valued in the pharmaceutical industry. In March 2019, wilted plants intercropped with tomato plants (cv.

Comparison of the Flavonoid Profiles of Corn Silks to Select Efficient Varieties as Trap Plants for .

In Martinique, is a common pest of tomato and is responsible for significant economic losses. To fight against proliferation and damage, corn could be used as a trap crop since larvae growth in the corn silk was inhibited by the presence of some flavonoids. However, only some corn varieties show an efficient inhibitory activity against depending on their flavonoid composition.
