Introgressions of Lycopersicon pennellii improve growth and development of greenhouse tomatoes

open access: gold, 2005
This thesis focused on the possibilities to improve greenhouse tomato (Lycopersicon esculentum cv. Moneymaker) in terms of yield. The domestic tomato has a very narrow genetic base which makes breeding for better performance a difficult task. The wild, crossable relatives of tomato present the possibility to introduce more variation in the gene pool of

Resistance of tomato genotypes with high level of acylsugars to Tetranychus evansi Baker & Pritchard Resistência de genótipos de tomateiro com alto teor de acilaçúcares a Tetranychus evansi Baker & Pritchard

open access: yesScientia Agricola, 2008
The Lycopersicon pennellii accession LA716 has been used as a source of arthropod pest resistance in tomato breeding programs due the high contents of acylsugars presents in its leaflets.

Entrapment of two-spotted spider mite, Tetranychus urticae (Acari: Prostigmata: Tetranychidae), by type IV glandular trichomes of Lycopersicon species [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران, 2012
Two-spotted spider mite (TSSM) is becoming resistant to many of the pesticides used in the tomatofields. A potential alternative method of control is host plant resistance, which may be mediated byglandular trichomes.

Development of Bemisia tabaci (Gennadius,1889) biotype B on Lycopersicon spp. genotypes

open access: yesScientia Agricola, 2002
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.
