1. Leaf consumption and oviposition of Palpita forficifera (Lepidoptera: Crambidae) on different olive cultivars
ABSTRACT The incidence of the olive caterpillar Palpita forficifera is among the main phytosanitary problems in olive groves in Brazil, and the use of resistant cultivars can be a useful tool to be incorporated into an integrated management strategy of this pest. The objective of this study was to evaluate the consumption and oviposition of P. forficifera on

2. Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis
ABSTRACT The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM)

3. Development of Oryzophagus oryzae (Costa Lima) in rice cultivars
RESUMO Cultivares resistentes a insetos são essenciais à melhoria do manejo de pragas como Oryzophagus oryzae (Coleoptera: Curculionidae), altamente prejudicial à cultura do arroz irrigado por inundação. O grau de benefício, porém, depende do tipo de resistência. Objetivou-se avaliar cultivares de arroz quanto à resistência a O. oryzae, inferindo

4. Salicylic acid: resistance inducer to two-spotted spider mite in strawberry crop
RESUMO O morangueiro é atacado por diversas pragas que ocasionam redução na produtividade. Mecanismos que repelem ou evitam que essas pragas se estabeleçam representam uma tecnologia ambientalmente correta e sustentável, para reduzir a frequência no uso de agroquímicos. Neste contexto, objetivou-se avaliar o efeito do ácido salicílico (AS) na induç

5. Antixenosis to Chrysodeixis includens (Lepidoptera: Noctuidae) among soybean genotypes
ABSTRACT The soybean looper Chrysodeixis includens is one of the main defoliating pests of soybean cultures in Brazil. This work aimed to evaluate the effect of offering different soybean genotypes to this insect to verify the occurrence of antixenosis. In a greenhouse, assays were carried out to determine the attractiveness of C. includens adults given free

6. Resistance mechanisms of sugarcane cultivars to spittlebug Mahanarva fimbriolata
ABSTRACT The spittlebug Mahanarva fimbriolata (Stål) (Hemiptera: Cercopidae) is one of the most important pests of sugarcane in Brazil. Measures for population control are currently restricted to the use of chemical insecticides and fungus Metarhizium anisopliae, in part because very little information exists regarding resistance of sugarcane cultivars.

7. Trichomes and hydrocarbons associated with the tomato plant antixenosis to the leafminer
O objetivo desse trabalho foi estudar a densidade de tricomas e os hidrocarbonetos associados à resistência por antixenose de 42 subamostras de tomateiro do Banco de Germoplasma de Hortaliças da Universidade Federal de Viçosa (BGH-UFV) a Liriomyza trifolii. Essas subamostras foram estudadas e a cultivar 'Santa Clara' que foi utilizada como padrão de sus

8. Antibiosis and antixenosis of six commonly produced potato cultivars to the green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae)
The antibiotic and antixenotic resistance of six commonly produced potato cultivars in Iran including Aozonia, Agria, Cosima, Cosmos, Kondor and Savalan to the green peach aphid, Myzus persicae Sulzer, were investigated under laboratory conditions at 20 ± 2ºC, 65 ± 5% RH and 16:8h (L:D) in 2009. Antibiosis experiments showed significant differences in the

9. Resistência de cultivares de batata a Myzus persicae (Sulz.)(Hemiptera: Aphididae)
Aphids are the most important vectors of viruses infecting potato (Solanum tuberosum). We focused on the response of the aphid vector Myzus persicae (Sulzer) to five commercial potatocultivars: Ágata, Jaette Bintje, Mondial, Monalisa and Santè, by traditional antibiosis and antixenosis tests and by the EPG (Electrical Penetration Graph) technique, as a ste

10. Influence of trichomes on attractiveness and ovipositional preference of Bemisia tabaci (Genn.) B biotype (Hemiptera: Aleyrodidae) on tomato genotypes
Brazil is one of the world's largest tomato producer, but considerable part of the production is lost due to the attack of Bemisia tabaci (Genn.) B biotype. Resistant germoplasm plants can be an important method for B. tabaci control in integrated pest management approaches. The attractiveness and ovipositional preference of B. tabaci for 17 tomato genotypes

11. Inheritance of antixenosis resistance of Lycopersicon pennellii (LA 716) and L. hisrsutum f. typicum (LA 1777) to Tuta absoluta / Herança da resistência por antixenose de Lycopersicon pennellii (LA 716) e L. hisrsutum f. typicum (LA 1777) a Tuta absoluta
Com o objetivo de estudar a herança de caracteres de resistência do tipo antixenose à traça-do-tomateiro, foram avaliadas populações F2 e de retrocruzamento, bem como gerações parentais, em cruzamentos interespecíficos envolvendo L. esculentum cv. Santa Clara x L. pennellii (LA 716) e L. esculentum cv.IPA-5 x L. hirsutum f. Typicum (LA 1777). Os car

12. Aphid Resistance in Medicago truncatula Involves Antixenosis and Phloem-Specific, Inducible Antibiosis, and Maps to a Single Locus Flanked by NBS-LRR Resistance Gene Analogs1
Aphids and related insects feed from a single cell type in plants: the phloem sieve element. Genetic resistance to Acyrthosiphon kondoi Shinji (bluegreen aphid or blue alfalfa aphid) has been identified in Medicago truncatula Gaert. (barrel medic) and backcrossed into susceptible cultivars. The status of M. truncatula as a model legume allows an in-depth stu
