Biology of Bemisia tabaci (Genn.) B biotype (Hemiptera, Aleyrodidae) on tomato genotypes Scientia Agricola
Oriani,Maria Auxiliadora de Godoy; Vendramim,José Djair; Vasconcelos,Cristina Jensen.
Brazil is one of the main tomato (Solanum lycopersicum) producers worldwide. Nevertheless, considerable part of the production is lost due to Bemisia tabaci (Genn.) B biotype attacks. Resistant plants can be an important method for controlling this pest in an integrated pest management. Tests for evaluating some biological aspects of B. tabaci were carried out on 18 tomato genotypes, in controlled laboratory greenhouse conditions. Thirty-day-old plants placed in plastic cages were infested with 20 whitefly pairs each, for 24 h. The development of at least 30 eggs in three leaflets per plant (repetition) was observed until adult emergence. The development period of insects grown in LA1335, PI365928 and LA722 genotypes took three days longer when compared to...

DEVELOPMENT OF Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) IN DIFFERENT STRAWBERRY CULTIVARS Rev. Bras. Frutic.
KARLEC,FÁBIO; DUARTE,ADRIANE DA FONSECA; OLIVEIRA,ANA CLÁUDIA BARNECHE DE; CUNHA,UEMERSON SILVA DA.
ABSTRACT Two-spotted spider mite, Tetranychus urticae Koch, is considered the main pest in strawberry crop. The control of this species is hampered by the low efficiency of products currently used, occurrence of populations resistant to acaricides and high reproductive potential of this pest. This leads to the use of pesticides and increased agrochemical residues in fruits. The use of resistant cultivars is considered the ideal control method because they maintain mite populations below levels of economic damage, minimize the environmental impact of pesticides at no extra cost to the farmer, and serve as an auxiliary tool in integrated pest management. In this sense, this study evaluated the resistance of strawberry cultivars to T. urticae by studying the...

Dwarf-cashew resistance to whitefly (Aleurodicus cocois) linked tomorphological and histochemical characteristics of leaves. Repositório Alice
GOIANA, E. S. S.; DIAS, N. da S.; MUNIZ, C. R.; SOARE, A. A.; ALVES, J. C.; VIDAL-NETO, F. C.; SILVA, C. S. B. D..
The cashewwhitefly (CW), Aleurodicus cocois, is an important pest of cashewin Brazil. The use of resistant plants may be an effective strategy for the control of this pest. In a preliminary assay,we found thatdwarf-cashewclones showdifferent levels of resistance to CW.Here,we hypothesized that such resistance is associated with morphological characteristics of cashew leaves and their content of phenolic compounds. We determined (i) the attractiveness and suitability for oviposition of five dwarf-cashew clones towards CW, (ii) the leaf morphology and chemistry of those clones, and (iii) the relationship between leaf characteristics and resistance to CW. In greenhouse multiple-choice assays, PRO143/7 and CCP76 showed, respectively, the lowest and highest...

Evaluación de la resistencia a Schizaphis graminum (Hemiptera: Aphididae) en cebada Rev. Soc. Entomol. Argent.
Tocho,Erica F.; Marino de Remes Lenicov,Ana M.; Castro,Ana M..
El pulgón verde de los cereales, Schizaphis graminum (Rondani), es una de las principales plagas de estos cultivos en el mundo y también presente en Argentina. Si bien el control químico es la práctica más utilizada, el uso de variedades resistentes (uno de los componentes principales del MIP) es la estrategia más efectiva y ambientalmente más amigable para el control de plagas. Dado que las plantas presentan distintos mecanismos que les permiten defenderse de los insectos, el objetivo de este trabajo fue caracterizar la resistencia a Schizaphis graminum en una población de líneas recombinantes de cebada, e identificar aquellas con mejores características, portadoras de genes de resistencia a este insecto. La antixenosis fue analizada por la prueba de...

Influence of trichomes on attractiveness and ovipositional preference of Bemisia tabaci (Genn.) B biotype (Hemiptera: Aleyrodidae) on tomato genotypes Neotropical Entomology
Oriani,Maria A de G; Vendramim,José D.
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 were evaluated in a free-choice test. Trials were set up in a randomized block design with ten replicates. Each replicate (one tomato plant per pot) was placed in a cage (80 x 50 x 50 cm) and infested with 1,000 adults during four days. Linear correlation tests were applied between the number of insects and eggs and number of trichomes in each tomato genotype. LA716, LA444-1 and PI134418 genotypes were...

Inheritance of type I glandular trichomes in Cucumis melo National Institute of Agronomic Research
Palomares-Rius, F.J.; Sarria, E.; Alba, J.M.; Gómez-Guillamón, M.L..
A high density of glandular trichomes of Type I could contribute to enhance resistance to Aphis gossypii in melon breeding programs with the Vat gene. To study the inheritance of this trait, a six-generation genetic family was obtained from the cross between the accession TGR-1551, with high density of glandular trichomes and the Spanish cultivar ‘Bola de oro’ with low trichome density. The genetic model estimated showed that the Type I trichome density followed an oligogenic inheritance with important additive effect and strong epistatic effect between heterozygous loci. The values for broad sense heritability (H2) and narrow sense heritability (h2) were 0.86 and 0.50, respectively, which made this character suitable for breeding.

No-choice ovipositional nonpreference of Bemisia tabaci (Gennadius) B biotype on tomato genotypes Scientia Agricola
Oriani,Maria Auxiliadora de Godoy; Vendramim,José Djair; Vasconcelos,Cristina Jensen.
Brazil is one of the main tomato producers worldwide. Nevertheless, 40 to 70% of the production is lost due to Bemisia tabaci (Gennadius) B biotype attacks. Resistant plant germplasm can be an important method for controlling this pest in an integrated pest management program. This research aimed to evaluate the no-choice ovipositional preference of B. tabaci B biotype on 18 tomato genotypes with different densities and types of trichomes testing two screening techniques and to determine the influence of trichomes on whitefly ovipositional preference. Two methods of confinement experiments were used. Leaflets detached from the upper third part of the tomato plants (first experiment) and 30-day-old plants (second experiment) were infested with whiteflies...

Nonpreference of the lace bug Leptopharsa heveae Drake & Poor (Heteroptera: Tingidae) for rubber tree clones Anais da SEB
Lara,Fernando M.; Tanzini,Marcel R..
To determine the resistance of rubber tree clones (Hevea brasiliensis) to Leptopharsa heveae Drake and Poor (Heteroptera: Tingidae) a trial was held in Itiquira, MT, in 1994/95 by comparing the following clones: AVROS 2037, Fx 4037, GT 1, HARBEL, IAC 207, IAN 4493, IAN 717, IAN 873, RO 38, and RO 46. Free choice and no choice trials involving preference for oviposition and feeding were carried out under field and laboratory conditions. The symptoms caused by the insects, number of excrements, number of eggs/female/leaflet, mortality rate, and number of insects/leaflet were scored. The results showed that clones Fx 4037, RO 38 and RO 46 were resistant by nonpreference for feeding and oviposition, whereas GT and IAN 873 were the most susceptible.

Oviposition preference of Bemisia tabaci (Genn.) biotype B (Homoptera: Aleyrodidae) for bean genotypes containing arcelin in the seeds Anais da SEB
Oriani,Maria A. de G.; Lara,Fernando M..
The oviposition preference of Bemisia tabaci biotype B (Homoptera: Aleyrodidae) for bean (Phaseolus vulgaris L.) genotypes containing arcelin in the seeds was evaluated. The tests were carried out under greenhouse conditions, in the dry and wet seasons, with the following genotypes: ARC 3s, ARC 5s (wild genotypes containing arcelin in the seeds); ARC 1, ARC 2, ARC 3, ARC 4 (near isogenic lines containing arcelin in the seeds - EMBRAPA) and Porrillo 70, Bolinha, IAPAR MD 808 (commercial genotypes without arcelin). In the free choice and no-choice oviposition tests, Bolinha and Porrillo 70 genotypes were preferred for oviposition by that insect. The Bolinha susceptibility could be related to the great number of acicular trichomes presents on its leaves...

Dinardo-Miranda,Leila Luci; Fracasso,Juliano Vilela; Perecin,Dilermando; Oliveira,Mariana Cecília de; Lopes,Diego Olympio Peixoto; Izeppi,Tiago Sabongi; Anjos,Ivan Antonio dos.
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. Therefore, the aim of this study was to evaluate resistance mechanisms of 12 different sugarcane cultivars to M. fimbriolata to provide information for growers for pest management. Isolated buds of each cultivar were planted in pots and kept in a greenhouse for approximately three months. The pots were then moved to climate test chambers (26 ± 1 ºC; 70 ± 10 % relative humidity; 12 h photoperiod) to carry...

Resistance of melon cultivars to Bemisia tabaci biotype B Horticultura Brasileira
Baldin,Edson LL; da Silva,José Paulo GF; Pannuti,Luiz Eduardo R.
The silverleaf whitefly, Bemisia tabaci biotype B, is currently one of the most important pests of melon, causing direct and indirect damage to plants, and significantly reducing production in the field. Due to the need for alternative methods of chemical control in melon crops, the melon cultivars AF-646, AF-682, Don Luis, Frevo, Jangada, Nilo, Vereda, Amarelo Ouro and Hales Best were assessed at field, greenhouse, and laboratory trials for resistance to whitefly B. tabaci biotype B. In general, 'Hales Best' and 'Amarelo Ouro' were the most resistant, showing oviposition non-preference against whitefly. The trichome density is associated with the variation in oviposition on the cultivars and should be further investigated in future work. These results may...
