“…In the other cultivars tested, survival varied from 52.8 to 30.5%. the presence of glandular and non-glandular trichomes may have influenced the survival of the spider mite, either by exudation of adhesive substances that limit displacement or by the toxic effect on mites, as observed by other studies (LUCZYNSKI et al, 1990;STEINITE;EVINSH, 2003;GONÇALVES et al, 2006;FIGUEIREDO et al, 2010). however, Kishaba et al (1972) observed that non-glandular trichomes were favorable to T. urticae infestations on strawberry leaves.…”

-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 development of its biological aspects. comparative biology experiments and non-preference tests for feeding and oviposition for spider mite were carried out in 16 strawberry cultivars under laboratory conditions. Based on results, it was found that camarosa, Florida Festival, IAc campinas and Sabrosa strawberry cultivars indicated the possibility of antibiosis type resistance to spider mite, influencing the preference to food, development and oviposition, indicating the existence of differentiated reaction in population development among cultivars. Index terms: two-spotted spider mite, comparative biology, antixenosis. DESENVOLVIMENTO DE Tetranychus urticae KOCH (ACARI: TETRANYCHIDAE) EM DIFRENTES CULTIVARES DE MORANGUEIRORESUMO -O ácaro-rajado, Tetranychus urticae Koch, é considerado a principal praga da cultura do morangueiro. O controle desta espécie é dificultado pela baixa eficiência dos produtos atualmente empregados, pela ocorrência de populações resistentes a acaricidas e ao alto potencial reprodutivo dessa praga. Isso induz ao uso de agrotóxicos e ao aumento de resíduos de agroquímicos na fruta. O emprego de cultivares resistentes é um método de controle considerado ideal, pois permite a manutenção do ácaro em níveis inferiores aos de dano econômico, minimiza o impacto ambiental dos agrotóxicos, sem ônus adicional ao agricultor, e serve como ferramenta auxiliar no manejo integrado da praga. Nesse sentido, o trabalho avaliou a resistência de cultivares de morangueiro a T. urticae através do estudo do desenvolvimento de seus aspectos biológicos. Experimentos de biologia comparada, testes de não preferência à alimentação e a oviposição para o ácaro-rajado foram conduzidos em 16 cultivares de morangueiro em condições de laboratório. A partir dos estudos, constatou-se que as cultivares camarosa, Florida Festival, IAc campinas e Sabrosa indicaram a possibilidade da existência de resistência do tipo antibiose para o ácaro-rajado, influenciando na preferência à alimentação, desenvolvimento e oviposição, indicando a existência de reação diferenciada entre as cultivares estudadas. Termos para indexação: ácaro-rajado, biologia comparada, antixenose.

“…Negative effect of glandular and non-glandular (tector) trichomes on strawberry leaves on oviposition and survivorship of the two-spotted spider mite was reported by Luczynski, Isman, Raworth, and Chan (1990). However, in an extensive field evaluation of 29 strawberry genotypes, Kishaba, Voth, Howland, Bringhurst, and Toba (1972) observed higher susceptibility to two-spotted spider mite by genotypes with denser pubescence.…”

The two-spotted spider mite, Tetranychus urticae Koch, is one of the main strawberry pests in Brazil and many other countries. The objective of this study was to compare the resistance of eight strawberry genotypes ('Albion', 'IAC Guarani', 'IAC Princesa Isabel', 'Oso Grande', IAC T-0104, IAC 12, IAC 4 and IAC 1.13) to the two-spotted spider mite, by assessing injury level, biological parameters and host preference of the mite. To facilitate the interpretation of the results, leaf trichomes of each genotype were quantified. Thirty days after the artificial infestation of the genotypes with the mite, IAC T-0104, IAC 12 and 'IAC Princesa Isabel' showed the lowest injury levels. 'IAC Princesa Isabel', IAC 4 and IAC T-0104 were distinguished from other genotypes by the highest mean generation time (T) of the mite, while 'IAC Guarani' was distinguished by the lowest T value. Significantly lower values of intrinsic rate of increase (r m ), finite rate of increase (λ) and net reproductive rate (R o ) were determined on 'IAC Princesa Isabel' and IAC 1.13. The mite showed preference for 'IAC Guarani', as inferred by the larger number of females when offered the chance to select the detached host leaflets. Trichome density was highest on IAC 1.13 and lowest on IAC T-0104, IAC 12, 'Albion' and 'Oso Grande'. The results suggested that 'IAC Princesa Isabel', IAC T-0104 and IAC 12 are resistant, IAC 4 and IAC 1.13 are moderately resistant, and 'IAC Guarani', 'Oso Grande' and 'Albion' are susceptible to the mite.

“…It is well accepted that leaf nitrogen and phosphorus can enhance growth and fecundity of herbivorous arthropods (Mattson 1980;White 1993;Schoonhoven et al 1998;Perkins et al 2004), and that leaf phenolics are defensive substances against spider mites (Larson and Berry 1984) as well as many arthropod herbivores (Feeny 1970;Bryant et al 1987;Luczynski et al 1990). In this study, the previously damaged plants with Gi.…”

Arbuscular mycorrhizal fungi species‐specifically affect induced plant responses to a spider mite

It is widely recognized that arbuscular mycorrhizal fungi (AMF) improve plant growth and nutrient conditions, but their effects can vary from negative to positive depending on AMF species. Since the performance of herbivorous arthropods varies with plant quality, different AMF species should differently affect the density of herbivorous arthropods on plants and the herbivoreinduced plant responses. We examined the indirect effects of AMF on the number of spider mites (Tetranychus urticae) and the number of damaged leaves in an outdoor glass-chamber experiment, using Lotus japonicus plants inoculated with one of four different AMF species (Gigaspora margarita, Glomus etunicatum, Gl. intraradices, and Acaulospora longula). Plants with Gi. margarita and A. longula had significantly fewer female mites than plants with Gl. etunicatum and Gl. intraradices, and plants with Gi. margarita had the fewest damaged leaves, followed by plants with A. longula, Gl. intraradices, and Gl. etunicatum. To examine species-specific effects of AMF on herbivore-induced plant responses, we carried out a bioassay with eggs laid by spider mites, and analyses of leaf chemicals (carbon, nitrogen, phosphorus, and total phenolics) using plants subjected or not subjected to herbivory. The bioassay showed that mite egg production and its changes following mite herbivory changed depending on the AMF species. In addition, Principal component analysis for leaf chemicals revealed not only mite-induced changes in leaf chemical composition, but also AMF effects on the herbivore-induced response in a speciesspecific way. Thus, we need to pay more attention to the species identity of AMF as an important factor in determining the strength of effects of belowground AMF on the performance and/or preferences of aboveground herbivores.
