“…Na defesa induzida, a planta expressa resistência contra o herbívoro somente após a injuria, podendo atuar diretamente sobre os herbívoros ou inimigos naturais (Thaler et al 1999). O morangueiro Fragaria x ananassa possui mecanismo de defesa constitutivo e induzido ao ataque do ácaro rajado Tetranychus urticae Koch (Karban & Baldwin 1997, Steinite & Ievinsh 2002.…”

Existe a hipótese de que plantas que sofreram infestações prévias por T. urticae são capazes de responder às injúrias com maior rapidez em comparação àquelas que não foram atacadas (Balwin & Schmelz 1996).…”

-Plants of strawberry Fragaria x ananassa may present mechanisms of direct and indirect defenses against herbivores. Such defenses may influence behaviour and development of phythophagous mites and their natural enemies, thereby reducing herbivory rate. We tested the effect of pre-infestation of strawberry plants by Tetranychus urticae Koch on the development and reproduction of the mite species. Strawberry plants (cultivar IAC Campinas) were divided into two groups: plants without and plants with pre-infestation of T. urticae. The length of immature phases, the number of eggs per female and the survival of mites were not altered by the pre-infestation. These results may be associated to either the absence or low level of induced resistance of the cultivar IAC Campinas or perhaps the pre-infestation was insufficient to induce defenses. The reported resistance of this cultivar to T. urticae could be related to indirect defenses.KEY WORDS: Fragaria x ananassa, two spotted spider mite, induced resistance RESUMO -Plantas de morangueiro Fragaria x ananassa podem apresentar mecanismos de defesa direta e indireta contra herbívoros. Tais defesas podem alterar o comportamento e o desenvolvimento dos ácaros fitófagos e seus inimigos naturais, reduzindo a taxa de herbivoria. Testou-se o efeito da pré-infestação de plantas de morangueiro por Tetranychus urticae Koch sobre o seu desenvolvimento e reprodução. Plantas de morangueiro cultivar IAC Campinas foram divididas em dois grupos: plantas limpas e plantas pré-infestadas por T. urticae. A infestação prévia de plantas de morangueiro por T. urticae não alterou a duração das fases imaturas, a fecundidade e a sobrevivência das fêmeas do ácaro. Tais resultados podem estar associados à inexistência ou baixo nível de resistência induzida da cultivar IAC Campinas, ou ainda, ao fato de a pré-infestação ter sido insuficiente para induzir defesa. Assim, a resistência relatada na cultivar IAC Campinas a T. urticae pode estar relacionada às defesas indiretas.

“…Varietal resistance can be evaluated through the evaluation of factors such as mite behavior, level of inflicted plant injury (Petrova, Cudare, Steinite, & Laugale, 2000;Wold & Hutchison, 2003), developmental time, survivorship, fecundity, oviposition rate and life table parameters (Gugole Ottaviano, Sánchez, Roggiero, & Greco, 2013;González-Domínguez et al, 2015). Factors related to resistance to mite pests include morphological characteristics such as tissue thickness and density of trichomes (Handley, Ekbom, & Agren, 2005;Oku, Yano, & Takafuji, 2006;González-Domínguez et al, 2015), as well as the production of defense compounds, which often inhibit mite feeding (Steinite & Ievinsh, 2002;Figueiredo, Resende, Morales, Gonçalves, & Da Silva, 2013). The aim of this study was to compare the resistance of eight strawberry genotypes to the two-spotted spider mite, by assessing injury level, biological parameters and host preference.…”

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.

“…Strawberry resistance to two-spotted spider mite is genetically determined, as various cultivars exhibit different degrees of infestation, both in controlled and field conditions (Shanks et al, 1995;. More resistant strawberry varieties have been shown to contain higher inducible activity of oxidative enzymes (Steinite and Ievinsh, 2002), possibly located in glandular trichomes of leaves (Steinite and Ievinsh, 2003 The aim of the present study was to determine the seasonal pattern of two-spotted spider mite Tetranychus urticae on strawberries cultivated in polythene-covered high tunnels in temperate climatic conditions. Various cultivars were used and the effect of modification of plant covering indices on abundance and incidence of these mites was also tested.…”

The aim of the present study was to determine the seasonal pattern of two-spotted spider mite Tetranychus urticae on strawberries cultivated in polythene-covered high tunnels in temperate climatic conditions. Various cultivars were used and the effect of modification of plant covering indices on abundance and incidence of these mites was also tested. The number of two-spotted spider mites was relatively low at the beginning of the vegetation season and started to increase when average air temperature rose above 20 to 25 °C. In the experiment two types of tunnels differing in additional plant cover were used. The maximum mite abundance did not significantly vary between varieties in tunnel 1 conditions, but it was significantly lower for variety 'Sonata' in tunnel 2 conditions. Mite numbers significantly declined after strawberry foliage mowing and removal of polythene cover. Mite development was prolonged in tunnel 1, where additional cover of plants was used and higher early season air temperature was recorded in comparison to tunnel 2. It was concluded that increase in early season temperature can increase two-spotted spider mite abundance and have a more negative effect on strawberry plants in respect of foliage damage by mites.
