“…The Ro parameter has a direct influence on the intrinsic increase rate (rm), which probably led rm to present the same variation trends among cultivars as for Ro. The rm, Td and λ values observed in this work also presented variations, as evidenced by other authors (SILVA et al, 1985, KASAP, 2004MORO et al, 2012), thus showing intra-specific and interspecific variations in the mite development relative to its host (species or cultivar).…”

-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.

“…However, differences were much smaller for mites maintained on A. merrillii than on other plant species, referring only to durations of egg and larval stages; for protonymphs and deutonymphs, no significant differences were observed between durations on coconut and A. merrillii. A few other studies have reported differences in egg incubation period when mites were reared on different substrates (Moro et al 2012;Riahi et al 2011). According to Beckerman et al (2006) variation in incubation period could be attributed to characteristics of the mother affected by environmental conditions, such as mothers' age, rearing density and food quality and availability.…”

Life cycle of Raoiella indica (Acari: Tenuipalpidae) on ornamental plants, mostly Arecaceae

The red palm mite, Raoiella indica Hirst, has been primarily found associated with coconut and musaceous plants in the New World. However, it has also been recorded on several other palms, heliconiaceous and zingiberaceous species. This study was conducted to evaluate the suitability of different botanical families on which R. indica has been collected in the field and of arecaceous plants of the natural vegetation of the neotropics. In total, ten species of Arecaceae as well as Heliconia psittacorum [Heliconiaceae] and Alpinia purpurata [Zingiberacae] were evaluated, using coconut as a control. The study was carried out under controlled conditions (29 ± 0.5 °C, 60 ± 10% RH and photoperiod 12 h of light). Raoiella indica was able to complete immature development only on coconut, Adonidia merrillii, Ptychosperma macarthurii, H. psittacorum and A. purpurata. Duration of the immature phase (egg-adult) ranged between 21.5 days on coconut to 34.1 days on A. purpurata. Longevity was at least 50% greater and oviposition at least 38% higher on coconut than on other plants. Intrinsic rate of increase (rm) was higher on coconut (0.166) and A. merrillii (0.042), but negative on the other two plant species. Raoiella indica could not reach adulthood on any of the other ten arecaceous species considered in the study. The results suggested R. indica to be a threat to A. merrillii in addition to coconut, but not to other evaluated plants. However, complementary studies should be conducted to investigate whether the experimental procedures adopted in this study could not have prevented the mite from a better performance than it could have been under field conditions, especially in relation to Mauritia flexuosa, one of the dominant arecaceous plants in South America.

Neste estudo foi avaliada a abundância e a sazonalidade de Tetranychus urticae Koch, 1836 em três cultivares de Gerbera jamesonii Adlam., em cultivo comercial no sul do Brasil. Para avaliação destes parâmetros foram realizadas amostragens de abril de 2011 a fevereiro de 2012. Os ácaros foram obtidos a partir de flores e folhas retiradas de cada uma das cultivares. No total foram contabilizados 10.640 ácaros e de acordo com os testes, a cultivar "Pink Snow" apresentou maior abundância significativa. A análise estatística não evidenciou diferença entre o número de ácaros presentes nas folhas e flores. Em todas as variedades o maior número de T. urticae foi registrado na primavera
