Species diversity, novel interactions and absence of well‐supported host‐guided phylogenetic groupings of Neotropical Alternaria isolates causing foliar lesions in Solanaceae

Aim: To report the characterization of 120 Alternaria isolates inducing early blight-like foliar lesions in nine species of five Solanaceae genera collected across all macrogeographical Brazilian regions. Material and Results: Phylogenetic relationships were assessed via analyses of the Alternaria alternata allergenic protein-coding, glyceraldehyde-3-phosphate dehydrogenase and the calmodulin gene sequences. Most of the tomato isolates were placed into the Alternaria linariae cluster, whereas most of the potato isolates were grouped with Alternaria grandis. Novel host-pathogen interactions were also reported. Seventeen isolates were selected for morphometrical characterization, and a subsample of 13 isolates was employed in pathogenicity assays on tomato, potato, eggplant, scarlet eggplant, Capsicum annuum, Datura stramonium, Physalis angulata and Nicotiana tabacum. Eleven isolates were able to induce foliar lesions in tomatoes but none in C. annuum. Potato was susceptible to a subgroup of isolates but displayed a subset of isolate-specific interactions. Morphological traits were in overall agreement with molecular and host range data. Conclusion: Alternaria linariae and A. grandis were confirmed as the major causal agents of tomato and potato early blight, respectively. However other Alternaria species are also involved with early blight in solanaceous hosts in Brazil.Significance and Impact of the Study: The diversity and host-specific patterns of the Alternaria isolates from Solanaceae may have practical implications in establishing effective early blight genetic resistance and cultural management strategies especially for tomato and potato crops.

RESUMOA abobrinha italiana é cultivada em todo o território nacional e bastante consumida devido as suas características nutricionais e a sua praticidade e facilidade de preparo. Os insetos apresentam grande importância na cultura da abobrinha italiana, pois estas dependem de insetos para realizar a polinização, além disso, insetos podem causar danos às plantas e aos frutos. A s s i m , objetivou-se realizar uma avaliação da entomofauna presente na cultura da abobrinha durante seu ciclo. Foram implantados quatro canteiros de abobrinha italiana e durante seu ciclo, foram realizadas três capturas de artrópodes com armadilhas Pitfall e três coletas com armadilhas Moericke. As coletas foram realizadas quando as plantas estavam com 18, 46 e 65 dias de campo. Em cada coleta foram utilizadas duas armadilhas, de cada tipo totalizando seis armadilhas do tipo Pitfall e seis armadilhas do tipo Moericke. Após a coleta, os insetos foram classificados a nível de ordem. No estudo realizado, a ordem Hymenoptera apresentou a maior quantidade de insetos capturados, e totalizou 631 indivíduos. A armadilha do tipo Moericke capturou maior diversidade de insetos no início do desenvolvimento da cultura apresentando índice de Shannon de 1,61. A armadilha do tipo Pitfall apresentou maior diversidade de insetos quando a cultura estava em plena floração, e o índice de Shannon foi de 1,30. As armadilhas utilizadas no experimento foram eficientes na captura de artrópodes das ordens Coleoptera, Collembola, Diptera, Hemiptera e Hymenoptera A ordem que teve maior número de indivíduos capturados foi a ordem Hymenoptera, representando 48,91% dos artrópodes amostrados. PALAVRAS-CHAVE: Collembola, Cucurbitaceae, Hymenoptera.

Tomato golden mosaic disease, caused by the tomato severe rugose virus (ToSRV), is one of the most serious tomato diseases. ToSRV is transmitted by the whitefly Bemisia tabaci MEAM1, from a wide range of hosts. Introducing ToSRV in commercial fields probably can occur by transporting the virus from distant locations. However, our hypothesis is that the inoculum causing epidemic development might be related to nearby sources. This study evaluated the short‐range flight distance of B. tabaci MEAM1 (marked with detectable proteins and powder dye), through recaptures in yellow sticky traps, and the transmission of ToSRV by viruliferous B. tabaci MEAM1 to tomato plants placed at increasing distances from a release point. Evaluated whiteflies reached a maximum of 30 m from the release point, and no ToSRV‐infected tomato plants were detected at greater distances. These findings reinforce the suspicion that the epidemic‐supporting source of ToSRV inoculum must be close to commercial cultivation areas. About the efficacy of the type of markers used, of the two protein sources tested (pasteurized chicken egg‐white albumin and commercial soy‐based extracts as sources of albumin and lecithin, respectively), albumin was considered easier to detect. Marking with these proteins or with two dyes (blue or pink) did not affect B. tabaci MEAM1 mortality, although field tests showed that fewer marked than unmarked insects were recaptured. Dye marking was considered more practical because of the ease of detection. The study validates a new tool to understand the movement of B. tabaci MEAM1, based on different marking methods.
