II Caracterização das injúrias causadas por Frankliniella occidentalis no morangueiro

Predatory mites double the economic injury level of Frankliniella occidentalis in strawberry

“…This is consistent with other recent studies (Easterbrook 2000; Nondillo et al 2010). Earlier reports of fruit malformation by thrips may have been reporting capsid damage (Buxton and Easterbrook 1988).…”

“…The limited data on the susceptibility of different strawberry fruit stages to bronzing appear contradictory. Steiner and Goodwin (2005a) found bronzing occurred at the young green fruit stage, Coll et al (2007) found bronzing occurred on mature fruit and Nondillo et al (2010) found young and mature fruit stages equally susceptible to bronzing. Further data are needed to identify the timing of damage and the thrips stage(s) causing that damage so that growers can take appropriate action.…”

First record of thrips species and their damage to carrot in Alto Paranaíba

“…Among the observed symptoms caused by the thrips complex in the leaflets and the rachis of D. carota leaves, where they caused necrotic patches throughout the upper third of the leaf rachis (Figure 1a), as observed in watermelon crops when the attacked parts present a burnt or silvery appearance and dark spots (Michereff Filho et al, 2010), during the suction of the intracellular content by the thrips, the cells, while extracted, give to the plant tissue silver spots and later brownish spots due to the extravasated cells and accompanied by black spots that are the faeces deposited by thrips (Nondillo et al, 2010) (Figure 1b), and foliar shrivelling (Figure 1c) similar to the most characteristic symptoms of tomato "vira-cabeça" disease, transmitted by viruses of the Tospovirus genus disseminated by thrips that cause foliar distortion necrosis in young leaves and death of the stems (Albuquerque et al, 2012).…”

First Record of Heliothrips haemorrhoidalis (Thysanoptera: Thripidae) Causing Damage on Greenhouse Strawberries

“…A greenhouse bioassay was conducted to confirm the damage caused by H. haemorrhoidalis in strawberries. Damage characterization was performed with cageconfined individuals following the methodology described by Nondillo et al (2010). Each cage was set up with 1 leaf or 1 semi-ripe strawberry fruit, free from arthropod-induced damage, resulting in a total of 20 replicates for each plant part.…”
