A study was carried out in a fig orchard 'Roxo de Valinhos', located in Campinas County, State of São Paulo, Brazil, in order to evaluate different fig ostiolar protection systems against Zaprionus indianus (Diptera: Drosophilidae) oviposition. Adhesive tag, gel and Bordeaux mixture provided a significant reduction of fig fly infestation. The folia...

Brazil is the third-largest fruit producer in the world. One of Brazil’s biggest problems in producing and exporting fruits is the infestation of fruit flies. Species of Anastrepha, Bactrocera carambolae, and Ceratitis capitata constitute the economically important group. Anastrepha fraterculus, A. grandis, A. obliqua, A. pseudoparallela, A. zenild...

Because of fruit fly incidence, importing countries impose phytosanitary barriers to prevent the entry and spread of infested fruits. When fruits are not grown in fruit fly-free areas, some countries require quarantine treatments for fruit disinfestation before or during shipping. The objective of this study was to evaluate the use of a hydrotherma...

Fruit flies (Diptera: Tephritidae) cause significant losses during the production and marketing of horticultural products. Brazilian growers usually adopt full-coverage insecticide spraying to control fruit flies, but toxic bait is a more strategic technique, because reach efficacy and the target surface is the foliage and branches. We provide info...

There are risks involved in the production and exportation of fruit fly hosts due to the possible spread of tephritid pests during distribution. Anastrepha grandis attacks cucurbit fruits and is considered an A1 quarantine pest in many countries.
