Fruit Flies (Diptera: Tephritoidea) and Parasitoids (Hymenoptera) Associated with Native Fruit Trees in the Chaco Biome.

Fruit flies (Diptera: Tephritoidea) are the main pests over important fruits and vegetables. In this research was evaluated the tritrophic interactions of fruit flies and their parasitoids occurring in native fruits in the Chaco Biome. Fruit sampling was carried out monthly in three areas of vegetation communities in Chaco Biome: Forested Steppic Savanna, Wooded Steppic Savanna, Park Steppic Savanna, Porto Murtinho-MS, Brazil, from April 3, 2017, to November 16, 2018 (totaling 20 samples).

Spatial distribution and control levels of Anastrepha spp. (Diptera: Tephritidae) in guava orchards.

This study aimed to know the patterns of spatial distribution of Anastrepha spp. and establish a criterion for determining the appropriate time for pest control. For this, 90 McPhail traps were used as Sampling Units (SU) divided into three commercial orchards of Novo Milênio guava with a total area of 14 ha.

Sequential sampling plan for fruit fly species of the Genus Anastrepha (Diptera: Tephritidae) in guava orchards.

This study aimed to elaborate a sequential sampling plan for Anastrepha species in commercial orchards of guava Psidium guajava Novo Milênio cultivar. Samplings were carried out in three orchards in the State of Mato Grosso do Sul. Fruit flies were sampled for 23 weeks.
