This page represents the following TreeOfLife-200M taxonomic path.[1]
Based on museum specimen images from the TreeOfLife-200M dataset, Anastrepha pickeli exhibits the characteristic body form of a tephritid fruit fly.[1] The specimens display a distinct, patterned wing venation typical of the genus Anastrepha, with brownish markings on the wings. The thorax and abdomen show a yellowish-brown coloration, consistent with the general appearance of many species within this genus.[1]
Anastrepha pickeli is a tephritid fruit fly recognized as a significant pest of cassava (Manihot esculenta).[2] The species causes damage to both the fruits and stems of the host plant.[2]
Adult females oviposit in tender cassava stems. Upon hatching, the larvae bore through the stem, moving either upward or downward. When the larvae exit the stem to pupate, they create openings that allow latex to exude from the plant. This damage is frequently associated with the bacterium Erwinia carotovora var. carotovora, which can enter the plant during oviposition or larval exit, leading to rot. In young plants, this infection can be fatal or cause severe damage to the pith and cortex of vegetative propagation material.[2]
Research into the control of Anastrepha species on cassava has explored various methods, including attractants and insecticides. Laboratory studies have shown that a diet based on Brewers yeast significantly increases the fecundity of adult females. In field trials, a bait consisting of Brewers yeast combined with the insecticide EPN (ethil-O-nitrofenil) proved more effective at controlling adults than the insecticide alone.[2]
For monitoring, McPhail-type traps have been found to be twice as effective as sticky traps for capturing adults. Among natural attractants tested in these traps, hydrolyzed corn (at 2%) was the most effective. For larval control in the field, foliage application of fenthion (0.15%) has been identified as an effective and economical treatment, while soil application of carbofuran was found to be less effective.[2]
