Age estimation of Mexican fruit fly (Diptera: Tephritidae) based on accumulation of pterins.
A common method of aging adult flies, fluorescence spectrometry, was used to monitor the increase of overall pterine titer in head extracts of Anastrepha ludens (Loew). Accumulation of fluorescent compounds was measured as a function of chronological age of flies maintained at 17 and 27 degrees C. Although relative fluorescence increased with age, field studies revealed that this phenomenon cou...
متن کاملBehavioral and Electrophysiological Responses of the Mexican Fruit Fly (diptera: Tephritidae) to Guava Volatiles
The behavioral and electrophysiological responses of males and females of the Mexican fruit fly Anastrepha ludens (Loew) to guava ( Psidium guajava L.) volatiles were investigated in laboratory tests. Males and females were significantly more attracted and landed more often on guava fruits than yellow spheres used as control in the wind tunnel. Also, both sexes were more attracted to Porapak Q ...
متن کاملPhotoactive dye insecticide formulations: adjuvants increase toxicity to Mexican fruit fly (Diptera: Tephritidae).
The efficacy of photo active dyes as insecticides depends on the ingestion of the dye by the target insect and the activity of the dye at sensitive sites or on essential chemical functions. The site of this activity in insects is not understood, but we have found that certain chemical additives enhance the toxicity of phloxine B in the Mexican fruit fly. A series oftests with commercial adjuvan...
متن کاملNontarget insects captured in fruit fly (Diptera: Tephritidae) surveillance traps.
Traps baited with synthetic lures (ammonium acetate and putrescine) captured as many Mexican fruit flies as the traditional torula yeast/borax slurry, but with far fewer (ratio 5:1) nontarget insects. Ninety percent of the nontarget insects were dipterans. Consequently, neither trap is efficacious against other citrus pests, which are mainly Hemiptera or Lepidoptera. Although the nontarget catc...
متن کاملEvaluation of the efficacy of the methyl bromide fumigation schedule against Mexican fruit fly (Diptera: Tephritidae) in citrus fruit.
Methyl bromide fumigation is widely used as a phytosanitary treatment. Mexican fruit fly, Anastrepha ludens (Loew) (Diptera: Tephritidae), is a quarantine pest of several fruit, including citrus (Citrus spp.), exported from Texas, Mexico, and Central America. Recently, live larvae have been found with supposedly correctly fumigated citrus fruit. This research investigates the efficacy of the pr...
