Combinando estirpes virulentas de Beauveria bassiana e nematoides entomopatogênicos para o controle de pupas de Ceratitis capitata.

Neste trabalho, estirpes comerciais de Heterorhabitidis bacteriophora (Hb) e de Steinernema carpocapsae (Sc) foram avaliadas quanto a sua virulência à C. capitata, definindo-se doses efetivas, efeitos residuais e a combinação com LCB289

Optimum dose of ginger root oil to treat sterile Mediterranean fruit fly males (Diptera: Tephritidae)

The sterile insect technique (SIT) is widely used as part of an integrated approach to reduce field populations of the Mediterranean fruit fly (Ceratitis capitata, Diptera: Tephritidae). Aromatherapy based on exposure to ginger root oil (GRO) volatiles is known as a method to significantly improve the sexual performance of sterile medfly males, and is being used in many mass-rearing facilities around the world. However, the optimum dose of GRO is not well defined. This work evaluated in laboratory cages four different doses of GRO and a control (0, 0.1, 0.25, 0.5 and 0.75 ml/m3), and two different methods to hold flies prior to release (paper bags and plastic cages). The objective was to find the lowest dose that provides optimal improvement in mating performance of sterile males when competing with wild males for wild females and optimal reduction in fertility of wild females. Egg hatch, copula duration, the Relative Sterility Index (RSI), and a Competitiveness (C) value (based on RSI) were calculated for each treatment to assess male sexual performance and induction of sterility. The method used to hold flies did not influence the aromatherapy effect. The mean time spent by wild females in copula with wild males was significantly longer than with sterile males for all treatments, except when sterile males were treated with 0.1 ml of GRO/m3. Amongst all doses studied, it is recommended to apply the lowest dose, 0.1 ml of GRO/m3, since at this dose both the RSI and induced sterility reached the highest levels, and were not statistically different from the 0.25 and 0.5 GRO/m3 doses. Indeed, this dose showed a very significant improvement in the mating competitiveness of sterile males aromatically treated with GRO.Supplement 1

CeraTrap na coleta massal de Ceratitis capitata (Diptera: Tephritidae) em videiras no Vale do São Francisco.

A proteína hidrolisada CeraTrap é um atrativo alimentar recentemente introduzido no Brasil para ser usado na captura massal de moscas-das-frutas. O objetivo é empregar uma alta densidade de armadilhas no pomar no período em que os frutos estão suscetíveis ao ataque da praga. O CeraTrap foi avaliado em seis pomares de uvas finas de mesa localizadas no Vale do São Francisco, distribuindo-se 120 garrafas PET/ha

Manga: tratamento hidrotérrmico.

Técnica brasileira desenvolvida na década de 1990 e que consiste em mergulhar as frutas em água aquecida após a colheita tem sido fundamental para atender às exigências do mercado externo quanto ao controle de mosca-das-frutas, de modo a permitir o aumento das exportações de manga
