Influence of handling and conditioning protocol on learning and memory of Microplitis croceipes

“…Female M. croceipes were conditioned with 3‐octanone at a release rate of 2 µg h −1 using a membrane loaded with pure chemical as described in Heath et al. (1996).…”

Two Low-Cost Food Attractants for Capturing <I>Toxotrypana curvicauda</I> (Diptera: Tephritidae) in the Field

“…However, with the exception of the sex pheromone identiÞed by Chuman et al (1987) and evaluated by Landolt et al (1988), Heath (1990), andHeath et al (1996), as well as the potential papaya fruit volatiles tested in the laboratory by Landolt et al (1992), no other attractants had been so far identiÞed for the papaya fruit ßy. The latter renders our Þndings here of practical signiÞcance, given that brown sugar and pineapple juice not only proved to be attractive to T. curvicauda under Þeld conditions but also both substances are cheap and readily available.…”

“…Different types of traps have been used for capturing T. curvicauda, including sticky green spheres resembling a papaya fruit, cylindrical green opaque plastic traps with a toxic or sticky material and cylindrical sticky green paper traps (Landolt et al 1988(Landolt et al , 1991Heath et al 1996). However, with the exception of the sex pheromone identiÞed by Chuman et al (1987) and evaluated by Landolt et al (1988), Heath (1990), andHeath et al (1996), as well as the potential papaya fruit volatiles tested in the laboratory by Landolt et al (1992), no other attractants had been so far identiÞed for the papaya fruit ßy.…”

“…In Þeld studies, Landolt et al (1992) developed a Þeld trap system based on the sex pheromone 2,6-methylvinyl pyrazine produced by the male, using traps resembling papaya fruits. Later, Heath et al (1996) improved the pheromone-based trapping system and developed a series of new trap models. Unlike other tephritid ßies, T. curvicauda is not attracted to hydrolyzed protein or the types of odors identiÞed as attractants for other fruit ßies (Sharp and Landolt 1984).…”

Padrões de emissão acústica em moscas-das-frutas do gênero Anastrepha (Diptera: Tephritidae) e suas implicações no isolamento reprodutivo pré-copulatório

“…Pode haver diferenças no horário de atividade de cortejo (Figura 1) de acordo com a espécie e das condições locais, como luminosidade, temperatura e umidade . Acredita-se que mudanças nos horários de cortejo e cópula estejam envolvidos no processo de especiação em simpatria por alocronia , Miyatake et al 2002 A liberação de feromônio masculino ocorre normalmente com a eversão das pleuras abdominais e da bolsa anal (podendo haver também participação das glândulas salivares - Lima et al 2001), sendo registrada em Anastrepha (Nation 1981, Lima et al 2001, Robacker et al 2009), Toxotrypana (Chuman et al 1987, Heath et al 1996, Ceratitis (Nation 1981, Gonçalves et al 2006, Bactrocera (Perkins et al 1990, Krohn et al 1992, Khoo & Tan 2005, Rhagoletis (Prokopy 1975, Raptopoulos et al 1995, Platyparea (Thibout & Auger 1999, Casaña-Giner et al 2001, Rioxa (Pritchard 1967). Feromônios sexuais femininos também foram registrados em Bactrocera (Mazomenos & Habiotaks 1981, Mazomenos 1984.…”
