Relative Attractiveness

Grapefruits and sweet oranges were equally attractive to, and elicited comparable oviposition behavior from, naïve laboratory-strain female Mexican fruit flies, Anastrepha ludens (Loew), in wind-tunnel experiments. Neither fruit attracted nor elicited oviposition behavior from naïve wild females. For laboratory females, experience with either grapefruits or oranges enhanced attraction to both fruits and enhanced attraction to the experienced fruit more so than to the other, but did not affect oviposition propensity. For wild females, experience with either fruit enhanced attraction to both fruits, enhanced attraction to the experienced fruit more so than to the other, and increased oviposition propensity on both fruits. Also, wild females experienced with grapefruits oviposited more readily in grapefruits than did those experienced with oranges. Both laboratory and wild females experienced with either fruit directed less oviposition behavior toward wind-tunnel walls than did naïve females. Laboratory males were attracted to both fruits, but wild males were attracted to neither. Overall, experience with fruit had smaller effects on responses of males compared with effects on females.

Temperature Extremes

Persistence of mass-reared, radiosterilized Mexican fruit flies, Anastrepha ludens (Loew), released at a target site was measured by trap-back. Released flies persisted in greater numbers during the winter months, with lowest numbers recovered in the summertime. Nocturnal releases were equally effective as morning releases in terms of persistence. Afternoon releases yielded better results in the winter but should be avoided in summer. Lowest persistence occurred in months with temperature extremes.

Biological Attributes

Doryctobracon areolatus (Szépligeti), a solitary endoparasitoid native to the Neotropics, attacks eggs and early instar larvae of Anastrepha fruit flies, and can enter diapause under tropical and subtropical conditions. We aimed to test if biological attributes, such as size, flight ability, starvation resistance, longevity and fecundity of diapausing individuals differ from those of non-diapausing ones. Parasitoids were obtained from a laboratory colony reared on Anastrepha ludens (Loew) larvae. Parasitized host puparia were sorted in two cohorts according to their diapause condition. Developmental time from egg to adult ranged from 18 to 31 days in non-diapausing parasitoids, and 70 to 278 days for diapausing individuals. Pupal weight and adult measurements were higher in non-diapausing than in diapausing parasitoids. There were no differences in adult longevity, starvation resistance, and emergence between diapausing and non-diapausing wasps. Flight ability and fecundity rates were greater in the non-diapausing than in the diapause cohort. The proportion of female offspring was greater in the non-diapausing cohort (42.5%), whereas in the diapausing cohort the male offspring proportion was greater (62.4%). Both cohorts produced diapause offspring, but the non-diapausing cohort produced more (26.6%) than the diapausing one (9.1%). Maternal age had a significant effect on the proportion of diapause offspring: in 26 to 34 days old non-diapausing females, 78.9% of their offspring entered into diapause. These results confirmed that diapause affects the biological attributes of D. areolatus. The observed differences contribute to better understand the diapause influence on the colonization and rearing process of this species and its use as biocontrol agent.
