“…Malo et al (2005) exposed A. ludens fruit flies to fruit volatiles and yellow spheres in a wind tunnel, to compare the behavioural responses of those insects, observing that both males and females were significantly more attracted to fruit volatiles than to unscented spheres. Gregorio et al (2012) reported finding more A. fraterculus eggs in substrates containing guabiroba ( Campomanesia xanthocarpa ) and peach pulp than in control substrates. Those authors attributed that preference to greater chemical compatibility between those substrates and the insects, with the larger numbers of eggs presumably reflecting the more adequate nutritional quality of the substrates for immature development.…”

Interspecific competition between individuals of different species can result in reductions in their fecundity, growth or survival, reflecting differential exploitation of resources that become intensified due to spatial co‐occurrence, ecological similarity and increased population densities. As two species cannot occupy the same niche, coexistence is only possible if the available resources are used in non‐overlapping manners such as niche partitioning or the use of refuges. Among agricultural insect pests, such as fruit flies of the family Tephritidae, competitive interactions can result in competitive displacement, host changes, or the expansion or restriction of the numbers of hosts utilized that can have negative consequences for human agricultural activities. We evaluated the competitive interactions between two fruit fly species of the genus Anastrepha, Anastrepha obliqua (Macquart, 1835) and Anastrepha fraterculus (Wiedmann, 1830), on their respective preferred hosts (mangoes and guava). Experiments of larval competition and competition for ovipositioning sites by adult females were performed to compare the parameters of larval development time, numbers of pupae and emerged adults and numbers of ovipositions in the presence or absence of interspecific competition. We observed that the interactions between those species were asymmetrical and hierarchical, and our results suggest a competitive displacement of A. fraterculus by A. obliqua when those two species are present on the same fruit, whether mangoes or guavas.

“…Several factors drive oviposition in insects: availability of food ( Stahlschmidt et al, 2014 ), assessment of threat from conspecifics ( Shelly, 1999 ; Ekesi et al, 2009 ), natural predators ( Van Mele et al, 2009 ), and most importantly, ovipositional stimulation and cues from the host ( Freeman and Carey, 1990 ; Kamala Jayanthi et al, 2012 , 2014a , b ). Insects carry the memory of ovipositional stimulant cues that are a part of the host volatiles which support their progeny survival ( Gregório et al, 2012 ; Kamala Jayanthi et al, 2014a ). A gravid female insect chooses the best possible oviposition sites to provide an environment suitable for the proper development of its progeny ( Fontellas-Brandalha and Zucoloto, 2004 ; Rattanapun et al, 2009 ).…”

Is the Natural Instinct to Oviposit in Mated Female Oriental Fruit Fly, Bactrocera dorsalis More of a Brain-Independent Act?

What physiological and neuro-molecular changes control the female oviposition behavior post-mating in insects? The molecular changes that occur in a gravid female insect are difficult to dissect out considering the distinct behavioral patterns displayed by different insect groups. To understand the role of the brain center in Oriental fruit fly, Bactrocera dorsalis oviposition, egg-laying behavior was analyzed in γ-octalactone exposed, decapitated mated B. dorsalis females. Interestingly, the females displayed a possible urge to oviposit, which suggests a natural instinct to pass on the gene pool. Expression analysis of certain genes involved in oviposition behavior was also carried out in these insects to explore the molecular aspects of such behavior. This study tries to assess the involvement of brain center in egg-laying and also explore the role of certain neurotransmitter-related receptors in decapitated B. dorsalis oviposition behavior. Our results indicate that B. dorsalis oviposition behavior could potentially have a bypass route of neuronal control devoid of the brain. The study reported here establishes that decapitation in gravid females fails to abolish their ability to sense ovipositional cues and also to oviposit.

“…Similar results were obtained with A. fraterculus, in which exposure to guabiroba-based [Campomanesia xanthocarpa O. Berg. (Myrtaceae)] or peach-based [Prunus persica (L.) Batsch (Rosaceae)] artificial fruits influenced female selection (Greg orio et al, 2012).…”

We evaluate the influence of prior exposure to artificial substrate for oviposition on learning and memory in the fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae). Some females were previously exposed to artificial fruits made of water, agar, and blackberry [Rubus spec. (Rosaceae)] or guava [Psidium guajava L. (Myrtaceae)] pulp for 48 and 72 h. We also studied adult flies exposed for 72 h to essential oil of lemongrass [Cymbopogon citratus (DC) Stapf, Poaceae] and adult flies from larvae exposed to the oil. Control females were naive with respect to these experimental substrates. Prior experience with blackberry‐based artificial fruits resulted in an increase in the number of punctures and deposited eggs by A. fraterculus, and memory lasted for up to 72 h. On the other hand, fly behavior was independent of exposure to guava‐based substrate. Prior exposure of 1‐ or 15‐day‐old females to artificial substrate with lemongrass oil modified innate substrate selection behavior. The scent of lemongrass oil during the larval stage modified innate oviposition responses of adult A. fraterculus. The study shows that A. fraterculus females are able to learn and retain information through chemical stimuli released by both host (blackberry and guava) and non‐host (lemongrass) species, and they can use olfactory memory obtained during the larval stage to select oviposition sites.
