“…A stone covered with honeydew was equally attractive for the A. aphidimyza larvae as a green peach aphid Myzus persicae . In an attempt to test the hypothesis of visual cues triggering the predator's response, higher predation was reported on the red over the green morph of same size pea aphids Acyrthosiphon pisum ; however, differences in olfactory cues or the nutritional value between the two morphs were not tested.…”

“…Although the species of aphid can have a direct influence on A. aphidimyza larval stages (e.g. through nutritional quality, prey quantity), larval prey preference has rarely been studied . This is also due to the fact that the adult females choose where their offspring will develop, by making decisions regarding egg‐laying location.…”

Aphidoletes aphidimyza is one of the most important predators used in the augmentative biological control of aphids, key pests of many crops worldwide. Adult females are very efficient in locating aphid infestations over a relatively long range, up to 45 m, and deposit eggs near or within aphid colonies. The predatory larvae are aphid generalists preying on several agriculturally important aphid species. The successful use of this biocontrol agent in agricultural systems depends on several biotic and abiotic factors. Among biotic factors, aphid species, plant structure, interspecific competition and intraguild predation may significantly impact the predator´s population dynamics. Key abiotic conditions include day lengths (above a critical threshold to prevent diapause), availability of mating sites in the crop, temperature (above 15 °C to enable egg laying), air relative humidity (above 70%) and availability of pupation sites. Although several successes have been reported in open field crops with naturally occurring or released populations, commercial releases are primarily used in protected crops. Optimized emergence boxes combining provisioning of food sources for the adults, integration with the technological advances that occurred in the greenhouse environment lately, insights into the nutritional ecology in open field crops and exploration of the genetic variability are proposed as future directions to improve adoption and efficacy of A. aphidimyza in crop protection. © 2018 Society of Chemical Industry

“…predation) for a longer time might lead to fitness losses of the animals. Smaller instars of M. persicae were shown to be preferably preyed upon by Macrolophus pygmaeus (Heteroptera: Miridae) as compared with larger aphid instars (Fantinou et al, 2009;Farhoudi et al, 2014). Thus, the fitness of Table 2. aphid nymphs can be improved when growing fast, particularly during early life stages.…”

“…2a,b). If younger nymphs are indeed exposed to higher rates of predation (Fantinou et al, 2009;Farhoudi et al, 2014), enhanced activity and exploration might increase the possibility to flee from a potential danger on the ground. Indeed, ontogeny-dependent differences in predator escape behaviour were likewise found in Nemobius sylvestris (Orthoptera: Gryllidae), in which predation pressure was highest in early-instar individuals (Dangles et al, 2006(Dangles et al, , 2007.…”

1. Life‐history traits of herbivores are shaped by the combination of various extrinsic and intrinsic variables. However, studies investigating the impact of both variables on insect behavioural phenotypes are rare, and research including the modulation of host plant quality by arbuscular mycorrhiza (AM) (extrinsic variable) and the herbivore developmental stage (intrinsic variable) on aphid behaviour is lacking. 2. To study the influences of extrinsic and intrinsic variables on aphid performance and behaviour, individuals of the generalist aphid pest Myzus persicae (Sulzer) were reared on Plantago lanceolata and Poa annua plants that were either non‐mycorrhized (NM) or mycorrhized (AM). Aphid performance was monitored over 2 weeks. Behavioural traits of nymphs were recorded twice during development after removing individuals from their feeding sites and placing them in an unknown environment (‘open field’), causing disturbance. Plant quality was determined by measuring the water content and leaf mass per area (LMA). 3. Differences in body mass of nymphs at day 6 dependent on plant species and treatment were compensated by the individuals within 4 days. Behavioural traits, considered as activity and exploration, were affected by the interaction between extrinsic and intrinsic variables (activity and exploration) and changed over ontogeny (activity). Independent of AM, a lower water content and LMA were recorded in P. annua leaves. 4. Overall, this study demonstrates that extrinsic and intrinsic variables need to be considered in combination and behavioural traits should be studied repeatedly during insect ontogeny to understand the complexity of microbe‐modulated plant–herbivore interactions.

“…The larvae exhibit a furtive hunting behavior and do not trigger the release of alarm pheromones by the aphids under attack (Lucas & Brodeur, 2001). The number of aphids consumed by A. aphidimyza larvae is highly variable and depends on aphid species and density (Harris, 1973), the temperature (Markulla et al, 1979), and also aphid color (Farhoudi et al, 2014).…”

Does insect mother know under what conditions it will make their offspring live?

According to the optimal oviposition theory, the larval success of insects depends on the oviposition site selection by females. Females are expected to choose a site with many resources and few competitors or predators to allow the best performance for their progeny, assuming that "mother knows best." However, this is not systematically observed. The Aphidoletes aphidimyza larvae are generalist aphid predators and females consequently lay their eggs near or inside aphid colonies. The goal of this study was to investigate the impact of intraspecific competition on oviposition behavior of A. aphidimyza females. First, we counted the number of eggs laid by a female on a leaf with 20 aphids, in the presence of 0, 2, 4, or 6 conspecific eggs or in the absence of eggs but in presence of 3 virgin females. The same experiment was also performed under choice condition with 2 oviposition sites. Our results show that the presence of low densities of conspecific eggs, or the presence of conspecific females, have no significant impact on the number of eggs laid by A. aphidimyza females. One of the hypotheses advanced to explain these results is the advantages of conspecifics presence. At low densities, the presence of eggs on an oviposition site can indicate the suitability of the site for the females. The conspecific presence can also insure a dilution effect against predator and increase the presence of potential mating partners for this monogenic species.
