“…Foraging and reproductive behaviors may also be modulated in subtle ways by responses to daylength. For example, photoperiod interacts with temperature and host plant to influence the predation rate of Macrolophus pygmaeus Rambur (Hemiptera: Miridae) (Perdikis et al, 2004). Rasekh et al (2010) demonstrated that adult females of the parasitoid Lysiphlebus fabarum (Marshall) foraging for aphids increase their patch residence time when they develop under short days within their host.…”

“…The experiments were initiated between 14:00-16:00 h since the closely associated predator M. pygmaeus was found more active during the afternoon (Perdikis et al 2004). The position of the predator was recorded on each of the two plants but also elsewhere in the cage.…”

The host plant selection of the predator Macrolophus melanotoma (Costa) (=M. caliginosus Wagner) (Hemiptera: Miridae) was studied between: i) its major non-crop host plant, Dittrichia viscosa L. (W. Greuter) (Asteraceae) and the solanaceous plants eggplant, pepper and tomato, and ii) between eggplant, pepper and tomato, in choice experiments. The experiments were performed in cages where two potted plants without prey were placed. In each replicate, an adult predator was released in the centre of the cage or on the solanaceous plant. The position of the released predator in each cage was recorded at intervals of 20min, 1, 2, and 24h after its introduction. The results showed that M. melanotoma had a high selection preference rate for its origin host plant (D. viscosa) irrespectively of the solanaceous plant that was present in the cage. The experiments investigating the relative preference of M. melanotoma when given access only to solanaceous plants revealed that it preferred eggplant at higher rates than pepper and tomato. These data indicate that M. melanotoma originating from D. viscosa patches might have a very low potential to colonize pepper or tomato crops in the open field. However, its potential to colonize eggplant crops should be further evaluated.

“…Previous studies have manipulated the external environment (e.g. temperature or light) to increase development rates (Yampolsky and Scheiner 1996, Gillooly et al 2002, Perdikis et al 2004, Nabeta et al 2005, but this is not independent of the other impacts that an increase in temperature will have on organisms within a population, including increasing physiological rates across all ages and stages of organisms. Mathematical models have shown that maturation rate plays a large role in the stability and cycling of population dynamics, with faster maturation rates leading to increased reproduction and population instability (Caswell 2001, Murdoch et al 2003.…”

Population fluctuations can be affected by both extrinsic (e.g. weather patterns, food availability) and intrinsic (e.g. life‐history) factors. A key life‐history tradeoff is the production of offspring size versus number, ranging from many small offspring to few large offspring. Models show that this life‐history tradeoff in offspring size and number, through maturation time, can have significant impacts on population dynamics. However, few manipulative experiments have been conducted that can isolate life‐history effects from impacts of extrinsic factors in consumer–resource systems. We experimentally tested the effect of an offspring size–number tradeoff on population stability and food availability in a consumer–resource system. Using Daphnia pulex, we created a shift from many, small offspring being produced to fewer, larger offspring. Two sets of experiments were performed to examine the interaction of an extrinsic factor (light levels) and intrinsic population structure on dynamics, and we controlled for the ingestion pressure on algal prey at the time of the manipulation. We predicted that the tradeoff would impact internal consumer population characteristics, including biasing the stage structure towards adults, increasing adult size, and increasing average population‐level reproduction. This adult‐dominated stage structure was predicted to then lead to instability and a low quantity–high quality food state. Under all light levels, the manipulated populations became dominated by large adults. Contrary to predictions, the amplitudes of fluctuations in Daphnia biomass were lower in populations shifted to few–large offspring, representing higher stability in these populations. Furthermore, in high light conditions, a stable low Daphnia – high algae biomass (low food quality) state was observed in few–large offspring treatments but not in control (many–small offspring) treatments. Our results show a strong link between light levels as an extrinsic factor and the life‐history tradeoff of consumer offspring size versus number that impacts consumer–resource population dynamics through feedbacks with resource quality.
