Megjegyzések:	Individuals of the same species often consistently differ in their behaviour across time and context. These stable differences are usually termed 'animal personality'. Parasitism is known to significantly influence the evolution of animal personality at least in part because more explorative individuals may meet parasites more frequently than less explorative ones. Previously, we have demonstrated that consistent individual differences (i.e. boldness, activity, exploration) can be measured in firebugs. As continuation, we examined here the relationship between firebug personality traits and their ectoparasitic mite loadsin a wild population. We showed that bugs that behaved in a more explorative way have more mites and we also found a marginally significant interaction between sex, boldness and activity: bolder and more active female firebugs were more infected. In addition, we experimentally tested whether an artificial infection causes any alteration in the bug's behaviour and whether there is any relationship between firebug personality and immune response. This treatment did not induce any alteration in bugs' personality. We found that bugs become more explorative but less active when repeating the experiment, but at the same time all personality traits (boldness, activity and exploration) were repeatable. Furthermore, firebugs with a stronger immune response behaved more boldly but also less actively.

Cím:	Personality traits across ontogeny in firebugs, Pyrrhocoris apterus / Gyuris Enikő, Feró Orsolya, Barta Zoltán
Dátum:	2012

Megjegyzések:	Consistent behavioural differences have long been recognized in animals but it still remains unclear how these traits change over ontogeny. As individuals can face different situations over their lives, and their life history expectation may not be the same in different life stages, one can expect that using different strategies in different life stages would be adventageous. Characteristics of animal personality across ontogeny could be measured at group and individual levels. Since personality alteration across time can be studied from various aspects one should use the following indexes: mean-level, differential, structural and individual consistency. We investigated whether common firebugs behave in the same way throug a major life stage transition, namely final ecdysis. We measured activity, boldness and exploration twice in the larval stage and also twice when bugs reached the adult stage. We found that the relative value of behavioural traits was stable across ontogeny and the correlation structure among behavioural traits remained constant over time. Nevertheless, larvae differed from adults in general in that they were bolder, explored their environment more thoroughly and seemed to be more active before final ecdysis. These results indicate that personality could change differently across major life stage transitions; therefore this importand factor needs to be considered in further research.

Cím:	Individual behaviour in firebugs (Pyrrhocoris apterus) / Enikő Gyuris, Orsolya Feró, András Tartally, Zoltán Barta
Dátum:	2010
Megjegyzések:	The concept of animal personalities has recently become of major interest as researchers began to wonder why animals within a given population show consistent behaviour across situations and contexts, what led to the evolution of such behavioural inflexibility and what mechanisms might underlie the phenomenon. A recent model explains individual differences in a population as the result of trade-off between present and future reproduction.We tested this model on the two wing morphs, i.e. short-winged (brachypterous) and long-winged (macropterous) specimens of the firebug (Pyrrhocoris apterus). Since it has been already demonstrated that the two wing morphs differ in their life-history strategies, this species is an ideal subject to test whether the specimens with different life-history strategies have different personalities as well. The results show that individuals behave consistently over time and across contexts, meaning observed bugs do have personalities. We also have found that in females, the two wing morphs have different personalities supporting the theoretical predictions, i.e. winged ones, which are supposed to have lower future reproductive value, are braver and more exploratory. We found no difference between the morphs in males. Differences in reproductive investment might explain this discrepancy between the sexes.
