Research paper thumbnail of Transgenerational effects of pest management strategy on fluctuating asymmetry in the European earwig Forficula auricularia: Being the progeny of a mother who lived in conventional orchards makes you more asymmetric than having a mother who lived in insecticide free orchards

Fluctuating asymmetry (FA), defined as the random non-directional deviation from perfect bilatera... more Fluctuating asymmetry (FA), defined as the random non-directional deviation from perfect bilateral symmetry, is considered to reflect developmental instability in bilaterally symmetrical organisms. It has been commonly used as a reliable biomarker of environmental stresses in natural populations. In agroecosystems, FA may arise through transgenerational influence of insecticides. We measured fluctuating asymmetry on unexposed progeny of Forficula auricularia mothers sampled in orchards that used no to frequent insecticides’ applications. Seven morphometric traits were measured on both right and left side and fluctuating asymmetry was calculated. Among these seven traits, four were more asymmetric when the progeny was born from a mother who lived in conventional orchards that used insecticides frequently compared to a mother who lived in insecticide free orchards. Males were more asymmetric than females for all traits but pest management strategy influenced FA in a similar way for bo...

Research paper thumbnail of How lasting are the effects of pesticides on earwigs? A study based on energy metabolism, body weight and morphometry in two generations of Forficula auricularia from apple orchards

To avoid adverse side effects, there is a growing interest in promoting alternative methods including biological control based on the use of natural enemies. The European earwig Forficula auricularia L. (Dermaptera: Forficuidae) is an effective predator in apple orchards. Pesticide pressure has been shown to divert energy resources which could have a negative impact on life history traits. In this study we assessed (i) whether variations in pesticide exposure could differentially impact energy reserves, body weight and morphometric parameters of F. auricularia, and (ii) whether these effects persist into the next generation reared under optimal conditions. Individuals from the first generation were collected in late October from organic, IPM and conventional orchards. The next generation was obtained under a rearing program, in the absence of pesticide exposure. Earwigs collected from conventional orchards exhibited lower values for all morphometric parameters compared to those collected in organic orchards. However, a relaxed period without pesticide exposure (in autumn) appears to have allowed the females to recover their energy reserves to ensure reproduction and maternal care. Glycogen contents were the reserves that were more easily restored. However, probably due to the rearing conditions (food ad libitum), all the earwigs from the second generation exhibited higher body weights and energy reserves than their parents.
