“…Similarly, the largest male within a pair of males was more likely to mate. A positive correlation between male size and mating success has been reported for a range of insect species (Gage & Barnard, ; Horton et al ., , ; Ryder & Siva‐Jothy, ; Honěk, ; Gao & Kang, ) and has been previously observed in other beetles (Harari et al ., ; Kotiaho, ; Wang, ; O'Luanaigh et al ., ). Large male size may confer a mating advantage through intra‐ or intersexual competition in C. tenebrionis .…”

An understanding of the relative importance of extrinsic and intrinsic factors in determining the potential distribution and mating success of individuals is critical for the successful monitoring and management of pest species. Using a combination of field observations and a caged field experiment, we explored the roles of environmental and individual variation on the formation of mating aggregations and mating success in the buprestid beetle Capnodis tenebrionis (Linnaeus, 1767), a pest species of stone fruit trees. Our field observations revealed that the formation of aggregations is influenced by a range of environmental factors including temperature, photoperiod, and population density. However, aggregations were not at random and were more likely to occur on the section of the plant with highest incidence of solar radiation and thus higher temperatures. Data from our experiment with caged beetles in the field further indicate that the reproductive behavior of this species varies with temperature. The probability of a successful mating occurring was also positively related to both male and female size. Females of C. tenebrionis mate several times over a 4-h period, but generally not with the same male. Information obtained from these studies is useful to define the most appropriate time for pest control, especially adopting strategies that interfere with reproduction.

“…cicla . Larger individuals could have higher fecundity (reviewed by Honek, 1993), chances of mating (Rhainds et al., 1999; Honek, 2003; Sisodia & Singh, 2004), egg fertility (Yenisetti & Hegde, 2003; Jiménez‐Pérez & Wang, 2004), dispersion capacity, and longevity (Nylin & Gotthard, 1998; Colinet et al., 2007). Altogether, our results suggest that previous experience could not overcome oviposition preferences that appear driven by fitness benefits for offspring.…”

Host preferences of phytophagous insects, although generally showing a strong hereditary component, can be modified by experience. Here we aim to elucidate the relative roles of larval and adult experience on host plant selection by Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), a widely distributed pest on ornamentals and vegetables. Laboratory and field experiments evaluating feeding and oviposition preferences of L. huidobrensis females with larval, adult, or larva plus adult experience on either Vicia faba L. (Fabaceae) or Beta vulgaris var. cicla L. (Chenopodiaceae) were performed. Also, we measured offspring performance of L. huidobrensis on both host plant species. Our results show that L. huidobrensis females strongly preferred V. faba over B. vulgaris var. cicla for feeding and egg laying. Only larval and adult experience acting in concert modified feeding behaviour, whereas oviposition preferences remained unaltered regardless of female previous experience. Offspring performance was higher on the preferred host (V. faba), indicating a preference–performance linkage for this leafminer. Experience on B. vulgaris var. cicla could not overcome oviposition preferences, which appear driven by fitness benefits for offspring.

“…To assess the study results, considering first the specific conditions of courtship and mating in natural populations of P. apterus is useful. The copulation behaviour of this species has often been studied experimentally in the laboratory [ 44 ]. When two males of contrast size were offered to a female, the larger of two males was more likely to mate in cases when the experimental female was large, but not when the experimental female was small.…”

“…Body size may play a role in the mutual selection of mating partners. In laboratory experiments, females were observed to prefer larger offered males [ 44 ], but the benefit they derive from copulation with a large male has not been investigated. The size of accessory glands in males of P. apterus is large, with a length of approximately 2 mm [ 45 ], which is more than one-fifth of the average length of the male’s body.…”

Effect of Male Body Size on Female Reproduction in Pyrrhocoris apterus (L.) (Heteroptera, Pyrrhocoridae)

Females and males of the abundant heteropteran species Pyrrhocoris apterus (L.) mate with the larger of the available partners. The male benefits from copulation with a large female, which is more productive than a small female. However, the benefit to females from copulation with a large male has not yet been investigated. Overwintered sexually immature adults were transferred from the field to indoors for a long day at 25 °C and subsequently kept as female-male pairs with different partner size ratios. The female lays eggs in several successive clutches. We investigated the influence of male size on the number and weight of eggs in individual clutches and the time elapsed from the transfer to their deposition. These characteristics of reproduction were first regressed on female size, and residuals of this regression were then regressed on male size. The positive effect of increasing male size on the characteristics of female reproduction manifested as a significant value of the latter regressions. The expected positive effect of increasing male body size on female reproductive characteristics was not detected. Several reasons for this deficiency are discussed.
