AbstractThe high density of the field crickets Gryllus pennsylvanicus (Burmeister) and Nemobius fasciatus (DeGeer) under test trees in an unsprayed orchard, and the high mortality of apple-maggot pupae, Rhagoletis pomonella (Walsh), in test lots at the same time of year, suggested that crickets may have preyed heavily on the pupae and thus have constituted important mortality factors. Laboratory observations showed that crickets can detect, disinter, and consume apple-maggot pupae in simulated natural surroundings.

Details of a method originated by A.C. Neville for aging adult insects by counting daily growth rings in tibial or other body sections are given. A test of the method's accuracy using laboratory-reared field crickets (Gryllus pennsylvanicus and Gryllus veletis) showed that the number of growth rings counted is equivalent to the number of days past adult molt until the insect is approximately 25–30 days old, when cuticle growth is completed and rings are no longer added. Field populations of the two cricket species sampled in 2 years seldom contained individuals with more than 18 rings. Several applications for the technique to ecological and behavioral studies are given, using examples from data on G. veletis and G. pennsylvanicus.

Female Choosiness

Intrinsic factors such as female age and mating status have been found to affect female choosiness. However, as these factors are often confounded in the wild because mated females are usually older individuals, the relative influence of these two factors on female behaviour is unclear. Using a fully factorial design, we tested the relative effects of age and mating status of female field crickets ( Gryllus pennsylvanicus Burmeister, 1838) on both (i) the probability that she would mate and (ii) her latency to mate. We found that virgin females were both more likely to mate and copulated more quickly than mated females, but female age had no significant effect on either the probability of mating or the latency to copulate. These results clearly show that mating status is more important in determining female mating behaviour than age. We suggest that previous work which showed an age effect on female choosiness in virgins alone might be of reduced relevance if most females do not remain unmated for long.

Few studies have addressed whether terrestrial insects assess predation risk via chemical cues. We exposed predator-naïve fall field crickets ( Gryllus pennsylvanicus Burmeister, 1838) to filter paper containing the chemical cues of three wolf spiders ( Hogna helluo (Walckenaer, 1837), Rabidosa rabida (Walckenaer, 1837), Rabidosa punctulata (Hentz, 1844)), the house cricket ( Acheta domesticus L., 1758,) and blank filter paper. Crickets exhibited greater immobility and reduced speed of movement when exposed to chemical cues of all three spider species. Crickets exhibited reduced speed with increasing mass of R. punctulata, suggesting that larger spiders may pose a greater risk. Cricket response did not differ between cues of H. helluo fed conspecific crickets versus H. helluo fed house crickets, suggesting that crickets cannot distinguish between cues from H. helluo fed phylogenetically similar crickets. Our work nevertheless demonstrates that naïve field crickets respond to chemical cues of several species of wolf spiders.

The evolutionary theory of aging proposes that senescence is related to decreased selection against deleterious mutations acting late in life. Senescence, i.e., an increase in intrinsic mortality with age, should reflect levels of extrinsic mortality early in life. We tested these predictions using two species of field cricket, Gryllus integer and Gryllus pennsylvanicus. Gryllus integer males are host to a sex-biased parasitoid fly, which orients to the male calling song. As a result, males have reduced life expectancy compared with females in the field. In contrast, G. pennsylvanicus males and females appear to have similar life expectancies in the wild. Thus, we predicted that there would be a significant species × sex interaction, with G. integer males having the shortest life-span. In two replicates, we found that males of both species died at a significantly younger age than females. However, no evidence of a species × sex interaction was found: in the first replicate, G. integer males died earliest, in the second replicate, G. pennsylvanicus males died earliest.

Male Courtship Behavior

Abstract Background The hybridizing field crickets, Gryllus firmus and Gryllus pennsylvanicus have several barriers that prevent gene flow between species. The behavioral pre-zygotic mating barrier, where males court conspecifics more intensely than heterospecifics, is important because by acting earlier in the life cycle it has the potential to prevent a larger fraction of hybridization. The mechanism behind such male mate preference is unknown. Here we investigate if the female cuticular hydrocarbon (CHC) profile could be the signal behind male courtship. Results While males of the two species display nearly identical CHC profiles, females have different, albeit overlapping profiles and some females (between 15 and 45%) of both species display a male-like profile distinct from profiles of typical females. We classified CHC females profile into three categories: G. firmus-like (F; including mainly G. firmus females), G. pennsylvanicus-like (P; including mainly G. pennsylvanicus females), and male-like (ML; including females of both species). Gryllus firmus males courted ML and F females more often and faster than they courted P females (p < 0.05). Gryllus pennsylvanicus males were slower to court than G. firmus males, but courted ML females more often (p < 0.05) than their own conspecific P females (no difference between P and F). Both males courted heterospecific ML females more often than other heterospecific females (p < 0.05, significant only for G. firmus males). Conclusions Our results suggest that male mate preference is at least partially informed by female CHC profile and that ML females elicit high courtship behavior in both species. Since ML females exist in both species and are preferred over other heterospecific females, it is likely that this female type is responsible for most hybrid offspring production.

Cellular Destruction

Cellular reactions to infections of Turgida turgida (Rudolphi, 1819) in field crickets (Gryllus pennsylvanicus (Burmeister) (=Acheta pennsylvanicus Burmeister)) were studied. Most larvae reached the epithelial cells of the ileum. These larvae caused little cellular destruction or haemocytic response until 18 h after infection. Syncytia of epithelial cell origin had formed around larvae by 28 h after infection. Initially, each syncytium was surrounded by haemocytes and later, by a wall with two well-defined layers. The epithelial layer of the alimentary tract had regenerated beneath the capsule by 48 days. Occasionally larvae penetrated directly into the haemocoel and were surrounded by haemocytes and(or) became melanized.
