“…Mantid emergence from individual oothecae exhibited a strong degree of synchronicity, with emergence typically concluding within 1 week. This observation was somewhat less synchronous than has been reported for other mantid species (Hurd 1988;Iwasaki 1996). On emergence, adult wasps were sexed and preserved, while mantids were reared individually on fruit flies in the context of other research projects.…”

“…Nymphal and adult mantids suffer from a variety of parasites (e.g., tachinid flies, Exorista bisetosa [Iwasaki 1993]), but by far the best known parasites of mantids are torymid wasps that attack mantid oothecae (egg cases) (Breland 1941;Grissell and Goodpasture 1981). Although the ecological relationships between these egg parasites and mantids have rarely been studied, other aspects of mantid life histories, population ecology, and community impacts have been well studied in a variety of habitats, including old fields and grasslands in the eastern United States (Hurd and Eisenberg 1984a, b;Snyder and Hurd 1995;Hurd 1994, 1998), Europe (Lawrence 1992), and Japan (Matsura et al 1975;Iwasaki 1996). Therefore, mantids and their associated parasites provide a system in which the effects of spatial aggregation on host susceptibility to parasitism can be studied within an established ecological context.…”

We report on spatial patterns of parasitism of oothecae (egg cases) of praying mantises (Stagmomantis limbata) by torymid wasps, Podagrion spp. Using collections of mapped mantid oothecae from Riparian sites in the Sonoran desert and Grassland sites in the Chiricahua Mountains (both in Arizona, USA), we characterized the spatial distributions of oothecae and parasitism. The likelihood of an egg case suffering some parasitism was higher at Grassland sites, which had high oothecal densities, than at low-density Riparian sites. However, experimental isolation of Grassland oothecae to densities comparable to Riparian sites reduced parasitism rates. At Riparian sites, parasitized oothecae exhibited on average the same extent of parasitism as parasitized oothecae at high densities but with much greater variation. Indeed, large fractions of Riparian oothecae suffered both severe (Ͼ50%) and light (Ͻ20%) parasitism, whereas most parasitized Grassland oothecae suffered intermediate levels of parasitism. Analysis of first nearest neighbor distances indicated that the parasite load of an ootheca did not depend on its immediate isolation. However, extending the analysis to include subsequent nearest neighbors (using a technique from spatial statistics called the R(K) function), we found that even though oothecae of S. limbata were spatially clustered, some oothecae in a (statistically defined) cluster escaped parasitism when overall oothecal densities were low. This pattern suggests that when oothecae are sparsely distributed, Podagrion wasps exploit only a fraction of the oothecae available locally, even though the oothecae are strongly aggregated relative to their overall density. We suggest this lack of congruency in the scales of oothecal deposition and parasitism at low densities (which is absent when oothecae are at high densities) may be explained in part by behavioral aspects of the parasite's reproduction, including increased host fidelity by relatively sedentary female parasites.

Galepsus Stäl is a genus within the Mantodea and has hardly been studied in Africa. The distribution of the Galepsus genus in Southern Africa was established, based on insect collection records, and the biology of Galepsus (Lygdamia) lenticularis Saussure, was studied. In Southern Africa, 11 species of Galepsus were recorded. The first record of Galepsus (Onychogalepsus) centralis Beier, in South Africa was recorded during this study. The mean number of eggs per ootheca was 49.8 (±21.1) and unfertilized oothecae were significantly shorter and contained fewer eggs than hatched and unhatched oothecae, suggesting that females might invest fewer resources into production of oothecae that will not produce prodigy. No parthenogenesis was observed during this study. Although the mean duration of the male and female nymphal stages were similar, longevity of adult females (91.2 ± 35.0 days) was three times longer than that of males (26.3 ± 15.4 days). This phenomenon as well as the long period (20 ± 14.1 days) between oviposition of different oothecae, and duration of the incubation period (20.25 ± 6.3 days) suggests a survival strategy to reduce competition between siblings. Total longevity of males (166.9 ± 38.8) and females (252.9 ± 54.2) differed significantly. This study provides information on the distribution of Galepsus spp. in Southern Africa and describes the biology of G. lenticularis under captive breeding conditions, and contributes to the understanding of various biological aspects of G. lenticularis which has never been studied before.

The giant African mantis, Sphodromantis viridis Forsskål, 1775 (Mantodea: Mantidae) was the most observed species of praying mantis in citrus orchards at Sohag Governorate, Egypt during 2017 and 2018 years. Besides, the Egyptian praying mantis, Miomantis paykulii (Stal, 1871) and the European mantis, Mantis religiosa, were observed in rare numbers. About 530 and 575 oothecae of mantis were collected in 2017 and 2018 respectively from about 46 hectares of citrus. The incubation of these oothecae resulted in complex fauna consisting of four hymenopteran parasitoids, Podagrion sp. (Torymidae: Hymenoptera), formicidae & Eupelmidae (Hymenoptera) and other hymenopteran specie, also four spider predators and Scolothrips sp. were found. Among the collected oothecae, totals of 28 and 25 oothecae hatched to mantis nymphs producing totals of 1536 and 1318 nymph/year for 2017 and 2018 years respectively. Podagrion sp. was the most common parasitic specie and the highest mean number of parasitoids/ootheca was in November with an average of 88 and 116 parasitoid/ootheca for 2107 and 2018 years respectively. Spiders were the most frequent among the oothecae fauna, as the spiders have emerged from the oothecae in the juvenile phase or adult. Incomplete parasitism was calculated after dissection of oothecae, the highest parasitism rate of oothecae was in May and March for 2017 and 2018 years, while the lowest rate was recorded in September for both years.
