“…During egg guarding, mothers continuously clean the eggs with their mouthparts to protect the eggs from pathogens [5], [31]–[33]. In a species of shield bug, Parastrachia japonensis (Hemiptera: Cydnidae), maternal care by provisioning increases nymphal survival under high-predation pressure environments [10], [34]. Female Anisolabis maritima (Dermaptera: Anisolabididae) bring food to the nest after their eggs hatch, and this behavior increases the survival of the nymphs [35].…”

Guarding behavior is an important activity in sub-social insects, and this behavior is believed to improve the survival of offspring. Sclerodermus harmandi (Hymenoptera: Bethylidae) is one of most powerful epizoic parasitoid wasps, and it parasitizes Monochamus alternatus, a borer of wood and also the primary vector of the pinewood nematode Bursaphelenchus xylophilus. After laying eggs, S. harmandi exhibits sub-social behavior involving the female tending the clutch of eggs until emergence (guarding behavior). In this study, the benefits of this maternal care with regard to improvements in the survival of offspring were examined. During the developmental stages, only offspring in the egg and larval stages were sensitive to guarding behavior. A positive relationship between the survival of the offspring and the duration of guarding was detected with logistic regression analysis. A female replacement experiment demonstrated that multiparous S. harmandi stepmothers showed guarding behavior and that this behavior improved the survival of the immature offspring, whereas nulliparous stepmothers failed to exhibit the guarding behavior. These results indicate that S. harmandi females display maternal care and that this behavior improves the survival of offspring.

“…Despite maternal provisioning of seeds (below), female parents may sometimes be unsuccessful in carrying sufficient numbers of seeds to support their nymphs and the nymphs may suffer a shortage of food. Nymphs independent of their mother have to forage for host seeds scattered on the ground, which would be costly for the nymphs (Filippi et al 2000). Selection presumably favours offspring possessing high mobility at independence from maternal care.…”

performance and rivalry in a sub-social bug. Á/ Oikos 107: 28 Á/35.Trophic eggs, which are inviable and usually function as a food supply for offspring, have been regarded as extended parental investment or the outcome of parent Á/ offspring conflict in sibling oophagy. Adomerus triguttulus (Heteroptera: Cydnidae) is a sub-social bug showing a complex pattern of maternal care, including progressive provisioning of host seeds and trophic-egg production. To investigate the functions of trophic eggs, we removed trophic eggs from clutches under different resource conditions. The longevity of nymphs was greatly extended by feeding upon trophic eggs when seeds were excluded. When seeds were provided, trophic-egg feeding by nymphs enhanced their development, but there were no significant effects on brood survival. Some viable eggs were also fed upon by sibling nymphs. However, there was no difference in the proportion of viable eggs consumed between clutches with and without trophic eggs. Females lay viable eggs within the first oviposition day. The synchronous hatching resulting from this oviposition mode seems to prevent sibcannibalism. The body size of females affected their relative investment in trophic eggs; larger females produced more viable eggs with relatively fewer trophic eggs. The functions and adaptive allocation of trophic eggs are discussed in light of the two hypotheses mentioned above.

“…Nymphs will suffer from predation pressure and starvation without mother attendance. Filippi et al (2000) demonstrated that in the sub-social shield bug, Parastrachia japonensis, progressive provisioning enhances nymphal survival in high predation-pressure environments by inhibiting nymphal dispersal from safe nesting sites. Staying in the nest decreases the risk of predation, and provisioning by the mother decreases the risk of starvation.…”

Progressive Provisioning by the Females of the Earwig,Anisolabis maritima, Increases the Survival Rate of the Young

Provisioning the young is an important form of insect parental care and is believed to improve the survival and growth of the young. Anisolabis maritima Bonelli (Dermaptera: Anisolabididae) is a cosmopolitan species of earwig that shows sub-social behavior in which the females tend clutches of eggs in soil burrows. The defensive and provisioning behaviors of these females were examined in this study. When disturbed, maternal individuals abandoned the nest less than non-maternal individuals. Females brought food to the nest after their eggs hatched, and the survival of the nymphs was increased by provisioning. Even when mothers were removed, providing food to the nymphs increased survival as well as when the nymphs were provisioned by the mother. These results show that A. maritima mothers provision the nymphs and that this provisioning improves their survival.
