Cannibalism is commonly found among phytoseiids at almost all mobile life stages. The avoidance of kin cannibalism in the presence of non-kin has been observed in limited species of phytoseiids. Early experience with conspecifics can alter individuals’ social behaviour at later stages. In this study, we examined the influence of ontogenetic isolation on the cannibalism and kin recognition of the predatory mite Amblyseius herbicolus (Acari: Phytoseiidae). Using a choice test, A. herbicolus protonymphs, deutonymphs, pre-ovipositional adults, and ovipositional adults were used as predators, and larvae (siblings versus non-kin) were given as prey. Two rearing treatments were applied to the predators to generate different social experience during ontogeny: reared in isolation or in pairs with ad libitum mixed stages of Carpoglyphus lactis (Acari: Astigmata). The results showed that social experience with siblings during ontogeny significantly reduced the cannibalism rate. Despite the social experience during ontogeny, protonymphs, deutonymphs, and pre-ovipositional adults did not discriminate kin (siblings) from non-kin during cannibalism. Only adults during oviposition showed a preference to avoid cannibalising siblings when non-kin are available. The recognition mechanism of A. herbicolus may require the contact and assessment of their eggs during oviposition. Future studies can investigate if contact with non-kin eggs and subsequently hatching larvae can influence the discrimination ability of ovipositional adults. Whether A. herbicolus can avoid cannibalising familiar kin could also be examined.

“…There is evidence that social isolation can change gene expression [30] and induce epigenetic modifications [17,31]. The experience of social isolation also clearly affects fitness traits, for example by altering: mate choice and reproductive success [18,32], immunity or disease state [13,33], endocrine profiles [34,35], cooperative predator detection [36], communication [37], social competence [38], and the microbiome [39]. In a number of species, social isolation increases the likelihood of same-sex sexual behaviour (e.g.…”

“…The experience of social isolation by a focal organism therefore depends only partly on actual separation from conspecifics; the experience of social isolation and its attendant phenotypic effects can also arise from the inability to produce or receive such stimuli [35]. In addition, different modalities and types of social stimuli might not be equally important [68], and the timing of periods of isolation across the life course can determine its phenotypic outcome [69,38,49]. We suggest that social isolation can be measured phenotypically as an individual's deviation from a population-level optimum.…”

Social isolation has profound impacts. Most animal research focuses on negative phenotypic consequences of social isolation within individual lifetimes. Less is known about how it affects genetics, selection, and evolution over longer timescales, though ample indirect evidence suggests that it might. We advocate that evolutionary consequences of social isolation be tested more directly. We suggest that the 'index of social isolation', the mismatch between actual and optimal social interaction experienced by individuals within a population, may play a key role in releasing cryptic genetic variation, adaptation rates, diversification patterns, and ecosystem-level processes. Evolutionary dynamics arising from social isolation could have significant impacts in applied settings such as conservation, animal breeding, control of biological invasions, and evolutionary resilience to anthropogenic change.

“…Group living, at least early during life, has been described in numerous arthropod taxa, including butterflies (Allen, 2010; Tullberg & Hunter, 1996), beetles (Costa et al, 2007; Deneubourg et al, 1990), harvestmen (Machado et al, 2000), scorpions (Pandey et al, 2021), spiders (Lesne et al, 2016), and others. Laying eggs in batches can enhance fitness by allowing the mother to produce multiple offspring in a short period of time.…”

Sibling cannibalism in the false widow spider is dependent on spiderling density and the reliable availability of fresh prey

Adult female spiders lay batches of eggs in silken egg sacs, and after hatching, the spiderlings live for transient periods in their mother's web before dispersing. Sibling cannibalism is frequently observed among spiderlings of many species under conditions of food deprivation. Here, we conducted assays in small Petri dishes with different densities of newly hatched (second instar) spiderlings of the false widow spider, Steatoda grossa, using a split‐clutch design. Prey (freshly killed fruit flies) availability was manipulated both numerically and temporally. Offspring from 10 different females were separated as siblings into densities of two, four, or eight spiderlings per Petri dish and these were provided with either 0 flies (starvation control), two flies, four flies, or eight flies that were replenished weekly or every 3 weeks. A further control was conducted with solitary spiderlings in Petri dishes deprived of flies. The number of surviving spiderlings per Petri dish was counted every 3 days until only one remained (or until death of the solitary spiderling). Our results show that the rate of cannibalism was lower with increasing spiderling density and when fresh flies were replenished more frequently, whereas the number of flies that were provided did not affect cannibalism. In S. grossa, juvenile cannibalism occurs primarily under conditions of extreme food limitation, although in synanthropic habitats where the spider is abundant, it may be an adaptive strategy owing to the potential scarcity of prey. Under certain conditions, cannibalism in spiderlings is adaptive by eliminating competitors and providing nutrient‐rich food.
