In long-lived social mammals such as primates, individuals can benefit from social bonds with close kin, including their mothers. In the patrilocal chimpanzee (Pan troglodytes spp.) and bonobo (Pan paniscus), sexually mature males reside and reproduce in their natal groups and can retain post-dependency bonds with their mothers, while immatures of both sexes might also have their paternal grand...

The ectoparasitic mite Pyemotes tritici (Lagrèze-Fossat & Montané) (Acari: Pyemotidae) caused paralysis and reduced longevity in eucalyptus longhorned borer, Phoracantha semipunctata F., under laboratory rearing conditions. Application of dusting sulfur to logs that contained pupating borers greatly reduced densities of mites on emerging adult beetles and increased beetle survivorship. Uniform ...

Four bed bug strains (Cimex lectularius) with different levels of pyrethroid resistance were evaluated to determine their ability to survive extended periods of starvation. First instar bed bugs of all strains were the most vulnerable to starvation (13.8-36.3 days mean survival time). Fifth instars and adults survived the longest during starvation (41.5-142.6 days). Significant differences in s...

background: this study aimed to examine the impact of ego-resilience and family function on quality of life in childhood leukemia survivors. methods: this study targeted 100 pediatric leukemia survivors, who visited the pediatric hemato-oncology center in south korea from aug to dec 2011. a structured questionnaire of ego-resilience, family function and quality of life used to collect data thro...

Larvae of the leaf beetle Eurypedus nigrosignatus Boheman carry fécula and cast skins on their dorsa forming a protective device, commonly called a fecal shield. Survival from egg to adult eclosión, natural enemies, and relation to its hostplant, Cordia curassavica (Jacq.) Roem. and Schult. (Boraginaceae) were assessed. Overall survival was 2%; eggs and fourth instars were less susceptible to e...

Comparative analysis of development and survivorship of two geographically divergent populations of the Natal fruit fly Ceratitis rosa Karsch designated as Ceratitis rosa R1 and Ceratitis rosa R2 from Kenya and South Africa were studied at seven constant temperatures (10, 15, 20, 25, 30, 33, 35 °C). Temperature range for development and survival of both populations was 15-35 °C. The development...

The effectiveness of inundative releases of the parasitoid Eretmocerus eremicus n. sp. Rose & Zolnerowich for control of Bemisia argentifolii Bellows & Perring on poinsettia in replicated experimental greenhouses was determined. We evaluated two release rates of E. eremicus: a low release rate (one female per plant per week, released in two greenhouses, in spring 1995) and a high release rate (...

We observed the survivorship and distribution of larvae and pupae of Anopheles gambiae s.l. Giles immature stages in three habitats (rock pools, swamp, and puddles) in Banambani village. Mali, West Africa, during the mid-rainy season of 2000. Horizontal life tables were constructed for immatures in the laboratory. Times spent in the various immature stages were determined, and laboratory surviv...

Host plant switching is common among phytophagous insects. Once optimal food sources have been depleted, immature insects may resort to use of suboptimal hosts in order to complete their development. Such host switching may have dramatic consequences for insect fitness. Here we investigate the effects of host switching in larvae of the viburnum leaf beetle, Pyrrhalta viburni, an invasive landsc...
