Thanatosis (death-feigning) has rarely been documented for Hymenoptera but occurs in the parasitoid wasp Nasonia vitripennis. The propensity to exhibit thanatosis did not differ with age, sex, or food deprivation. Squeezing a female’s abdomen and contacting her antennae were equally likely to trigger thanatosis. Dropping an object next to a female in order to cause substrate vibrations never triggered thanatosis, and dropping a female from a test tube rarely triggered thanatosis. Thanatosis was… 

Factors Affecting Thanatosis in the Braconid Parasitoid Wasp Heterospilus prosopidis

The effects of sex, age, temperature, and background color on thanatosis in the parasitoid wasp Heterospilus prosopidis under laboratory conditions are examined, and it is found that some of these factors have significant effects on moreatosis of this species.

Thanatosis in the freshwater crab Trichodactylus panoplus ( Decapoda : Brachyura : Trichodactylidae )

Thanatosis behavior was tested in 18 individuals of Trichodactylus panoplus, 10 males and 8 females, and found no significant influence of the size of an animal on the time that it remained still.

Thanatosis in freshwater anomurans (Decapoda: Aeglidae)

In the two species, thanatosis occurred in both light and dark photophase, and there was no significant difference in the duration of the events between the photophases.

On the Adult Behavioral Repertoire of the Sawfly Perreyia flavipes Konow, 1899 (Hymenoptera: Pergidae): Movement, Mating, and Thanatosis

The results show some unusual behavioral adaptations presented by P. flavipes, such as irregular activity behavior (i.e., deficient gait pattern), thanatosis behavior-like display, and primitive maternal care.

A Behavioral Syndrome in the Adzuki Bean Beetle: Genetic Correlation Among Death Feigning, Activity, and Mating Behavior

It is demonstrated that death feigning is genetically correlated to mating behavior in males but not females in this species, suggesting that behavioral correlations may not always reflect in the same way in both sexes.

Tonic Immobility Is Influenced by Starvation, Life Stage, and Body Mass in Ixodid Ticks

The identification and quantification of a novel antipredation strategy add a new component to the understanding of tick life history as ticks may become more aggressive in their search for a bloodmeal as they continue to starve.

Positive genetic correlations between life-history traits and death-feigning behavior in adzuki bean beetle (Callosobruchus chinensis)

Compared the life-history traits of individuals derived from two regimes artificially selected for the duration of death feigning in the adzuki bean beetle, Callosobruchus chinensis, the results provide the novel possibility that deathFeigning is a potentially advantageous anti-predator behavior that, through a positive genetic correlation with some life- history traits, can bring a higher fitness to an individual adopting this behavior.

A review of thanatosis (death feigning) as an anti-predator behaviour

It is demonstrated how apparently disparate observations in the recent literature can be synthesised through placing the behaviour within a cost-benefit framework in comparison to alternative behavioural choices, and how aspects of the ecology differentially affect costs and benefits.



Effects of Starvation on Death-Feigning in Adults of Cylas formicarius (Coleoptera: Brentidae)

Abstract Effects of starvation on death-feigning behavior, or thanatosis, were observed in adults of the sweetpotato weevil, Cylas formicarius (F.). A significantly lower proportion of death-feigned

Diurnal Periodicity of Death-Feigning in Cylas formicarius (Coleoptera: Brentidae)

The results suggest that, in general, death-feigning is less frequent in active weevils compared to inactive ones.

The Biology of the Parasitic Wasp Mormoniella vitripennis [=Nasonia brevicornis] (Walker)

The biology, economic importance, physiology, ecology, cytology, and genetics of the parasitic wasp, Mormoniella vitripennis (=Nasonia brevicornis), are reviewed, and its use and value in research

Dying or Illness Feigning: An Unreported Feeding Tactic of the Comb Grouper Mycteroperca acutirostris (Serranidae) from the Southwest Atlantic

Field observations on dying or illness feigning by the Comb Grouper Mycteroperca acutirostris in shallow waters of the southeastern Brazil's coast are reported, and comments on this unique hunting behavior, similar to death feigning previously recorded for a cichlid species in Africa.

Geographic and genetic variation in death-feigning behavior in the flour beetle,Tribolium castaneum

Five recently collected wild strains of the flour beetle were tested for phenotypic differences in the proclivity toward death feigning and in the duration of feints, indicating that simple additive genetic factors are involved in the transmission of this behavior.

The chalcidoid parasites of the common house or typhoid fly (|Musca domestica| Linn.) and its allies. ii. Reconstruction of the genus |Pachycrepoideus| Ashmead of the family Pteromalidae,

A monotypical genus which occurred but rarely in connection with its host, it is believed that it attacks Musca domestica as a primary parasite, with the possible alternative of being secondary, its host Muscidifurax raptor Girault and Sanders MS.

The cicada genus Nyara n. gen.(Homoptera Cicadidae):systematics, behaviour and conservation status

Nyara is the third endemic cicada genus described from a South African forest and its distribution along the subtropical Eastern Cape coast, which is threatened by strip mining and housing developments, highlights the need for conservation of these under-researched habitats.

Effects of Mating on Female Locomotor Activity in the Parasitoid Wasp Nasonia vitripennis (Hymenoptera: Pteromalidae)

Effect of mating status on locomotor activity was examined in females of the parasitoid wasp Nasonia vitripennis (Walker) and females that were more active subsequently killed more hosts, whereas this was not true for virgin females.

Defensive behaviour in Ghanaian praying mantids

The defensive behaviour of 25 species of praying mantids from Ghana is described and a curious “boxing display” is described, used as taxonomic evidence for the close relationship of these three genera.
