“…Such high density in R. tristis is likely to be the result of its local association with Stylosanthes, common but highly patchily aggregated across Africa. It is interesting to note that the only two other known paternal species of Rhinocoris (and, indeed, of assassin bug) were also found at high densities on Stylosanthes in Uganda: R. albopilosus (8.7 ± 0.5 individuals in 20 m 2 ; n = 5) at Kabanyolo (Thomas, 1994), Kawanda (Odhiambo, 1959) and also at NAARI (Gilbert & Manica, 2009); and R. albopunctatus, found 'in large numbers' on and near S. gracilis at Serere Agricultural Research Station near Soroti (Nyiira, 1970). All three paternal species of Rhinocoris are morphologically almost indistinguishable.…”

“…First, guarding male assassin bugs are static for long periods and very reluctant to leave eggs, even when attacked by large enemies such as an ecologist (see e.g. Odhiambo, 1959;Nyiira, 1970). Second, guarding males may also have been more conspicuous to enemies than non-guarding males, given that guarding males were usually found on exposed Stylosanthes stems rather than concealed within low-lying vegetation as was typical for non-guarding males.…”

“…Occurrence of male-caring Rhinocoris, including R. tristis, is locally loosely associated with patches of the leguminous crop Stylosanthes where the bugs occur at reportedly high density (Odhiambo, 1959;Nyiira, 1970;Thomas, 1994). In R. tristis, males guard eggs and are simultaneously polygynous (Manica & Johnstone, 2004), mating and receiving batches from multiple females.…”

1. Which sex should care for offspring depends on the cost and benefits of the behaviour for each sex. Understanding these differences between the sexes is a fundamental step to explain the evolution of animal societies, but it is often difficult to quantify them empirically. A possible approach is to investigate two closely related species that perform a very similar type of care but in which the caring sex differs.2. Using field and laboratory data, we estimated the benefits and costs of parental care in two species of assassin bugs with very similar ecologies: Rhinocoris tristis, which has exclusive paternal care, and Rhinocoris carmelita, which has exclusive maternal care.3. In both species, the main benefit of care was a reduction in parasitism and predation of eggs. Guarding R. tristis males consumed eggs (filial cannibalism), and thus managed not to lose weight, but R. carmelita females paid the full energetic cost of care. Guarding male R. tristis incurred survival costs relative to non-guarding male and female conspecifics.4. Very high population density and female preference for males already guarding eggs (a preference previously recorded in fish) minimised the promiscuity cost of paternal care in R. tristis, explaining the difference in care pattern between the two species.

“…The most elaborate ovipositional behaviour is exhibited by species of Harpactorinae and this is known for a large number of forms (Kershaw 1909;Muller 1937;Cheriyan and Kylasam 1939;Bose 1951;Wallace 1953;Miller 1953Miller , 1971Odhiambo 1959;Edwards 1962Edwards , 1966Parker 1969;Nyiira 1970;Swadner and Yonke 1973a, b). The gravid females of Rhinocoris marqinatus, Sycanus collaris and Sphedanolestes bowringi Distant attach a cluster oflarge number of eggs on the under surface of big boulders, or on the stems of trees and plants.…”

Feeding and ovipositional behaviour in some reduviids (Insecta-Heteroptera)

Feeding behavioural studies of many exclusivelypredatory species exhibit c1earcut stimuli-response mediated sequences and these can be categorised into distinct sub-units like: search and location of prey ....approach and attack: of prey ....immobilisation of prey ....transportation of prey to safe place ....consumption of prey. These feeding behavioural activities differ among reduviids particularly with respect to prey types. These bugs are endowed with many structural, physiological and behavioural adaptations for efficient predation.The ovipositional behaviour of reduviids in different habitats also shows considerable variation and their reproductive strategies include selection of suitable sites to assure successful emergence and development of young ones and so far very few egg predators and egg parasites have been reported for these terrestrial insects.

“…Reduviids are the abundant predatory fauna in cotton fields (NYIRRA, 1970;FADARE, 1978;ABLES, 1978;HAFEZ et al, 1979;ANONYMOUS, 1986;SCHAEFER and AHMAD, 1987;ROSENHEIM and WILHOIT, 1993;SINGH et al, 1997). AMBROSE (1988) and SCHAEFER (1988) emphasized the biocontrol potential of reduviids and suggested that reduviids should be more seriously considered when developing biological control programmes.…”

Mass‐reared reduviid, Rhynocoris marginatus was released in large‐sized cotton field cages against three cotton pests, Spodoptera litura, Mylabris pustulata and Dysdercus cingulatus. Pest species were introduced into separate cages in the absence of other pests, parasitoids and predators. Control experimental cages without R. marginatus were maintained for each prey set up during the evaluation period. R. marginatus greatly reduced the infestation of S. litura (57.5%), M. pustulata (52.3%) and D. cingulatus (45.8%). The leaves, flower and boll damages (32%, 35% and 28% by S. litura, M. pustulata and D. cingulatus, respectively) and seed‐cotton yield loss (1.4, 1.6 and 1.25 times in S. litura, M. pustulata and D. cingulatus infested cages, respectively) were reduced by R. marginatus compared with such fields without R. marginatus. The field observations suggest this predator’s pest suppression and damage reduction efficacy.
