PARASITISM: The condition of living in or on another organism With or without D. gelechiidivoris, N. tenuis host larval feeding was generally low (0.61 0.2 larvae in 24 h) and not significant (GLM, 2 = 70.852, df = 11, p = 0.910) (Figure 1). After being exposed to the natural enemies, the infested leaflets were detached from the plant and the petioles were inserted into a moistened cotton wool ball to prevent early wilting. females are diploid, but males (where they occur, in arrhenotoky, PREDATORY: Living by preying on others (adjective) [synonym Previous studies reporting interactions between idiobiont larval ectoparasitoids and generalist omnivorous mirid predators for the control of T. absoluta have indicated that, even though idiobiont larval ectoparasitoids suffer intraguild predation by mirid predators [10], the outcome is not always negative for the control of the target pest.

Similarly, no significant differences were recorded in the number of D. gelechiidivoris females that eclosed in each of the treatments (F9,50 = 0.32, p = 0.966) (Figure 3). In summary, augmentative releases of N. tenuis and D. gelechiidivoris could potentially help reduce the infestation levels of T. absoluta because, in a tomato agroecosystem, all host life stages of the pest usually occur, albeit in varying densities, thus indicating that the host life-stage preferred by each natural enemy would always be present, thereby limiting the outcome of predation on D. gelechiidivoris-parasitized T. absoluta larvae.

However, owing to its ability to rapidly evolve resistance to most insecticides as well as the deleterious ecological consequences associated with excessive use of synthetic insecticides [24], biological control encompassing the use of parasitoids, predators, and pathogens has been recommended, albeit in conjunction with other control methods [19,21,23,25]. This is exemplified by the combine use of N. tenuis and the idiobiont larval ectoparasitoid Necremus tutae (Walker) (Hymenoptera: Eulophidae); the combined use of both natural enemies reduced the population of T. absolua in greenhouses more than either of the two used alone [38]. all die because the resources are too few [this is superparasitoidism].

Nesidiocoris tenuis did not discriminate between parasitized and unparasitized T. absoluta larvae. Several indigenous natural enemies such as the larval parasitoids: Bracon nigricans Szpligeti (Hymenoptera: Braconidae), Dolichogenidea appellater (Telenga) (Hymenoptera: Braconidae), Necremnus tutae Ribes, and Bernardo (Hymenoptera: Eulophidae); as well as the egg parasitoids: Trichogramma bourarachae Pintureau and Babault, Trichogramma cacoeciae (Marchal) (Hymenoptera: Trichogrammatidae); and the egg predators: M. pygmaeus, N. tenuis, and Rhynocoris segmentarius (Germar) (Hemiptera: Reduvidae), have been reported as biological control agents of T. absoluta in several African countries [19,37,51]. New batches of plants with first and second instar larvae were provided to the wasps every 48 h. Thereafter, plants exposed to parasitism were incubated with addition of healthy tomato plants to ensure better development of the parasitized larvae until emergence of adults. Finally, interactions may be antagonisticwhen the combined efficiency of two natural enemies is significantly less than the most effective species alone, resulting from adverse intraguild interactions [8,9]. from elsewhere].2. Idiobiont endoparasitism is postulated as having arisen amongst ectoparasitoids attacking cocooned hosts, as an adaptation that allows them to exploit pupae and puparia in relatively exposed positions; it is a fairly common strategy in the Ichneumonidae, but virtually unknown in the Braconidae. within the host and they all survive but produce adults of subnormal Dolichogenidea gelechiidivoris is native to Peru, Colombia, Chile, and Spain [30,31].

Note that T11: four N. tenuis adults alone with a tomato leaflet with 20 first instar larvae, served as control for mortality owing to feeding by N. tenuis; while T12: a tomato leaflet with 20 T. absoluta first instar larvae without the natural enemies, served as control for Tuta absoluta larval natural mortality. When both natural enemies were combined, the efficacy in reducing T. absoluta populations was significantly higher than that of either natural enemy used alone. it was for years interpreted by lawyers to mean an organism higher because no other suitable host/prey occurs in that area. The findings further contribute to data supporting the release of D. gelechiidivoris in tomato agroecosystems for the control of T. absoluta in Africa, where N. tenuis is widespread and abundant.

We established the significance of the model using analysis of deviance (with Chi-square test). The term 'idiobiont' refers to those parasitoid species that permanently paralyse their hosts during parasitism, causing the cessation of host growth and development. Koinobiont parasitoids attack hosts that continue feeding and growing during parasitism, whereas idiobiont parasitoids attack non-growing host stages or paralyzed hosts. Ent.
