“…Certainly, a significant amount of material is acquired by these predators when feeding on plants. For instance, male and female B. tabidus caged on cotton plant leaves can gain 24.6 ± 1.46 and 35.6 ± 2.04 mg (average ± SEM), respectively, which corresponds to approximately 28 and 30% of their body weight (Coelho et al 2009). The improvement of life history characteristics of the predator feeding on plants may be related to acquisition of amino acids and amides present in the apoplastic sap of the plant leaf, especially of those plants under increased nitrogenous fertilisation (Marschner 1995).…”

Zoophytophagous insects can feed on a variety of prey, plants and plant products. By studying the interactions between predatory hemipterans and plants harbouring the prey of these insects, scientists have started to establish two potential outcomes: (1) positive effects like the enhancement of their life history characteristics by acquiring plant contents; and (2) negative effects mediated by plant resistance to herbivores or prey ingesting secondary plant metabolites. Despite this research, there is a lack of information about the feeding sites of predatory hemipterans on their host plants, what they ingest from plants, and whether they cause damage to their host plants.The results presented here indicate that the xylem is one of the feeding sites of predatory hemipterans on plants. The dissection of predators that fed on plants with marked vessels and testing insects for the presence of Cry protein constitutively expressed in the cytoplasm of plant cells revealed that bugs are not able to acquire cytoplasm contents from the plant cell. In addition, we demonstrate that systemic insecticide circulating inside plants from soil applications contaminates these predators. Our results are discussed in the context of zoophytophagous feeding behaviour exhibited by predatory hemipterans and the use of systemic insecticides for the conservation of natural enemies. This interaction contradicts the concept of ecological selectivity obtained for natural enemies through the placement of systemic insecticide in the soil as a selective method of deploying chemical control and predatory hemipteran conservation within the integrated pest management framework.

“…With regard to the host plant, the predator B. tabidus showed no preference among the tested plants (Amaranthus lividus, Gossypium hirsutum and Phaseolus vulgaris), which favors its occurrence in different ecosystems using plants as a source of water and possibly nutrients (COELHO et al, 2009). …”

Studies of Asopinae predators in Brazil were initiated in the 1930's, focusing on the use of these insects in biological control programs. However, the beginning of a period of major contributions to the knowledge on Asopinae predators started in the year 1986, with the release of the first research results, in the Proceedings of the X Brazilian Congress of Entomology in Maceió, Alagoas, Brazil. In 1991 the first scientific paper was published on the predator Podisus connexivus Bergroth [= Podisus nigrispinus (Dallas)] (Hemiptera: Pentatomidae), with study of the biological parameters of this predator for alternative feeding of the caterpillars Bombyx mori Linnaeus (Lepidoptera: Bombycidae) and larvae Musca domestica (Linnaeus) (Diptera: Muscidae). The first master thesis studying Asopinae predators in Brazil was defended in 1990 at the Federal University of Lavras, which focused was on biology and predatory capacity of Podisus nigrolimbatus [= Brontocoris nigrolimbatus = Brontocoris tabidus] and Podisus connexivus [= Podisus nigrispinus] in the laboratory. Throughout all these years of research and investigations, advances with Asopinae predators occurred in several fields that resulted in a better understanding of these insects, making them an effective tool for controlling insect pests in the agriculture and forestry sectors.

“…They have carnivorous feeding habits, but may use their prey host plants as a supplement in their diet (COELHO et al, 2009;EVANGELISTA JÚNIOR et al, 2004). The phytophagy may promote the maintenance of these natural enemies in the field, regardless of the presence of the pest (HOLTZ et al, 2011).…”

ABSTRACT:Several studies have reported the importance of phytophagy in the history of life from predator stinkbugs. However, knowledge of the nutrients acquired by these insects, from plant materials, is scarce. The phytophagy studies of zoophytophagous predators benefit biological control programs, making them more effective, since the best resources may be offered to these insects, increasing the potential for predation and, thus obtaining, success in pest control. Thus, this study investigated the development and zoophytophagy of predator Podisus nigrispinus (Dallas) (Hemiptera: Pentatomidae) in eucalyptus seedlings, deficient in macronutrients. The experiment was conducted in a greenhouse and the treatments consisted of individual nitrogen omission, phosphorus, potassium, calcium, magnesium and sulfur nutrient solution, where the eucalyptus seedlings were being conducted. The pupae of Tenebrio molitor L. (Coleoptera: Teneobridae) were offered ad libitum. The results of this experiment demonstrated the importance of nutrition in plants for the development and predation of P. nigrispinus. The plants deficient in nitrogen and magnesium reduce the predation efficiency of this zoophytophagous. The omission of calcium, magnesium and sulfur adversely affected the development of this insect predator, extending its immature stages. The proper nutritional balance of the plants is essential for the success in biological control programs that use zoophytophagous predators.
