“…The of 5.74 x 10 -1 ppb dose of permethrin stimulated population increase in S. cincticeps with higher R 0 (18.31 females/ female), RV x (33.85) and lower T (57.93 days) values, which indicate the occurrence of hormesis with this sublethal dose of permethrin (Calabrese, 1999;Forbes, 2000, Zanuncio, et al, 2003 and GRR of 40.80 females per female. The R0 supplies more precise values than the GRR because it incorporates mortality rate during young and adult stages of organisms (Force and Messenger, 1964).…”

“…Sublethal doses of insecticides that are toxic at high levels may increase the performance of organisms, a process known as hormesis (Calabrese and Baldwin, 1997a,b;Calabrese, 1999;Forbes, 2000), as reported for insects and mites of economic importance (Calabrese, 1999;Forbes, 2000) and for natural enemies (Zanuncio et al, 2003).…”

The stinkbug Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) can be found in agricultural and forest ecosystems feeding primarily on larvae of Coleoptera and Lepidoptera, where it can be exposed to insecticide applications. This study therefore aimed to evaluate the reproductive potential of'S. cincticeps after exposition to sublethal doses of permethrin (5.74 x 10 -3 , 5.74 x 10 -2 , 5.74 x 10 -1 , 5.74 and 57.44 ppb) through the use of a fertility life table. The development cycle of this predator was determined in order to calculate its net reproductive rate (R 0 ), the infinitesimal (r m ) and finite (λ) rates of increase in addition to mean generation time (T). The net reproductive (18.31), infinitesimal (r m ) (0.050) and finite (λ) (1.051) rates of increase were higher, while generation time (57.93 days) was shorter for S. cincticeps exposed to 5.74x10 -1 ppb of permethrin than in the control. This indicates a higher rate of population increase of this predator when exposed to this permethrin dose.

Trichogramma spp. (Hymenoptera: Trichogrammatidae) can control Diaphania hyalinata Linnaeus (Lepidoptera: Pyralidae). On the other hand, pesticides may reduce the efficiency of natural enemies. The objective was to evaluate the side-effects of fungicides used in the production of cucurbitaceous crops on Trichogramma atopovirilia Oatman & Platner parasitizing D. hyalinata eggs. The fungicides used in bioassays were: azoxystrobin (0.08 g active ingredient) and thiophanate-methyl (0.49 g ai L -1 ). Cardboards with 30 D. hyalinata eggs previously immersed in fungicide solutions and distilled water (control) were offered separately to 20 newly emerged T. atopovirilia females in glass tubes. Parasitism, parasitism reduction, emergence, sex ratio, and number of individuals per egg were evaluated. The fungicides chlorothalonil, thiophanate-methyl and tebuconazole reduced parasitism of T. atopovirilia by 43.37, 27.64 and 18.51%, respectively. However, parasitism with azoxystrobin (79.21%) was higher than the control (67.37%) (P ≤ 0.05). Chlorothalonil, thiophanate-methyl and tebuconazole reduced emergence by 73.77, 75.62 and 79.35% (P ≤ 0.05), respectively. Azoxystrobin and thiophanate-methyl reduced the sex ratio by 0.77 and 0.76 (P ≤ 0.05), respectively. Fungicides did not reduce the number of individuals per egg. The fungicides azoxystrobin and mancozeb were selective for T. atopovirilia for most studied parameters suggesting that these products must have the priority in crop disease management to allow efficient biological control of T. atopovirilia against D. hyalinata.

“…From this work, the main segment of research sought to determine aspects associated with effects of insecticides on the predator (CASTRO et al, 2012;PEREIRA et al, 2009;PICANÇO et al, 1997;TORRES;RUBERSON, 2004;TORRES et al, 2003;ZANUNCIO et al, 2003;1993b), which can be regarded as basic research, since from these results other studies with wider applicability were initiated. These include studies on selectivity of insecticides, which aim to understand compounds with toxicological effect on pests, but which preserve the natural enemy (GONRING et al, 2003;SUINAGA et al, 1996;TORRES, 2012;ZANUNCIO et al, 1998).…”

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.
