This study presents the effect of a supplementary diet with amino acids and sodium chloride solutions in addition to prey on the development, survival and reproduction of the predator Podisus nigrispinus (Heteroptera, Pentatomidae). Both solutions showed deleterious effects on nymph survival, adult weight, female longevity, number of egg masses, eggs per female, eggs per egg mass and nymphs per female besides egg viability of P. nigrispinus when compared with diet with water and prey. When compared with plant supplements in the diet the use of amino acids and salt solutions for mass rearing of P. nigrispinus was inferior.

Abstract A method for rearing the southern green stinkbug, (Nezara viridula L.) (Heteroptera: Pentatomidae), using a modified lygus semi-solid artificial diet was developed. First to second-instar nymph were reared in a density of 631.5 ± 125.05 eggs per Petri-dish (4 cm deep × 15 cm diam). Second instar to adult were reared in a density of 535.0 ± 112.46 s instar nymphs per rearing cage (43 × 28 × 9 cm). Mating and oviposition occurred in popup rearing cages (30 × 30 cm), each holding 60–90 mixed sex adults of similar age. Adults emerged 35.88 ± 2.13 d after oviposition and survived for an average of 43.09 ± 9.53 d. On average, adults laid 223.95 ± 69.88 eggs in their lifetime, for a total production of 8,099 ± 1,277 fertile eggs/oviposition cage. Egg fertility was 77.93% ± 16.28. Egg masses held in petri-dishes had a total hatchability of 79.38% ± 20.03. Mortality of early nymphs in petri-dishes was 0.64% ± 0.12 for the first instar and 1.37% ± 0.45 for second instar. Late nymphal mortality in rearing cages was 1.41% ± 0.10, 3.47% ± 1.27, and 4.72% ± 1.29 for the third, fourth, and fifth instars, respectively. Survivorship from nymphs to adults was 88.48% ± 2.76. Using artificial diet for rearing N. viridula could reduce cost by avoiding time-consuming issues with daily feeding fresh natural hosts and insect manipulation. It could increase reliability and simplicity of bug production, which should facilitate mass rearing of its biological control agents.

Development and reproductive performance of Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) fed with Musca domestica L. (Diptera: Muscidae) larvae was evaluated. Duration of the nymphal phase of this predator was 31.2 days, with a 44.1% survival rate. Preoviposition and egg incubation periods and number of eggs/egg mass were 8.14 days, 5.6 days, and 45.4, respectively. B. tabidus presented 44.7% egg viability. Female longevity of this predator was 18.4 days. Results are discussed based on this prey use in mass rearing and maintenance of colonies of B. tabidus under laboratory conditions.

The objective of this work was to determine the fecundity of the predator Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) females of two weight classes aiming to define, which one presented higher productivity in the laboratory. Males and females of B. tabidus were reared from nymphs fed with Tenebrio molitor L. (Coleoptera: Tenebrionidae) pupae in laboratory. Females of B. tabidus weighting 95 to 150 mg and those with 160 to 220 mg constituted two treatments. Oviposition period and numbers of egg masses, eggs and nymphs per female of B. tabidus were higher in the treatment with heavier females, while the periods of preoviposition, between egg mass laying, egg incubation and number of eggs per egg mass, besides the percentage of nymphs hatched and adult longevity were similar between treatments. Heavier females of B. tabidus presented better productivity and for this reason they should be used in programs of mass rearing this predator.

AbstractThelytokous Wolbachia-infected Trichogramma spp. are widely used egg parasitoids against lepidopteran pests in biological control programs. Wolbachia may manipulate host wasps for superparasitism and is sensitive to temperature. To explore effects of temperature and superparasitism, we compared fitness parameters and Wolbachia-mediated phenotype of thelytokous Wolbachia-infected Trichogramma dendrolimi between those emerging from superparasitised or single-parasitised hosts at 17, 21, 25, or 29 °C. Infected mothers of T. dendrolimi showed reduced superparasitism and parasitism increased with temperature. Wolbachia titre decreased with temperature when females emerged from singly-parasitised hosts, but there was no correlation in superparasitised hosts. Females showed higher Wolbachia titres at 21, 25, or 29 °C when developing from superparasitised hosts. The daily male ratio of offspring increased with temperature, and the day-age threshold for 5%, 50%, or 95% daily male ratio decreased with temperature in both parasitism forms. Females that emerged from superparasitised hosts had a shorter life span and reduced fecundity. These results indicate that Wolbachia may affect host behaviour by increasing superparasitism to enhance its spread, but this has negative effects on thelytokous Wolbachia-infected T. dendrolimi.

Temperature and host stage are important factors that determine the successful development of parasitoids.Aenasius bambawaleiHayat (Hymenoptera: Encyrtidae) is a primary parasitoid of the newly invasive mealybug,Phenacoccus solenopsisTinsley (Hemiptera: Pseudococcidae). The effects of temperature on the parasitic characteristics ofA. bambawaleihave seldom been investigated. In the study, we explored the effects of temperature, exposure time, and host stage on the parasitization rate and offspring sex ratio (female to male) ofA. bambawaleiunder laboratory conditions. The laboratory results showed that the successful parasitization rate ofA. bambawaleiincreased with higher temperatures and older host stages. When the parasitoids were exposed to 36 °C for 24 h, the parasitization rate of female adults (52%) was nearly two times that of 3rd instar nymphs. Additionally, heat stress duration and host stage resulted in an increase in the offspring sex ratio ofA. bambawalei. WhenA. bambawaleiwas exposed to 36 °C for 24 h, the offspring sex ratio increased dramatically to 81.78% compared with those exposed for 12 h, and it increased to 45.34% compared with those exposed for 16 h. The offspring sex ratio was clearly higher when the host stage was an adult female mealybug Our findings provide important guidance for the mass rearing and field releases ofA. bambawaleifor the management ofP. solenopsisin the future.

In this study, Stomoxys species (S. calcitrans, S. sitiens and S. indica) were examined to improve on the current technique for mass rearing using a method of combined incubation parameters. Moreover, the reproductive potential of immature forms at various stages of development was defined. Immature forms of stable flies were incubated according to species. There was no significant difference in the number of immature forms obtained among species incubated under the same conditions. Six incubation parameters were used in combination, at temperatures (T) of 32°C, 27°C and 22°C and relative humidity (RH) of 90% and 70% RH. The combined method resulted in a higher number of eggs hatching at 32°C and 90% humidity as well as an increase in the number of larva pupated and emergence of imago at 27°C and 70% humidity.
