Pupae of Trissolcus basalis (Wollaston) and Telenomus podisi Ashmead (Hymenoptera: Scelionidae) were stored at 12ºC and 15ºC for 120-210 days, after different periods of parasitism at 18ºC in order to evaluate adult emergence, longevity and ovipositional capacity. There was no emergence of adults at 12ºC. The rate of emergence of parasitoids transferred to 15ºC at the beginning of the pupal stage was 1.5% and 26.3%, for T. basalis and T. podisi respectively, whereas those parasitoids transferred one day before the expected date of emergence at 18ºC showed 86.4% of emergence for T. basalis and 59.9% for T. podisi. Mean adult longevity was also significantly lower when pupae were transferred to 15ºC at the beginning of the pupal stage. Females emerged after storage and maintained for 120 to 210 days at 15ºC parasitized host eggs after transference to 25ºC; however, fecundity of T. podisi was reduced in about 80% after cold storage.

Abstract The life cycle of stink bug, Glyphepomis dubia and the development of two egg parasitoids (Telenomus podisi and Trissolcus basalis) were studied at the Federal University of Maranhão, at 26 ± 2oC, relative humidity (RH) of 60 ± 10% and 12h photophase. Individuals used in the study were collected from seven rice fields located around the municipality of Arari, Maranhão, Brazil, and maintained in greenhouse and laboratory for the life cycle studies. From egg to adult, G. dubia took 35.2 days to complete the life cycle. The oviposition period was 37 days, with egg masses of about 12 eggs each and viability of 93.1%. Longevity was 53 and 65 days for females and males, respectively. The egg parasitoids Te. podisi and Tr. basalis parasitized and developed in G. dubia eggs; however, the biological characteristics of Tr. basalis were affected. Emergence of the parasitoids was higher for Te. podisi (83.5%) compared to the records for Tr. basalis (50.4%). Therefore, G. dubia may potentially achieve a pest status and Te. podisi is a promising biological control agent for G. dubia management in Brazil due to its higher longevity and better reproductive parameters.

ABSTRACT The use of pesticides in the soybean crop may impair the biological control, if the products are not selective to Telenomus podisi and Trissolcus basalis, which are important stink bug egg parasitoids. This study aimed to assess the selectivity of 15 pesticides registered for soybean crop on adults of T. podisi and T. basalis. Three laboratory bioassays were performed, totaling 18 treatments, in a completely randomized design, with four replications. The insecticides (g or mL of a.i.) imidacloprid + beta-cyfluthrin (0.25 + 0.03), deltamethrin (0.06), thiamethoxam + lambda-cyhalothrin (0.27 + 0.35), acephate (1.87) and fenitrothion (1.25) are harmful to both parasitoids species. Flubendiamide (1.20), diflubenzuron (2.00), Bacillus thuringiensis (0.08) and lufenuron (0.12) are innocuous to both parasitoids. The fungicides azoxystrobin + flutriafol (0.31 + 0.31), trifloxystrobin + prothioconazole (0.37 + 0.44), pyraclostrobin + metconazole (0.33 + 0.12) and trifloxystrobin + cyproconazole (0.94 + 0.40) are innocuous to T. podisi, but slightly harmful to T. basalis. The herbicides glufosinate ammonium salt (0.50) and glyphosate isopropylamine salt (1.20) are innocuous to both parasitoids.

Material Information

The history of Nezara viridula egg parasitoid introductions into Australia is critically reviewed. Using largely unpublished file material information is presented on the source of parasitoids, specific identification of parasitoids, numbers of parasitoids reared and released, and establishment and effects in the field. At least four species of egg parasitoids, in three genera, have been introduced and liberated into Australia since biological control efforts were first begun in 1933. There are records of 11 introductions involving Trissolcus basalis (Wollaston) (Egypt 1933; West Indies 1952-53; South Africa 1980; Brazil 1980; U.S.A. 1979-8 l), Trissolcus mitsukurii (Ashmead) (Japan l962), Ooencyrtus submetallicus (Howard) (West Indies 1952-53), and Telenomus chloropus (Thomson) (Japan 1962; Japan via U.S.A. 1980). Doubt is cast on the specific status of introductions from Italy (1956) and Pakistan (1 961), which are recorded in the literature as T, basalis. Evidence is presented that there is currently not enough information available to determine the specific classifications of these importations. Three programs in which Australian field populations of Trissolcus were bred and released elsewhere in Australia are also recorded. Post-release evaluation of introduced N. viridula egg parasitoids in Australia is reviewed. It is proposed that there is only circumstantial evidence to support the claim that N. viridula is under 'good' biological control by T. basalis in Australia. Areas of investigation that are of the most significance to current workers in N. viridula biological control are highlighted in the discussion.

First record of egg parasitoids of Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) in rice in Maranhão, Brazil  This is the first report of the species Trissolcus urichi (Crawford, 1913) and Telenomus podisi Ashmead, 1893 (Hymenoptera: Platygastridae) parasitizing Oebalus poecilus (Dallas, 1851) (Hemiptera: Pentatomidae) eggs in rice in Maranhão, Brazil. These parasitoids were collected in the municipality of Itapecuru Mirim, MA, in an area of 0.2 ha cultivated with rice. The eggs collected exhibited an average parasitism of 11.4%. Twenty egg parasitoids were collected and identified, these being one Tr. urichi and nineteen Te. podisi. The presence of these naturally occurring parasitoids in the field opens perspectives for updating the species of parasitoids that parasitize pentatomid eggs in rice fields in Brazil.
