Telenomus podisi Parasitism on Dichelops melacanthus and Podisus nigrispinus Eggs at Different Temperatures [PDF]
Florida Entomologist, 2019 Dichelops melacanthus (Dallas) (Heteroptera: Pentatomidae) is the most important stink bug species that feeds on maize in South America, and it is frequently controlled with chemical pesticides. As an alternative, more sustainable management strategies can be applied, among which the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Scelionidae ...

Revista Brasileira De Entomologia, 2022 ABSTRACT This work aims to evaluate the toxicity of insecticides used for stink bug control to the egg parasitoids Telenomus podisi and Trissolcus teretis. We tested ethiprole and sulfoxaflor + lambda-cyhalothrin in comparison with thiamethoxam + lambda-cyhalothrin and chlorpyrifos.

This study investigates the influence of parasitoid age and egg age of the hosts Euschistus heros (Fabricius) and Dichelops melacanthus (Dallas) on parasitism of Telenomus podisi Ashmead. Six separate bioassays were conducted: parasitism on eggs of E. heros (bioassay 1) and D. melacanthus (bioassay 2) by T. podisi females of different age (1, 5, and 10

Successful biological control requires detailed knowledge about the mass rearing conditions of the control agents in order to ensure higher quality of field-released insects. Thus, we investigated whether rearing fluctuating thermal condition would affect the fitness and costs of the parasitoid wasp Telenomus podisi Ashmead (a biocontrol agent used for

Journal of Economic Entomology, 2015
Insecticide use remains controversial, and subjected to increasing environmental and health concerns, even when recent insecticide groups are considered. Neonicotinoids and even bioinsecticides are in the forefront of discussions regarding their nontarget safety.

The objective of this study was to evaluate possible side effects of insecticides used in soybean crops on pupae and adults of the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Platygastridae) under laboratory conditions. The protocol was adapted from standard methodology stablished by the Pesticides and Beneficial Organisms Working Group of ...

Telenomus podisi Ashmead and Trissolcus euschisti (Ashmead) are sympatric scelionid stink bug egg parasitoids whose intraspecific host discrimination is based on external post-ovipositional host egg markings. There is no interspecific host discrimination.

Phytoparasitica, 2018
Biological control of phytophagous bugs in soybean crops is efficiently performed by egg parasitoids, such as Telenomus podisi and Trissolcus basalis. Based on this, the use of agrochemicals in these crops must be managed consciously, making use of pesticides that are selective to the egg of these parasitoids, in order to ensure a balanced ecosystem ...
