1. Efeito da resistência de Spodoptera frugiperda (J.E.Smith, 1797) (Lepidoptera: Noctuidae) a lambda-cyhalothrin na interação com o milho geneticamente modificado (MON810) e na resposta imunológica ao parasitismo por Campoletis af / Effect of resistance of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) to lambda-cyhalothrin on the interaction with genetically modified maize (MON810) and the immune response to parasitization by Campoletis aff. flavicincta (Hymenoptera: Ichneumonidae)
Fitness costs of insect resistance to insecticides can be exploited by integrating other pest control strategies in Integrated Pest Management (IPM) programs. The objective of this research was to evaluate the existence of fitness costs associated with the resistance of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) to the pyrethroid insecticid

2. Host quality of different aphid species for rearing Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae)
This study aimed to evaluate the quality of the aphid Myzus persicae (Sulzer), Lipaphis erysimi (Kaltenbach) and Brevicoryne brassicae (L.) as hosts for the parasitoid Diaeretiella rapae (McIntosh). Parasitization by D. rapae was higher on M. persicae than on L. erysimi and B. brassicae. The time of development of D. rapae from egg to mummy or egg to adult m

3. Influência da densidade de ovos de Diaphania hyalinata (L.) (Lepidoptera: Crambidae) na capacidade de parasitismo de Trichogramma exiguum Pinto & Platner e Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)
The effects of the egg density of Diaphania hyalinata (L.) on several biological parameters of Trichogramma exiguum Pinto & Platner and T. pretiosum Riley were investigated. For that, 24h-old egg masses were isolated in glass tubes (15 replicates; 1 egg mass = 1 replicate), and offered to parasitization by a newly-emerged female of T. pretiosum or T. exiguum

4. Effect of Trichopoda Pennipes parasitization on Nezara Viridula.
Trichopoda pennipes parasitization had a strong negative effect on Nezara viridula adult longevity, fecundity and feeding. A parasitized female lived half the time of an unparasitized one and for a parasitized male this reduction in longevity was even greater. Unparasitized females laid four times more eggs than parasitized one. Parasitization had no signifi

5. Aspects of Trichopoda Pennipes (Fabricius) (Diptera:Tachinidae) oviposition and its Relation To Parasitization on The Adults of Nezara Viridula (Linnaeus) (Heteroptera:Pentatomidae)
Eggs of Trichopoda pennipes were found on Nezara viridula host bodies at all sample sites. Supernumerary oviposition was found to be common on both male and female, and males had a higher incidence of tachinid eggs and more eggs/individual. Males consistently had higher parasitization levels. Tachinid eggs were found virtually on the whole body surface of Ne

6. Bioecologia de Spodoptera frugiperda e de seus parasitóides de ovos Telenomus remus, Trichogramma atopovirilia e T. pretiosum / Bioecology of Spodoptera frugiperda and of its egg parasitoids Telenomus remus, Trichogramma atopovirilia and T. pretiosum
Os seres vivos estão constantemente influenciando e sendo influenciados pelo meio ambiente. Esta interação pode afetar diretamente o comportamento e a sobrevivência destes seres vivos, incluindo os insetos. O objetivo deste trabalho foi descrever os efeitos de fatores bióticos e abióticos sobre o comportamento e sobrevivência de Spodoptera frugiperda

7. Selectivity of neem to Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis (Hymenoptera: Trichogrammatidae)
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.) (Lepidoptera: Elachistidae) and Hypocala andremona (Stoll) (Lepidoptera:

8. Primeiro relato de ocorrência de Telenomus podisi (Ashmead) e Trissolcus urichi (Crawford) (Hymenoptera : Scelionidae) como Parasitóides de ovos do Percevejo-do-Colmo-do-Arroz, Tibraca limbativentris (Stål) (Hemiptera: Pentatomidae), em Santa Catarina
We report the first occurrence of Telenomus podisi (Ashmead) and Trissolcus urichi (Crawford) parasitizing eggs of the Rice Stem Bug, Tibraca limbativentris (Stål), in Santa Catarina, Brazil. These species have a high potential of parasitization, pointing them as an alternative for biological control of T. limbativentris.

9. Parasitoides larva-pupa de Hylesia metabus Cramer (Lepidoptera: Saturniidae) en la región nororiental de Venezuela: un caso de control Biológico Natural
The moth Hylesia metabus Cramer is considered a public health pest due to the release of urticating hairs by adult females during periodic invasions of towns and villages, producing dermatits in humans. We reported natural parasitism levels for this moth during six life cycles in two localities in northeastern Venezuela. Pupae were collected in the field and

10. Seletividade de inseticidas reguladores de crescimento e de neonicotinÃides a Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) / Selectivity of insecticides growth regulators and neonicotinoids insecticides to Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae)
The effects of acetamiprid (0.05 g a.i./L), lufenuron (0.04 g a.i./L), imidacloprid (0.14 g a.i./L), novaluron (0.02 g a.i./L), triflumuron (0.14 g a.i./L) and pyriproxifen (0.1 g a.i./L) on the immature and adult stages of Trichogramma pretiosum Riley were evaluated. The work was divided in two bioassays. In the first one, eggs of Anagasta kuehniella (Zelle

11. Estudos Sobre os efeitos de um produto a base de Bacillus Thuringiensis var. Kurstaki em Ephestia Kuehniella (Zeller, 1879) (Lepidoptera: Pyralidade) e no seu Ectoparasitoide Bracon hebetor (Say, 1836) (Hymenoptera: Braconidae)
Ephestia kuehniella is a very important pest, attacking wheat flour in mills and stored places. Due to the negative impact of the chemical control methods, alternative agents are being studied to reach more safety and more satisfactory results. Some biological, physical and mechanical components should be adequate to be includes in integrated pest management

12. Cellular Immune Response to Parasitization in Drosophila Requires the EBF Orthologue Collier
Drosophila immune response involves three types of hemocytes (‘blood cells’). One cell type, the lamellocyte, is induced to differentiate only under particular conditions, such as parasitization by wasps. Here, we have investigated the mechanisms underlying the specification of lamellocytes. We first show that collier (col), the Drosophila orthologue of
