13. Resistance to Anticarsia gemmatalis Hübner (Lepidoptera, Noctuidae) in transgenic soybean (Glycine max (L.) Merrill Fabales, Fabaceae) cultivar IAS5 expressing a modified Cry1Ac endotoxin
Somatic embryos of the commercial soybean (Glycine max) cultivar IAS5 were co-transformed using particle bombardment with a synthetic form of the Bacillus thuringiensis delta-endotoxin crystal protein gene cry1Ac, the beta-glucuronidase reporter gene gusA and the hygromycin resistance gene hpt. Hygromycin-resistant tissues were proliferated individually to g

14. Análise do efeito causado pelos genes quitinase e catepsina dos baculovírus CfDefNPV e AcMNPV inseridos no genoma do Anticarsia gemmatalis multiple nucleopolyhedrovirus
Baculoviruses are double-stranded DNA viruses, arthropod-specific that have been mainly used as biological-control agents of insect pests and as heterologous gene expression vectors. The use of the Anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV) in Brazil, for the control of the velvetbean caterpillar is the most successful example of a virus us

15. Bases biológicas para utilização de Trichogramma pretiosum Riley, 1879(Hymenoptera: Trichogrammatidae) para controle de Pseudoplusia includens (Walker, 1857) e Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae) em soja / Biological base for using Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae to control Pseudoplusia includens (Walker, 1857) and Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae) in soybean
Com o objetivo de avaliar o potencial de utilização de Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) no manejo de Pseudoplusia includens (Walker, 1857) e Anticarsia gemmatalis Hübner, 1818 (Lepidoptera: Noctuidae), foram realizados diferentes bioensaios incluindo seleção de linhagens, avaliação das características biológicas, c

16. Contribuição da microbiota bacteriana para o processo digestivo e desenvolvimento da lagarta da soja (Anticarsia gemmatalis) e caracterização de bactérias proteolíticas associadas ao seu trato intestinal / Contribution of the bacterial microbiota to the digestive process and development of velvetbean caterpillar (Anticarsia gemmatalis) and characterization of proteolytic bacteria associated with intestinal tract
Interações entre bactérias intestinais e insetos têm sido extensivamente estudadas em alguns sistemas, como cupins e afídeos. Entretanto, pouco é conhecido sobre a associação entre bactéria e Lepidoptera, uma das ordens que compreende os principais insetos fitófagos, responsáveis por grandes perdas na agricultura. Alguns autores acreditam que devi

17. Purificação parcial, propriedades e caracterização cinética de proteases tripsina-like do intestino médio da lagarta da soja, Anticarsia gemmatalis / Partial purification, properties and kinetics characterization of midgut trypsin-like proteases from the velvetbean caterpillar, Anticarsia gemmatalis
The identification and characterization of proteases from the insect midgut are of great importance for research and development pest resistant cultivars of crop species. Different processes of trypsin-like proteases purification from midgut A. gemmatalis and characterization of these proteases were carried out in this work. Two fractions were isolated durin

18. Perspectives of digestive pest control with proteinase inhibitors that mainly affect the trypsin-like activity of Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae)
The present study describes the main characteristics of the proteolytic activities of the velvetbean caterpillar, Anticarsia gemmatalis Hübner, and their sensitivity to proteinase inhibitors and activators. Midguts of last instar larvae reared on an artificial diet were homogenized in 0.15 M NaCl and centrifuged at 14,000 g for 10 min at 4ºC and the supern

19. Intraspecific variation and population structure of the Velvetbean Caterpillar, Anticarsia gemmatalis Hübner, 1818 (Insecta: Lepidoptera: Noctuidae)
The velvetbean caterpillar (VBC), Anticarsia gemmatalis Hübner, 1818 (Insecta: Lepidoptera: Noctuidae), is one of the most important New World soybean agro-ecosystems pests, occurring from 40° N in the USA to 39° S in Argentina. Information on the migration patterns of the VBC moth may be important for managing the resistance of VBC populations to insecti

20. Incidência natural e biologia de Trichogramma atopovirilia Oatman & Platner, 1983 (Hymenoptera, Trichogrammatidae) em ovos de Anticarsia gemmatalis Hübner, 1818 (Lepidoptera, Noctuidae)
Trichogramma atopovirilia Oatman & Platner is an egg parasitoid of the corn earworm Helicoverpa zea (Boddie) (Lepidoptera, Noctuidae), and has recently been collected from eggs of Anticarsia gemmatalis Hübner on soybeans. In order to evaluate the suitability of A. gemmatalis eggs as hosts of T. atopovirilia, field surveys were conducted in 1999 and 2000 on

22. Genetic transformation, recovery, and characterization of fertile soybean transgenic for a synthetic Bacillus thuringiensis cryIAc gene.
Somatic embryos of jack, a Glycine max (L.) Merrill cultivar, were transformed using microprojectile bombardment with a synthetic Bacillus thuringiensis insecticidal crystal protein gene (Bt cryIAc) driven by the 35S promoter and linked to the HPH gene. Approximately 10 g of tissue was bombarded, and three transgenic lines were selected on hygromycin-contain
