1. Effect of entomopathogens on Africanized Apis mellifera L. (Hymenoptera: Apidae)
ABSTRACT This study aimed to evaluate the effect of commercially used entomopathogens on Africanized Apis mellifera L. (Hymenoptera: Apidae). Four bioassays were performed: 1) pulverized entomopathogens on A. mellifera; 2) entomopathogens sprayed on a smooth surface; 3) entomopathogens sprayed on soy leaves; and 4) entomopathogens mixed with candy paste (sug

2. 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

3. Biologia e controle microbiano de Urbanus acawoios (Williams, 1926) (Lepidoptera: Hesperiidae): II. patologia e susceptibilidade em larvas infectadas por Bacillus thuringiensis Var. kurstaki (H-3a:3b)
Devido à falta de informações sobre Urbanus acawoios (Williams, 1926) (Lepidoptera: Hesperiidae), e pelos danos severos por ele causados em árvores de Clitoria racemosa, o presente trabalho foi desenvolvido sob condições de laboratório para verificar a possibilidade de utilizar Bacillus thuringiensis var. kurstaki (H-3a:3b) como agente microbiano para

4. Analise do efeito da radiação de microondas sobre Anagasta Kuhniella Zeller (1879) (Lepidoptera: Pyralidae) e seus dois agentes de controle biologico, Bracon hebertor (Say, 1836) (Hymenoptera: Braconidae) e Bacillus thuringiensis var. kurstaki (H:3a3b)
The application of Integrated Pest Management (IPM) means the utilization of efficient control methods which are ecologically safe and economicaly viable. Therefore, it is extremaly important to gather more information about the possible interactions between the different control agents, aimimg to optimize such a method. Microwaves (300 a 300.000 MHz), as we

5. Estudos biologicos e patologicos de dois piralideos pragas de produtos armazenados
O presente trabalho teve por objetivo estudos biológicos e patológicos de duas espécies de lepidópteros da família Pyralidae, pragas de produtos agrícolas armazenados. A biologia de Anagasta kuhniella (Zeller. 1879) e Plodia interpunctella (Hubner, 1813) foi estudada sob condições de 25 + ou 2 GRAUS C, 70 + ou - 10% U.R e 12 horas de fotofase. As lar

6. Cloning and Expression of an Insecticidal k-73 Type Crystal Protein Gene from Bacillus thuringiensis var. kurstaki into Escherichia coli
A 75-kilobase plasmid from Bacillus thuringiensis var. kurstaki (HD-244) was associated with the k-73 type insecticidal crystal protein production by mating into B. cereus and subsequent curing of excess plasmids. This plasmid was partially digested with endonuclease R · Sau3A and the fragments were cloned into Escherichia coli (HB101) on vector pBR322. Can

7. Cloning and expression of the Bacillus thuringiensis crystal protein gene in Escherichia coli.
Sau 3A1 partial digestion fragments from Bacillus thuringiensis var. kurstaki HD-1 plasmid DNA were ligated into the BamHI site of the cloning vector pBR322 and transformed into Escherichia coli strain HB101. Colonies presumed to contain recombinant plasmids were screened for production of an antigen that would react with antibody made against B. thuringiens
