ACTIVITY OF SOME BRAZILIAN ISOLATES OF ENTOMOPATHOGENIC FUNGI AGAINST THE POULTRY RED MITE DERMANYSSUS GALLINAE DE GEER (ACARI: DERMANYSSIDAE) Rev. Bras. Ciênc. Avic.
Kasburg,CR; Alves,LFA; Oliveira,DGP; Rohde,C.
ABSTRACT Poultry red mite Dermanyssus gallinae is a cosmopolitan and hematophagous species commonly found in layer houses around the world. Poultry mite infestations may cause anemia, stress, low body weight and egg production, and mortality. Mite control is typically based on chemical products, but they are not effective and leave residues in eggs; therefore, alternative control methods, such as entomopathogenic fungi, need to researched. This study aimed at evaluating, in the laboratory, the activity of Brazilian isolates of entomopathogenic fungi against D. gallinae. The mites were collected from a commercial layer house and were sprayed with conidial suspensions (1 × 108 conidia/mL) of five isolates of Beauveria bassiana and Metarhizium anisopliae. All...

Comparative bio-efficacy of nuclear polyhedrosis virus (NPV) and Spinosad against American bollwormm, Helicoverpa armigera (Hubner) Rev. Bras. entomol.
Nawaz,Ahmad; Ali,Habib; Sufyan,Muhammad; Gogi,Muhammad Dildar; Arif,Muhammad Jalal; Ranjha,Mazhar Hussain; Arshid,Muhammad; Waseem,Muhammad; Mustafa,Tariq; Qasim,Muhammad; Rizwan,Muhammad; Zaynab,Madiha; Khan,Khalid Ali; Ghramh,Hamed A..
ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different...

Compatibility between the entomopathogenic fungus Beauveria bassiana and insecticides used in coffee plantations Scientia Agricola
Oliveira,Carolina Natali de; Neves,Pedro Manuel Oliveira Janeiro; Kawazoe,Lídio Sueki.
Microbial control in integrated pest management (IPM) programs of coffee plantations is an important factor for the reduction of pest population densities. The use of selective pesticides can be associated with entomopathogens, increasing the efficiency of the control and reducing the use of required insecticides. The in vitro fungitoxic effect of insecticide formulations of Thiamethoxam, Cyfluthrin, Deltamethrin, Alpha-Cypermethrin, Triazophos, Chlorpyrifos, Fenpropathrin and Endosulfan and Beauveria bassiana (CG 425 strain) was evaluated at three concentrations (FR = average field recommendation; 0.5 ´ FR and 2 ´ FR). Effects of these products on conidia germination, vegetative growth and sporulation were compared. Only five insecticides, at the FR...

Differential susceptibility of adults and nymphs of Blattella germanica (L.) (Blattodea: Blattellidae) to infection by Metarhizium anisopliae and assessment of delivery strategies Neotropical Entomology
Lopes,RB; Alves,SB.
Microbial insecticides for cockroach control, such as those containing entomopathogenic fungi, may be an alternative to reduce contamination by chemicals in housing and food storage environments. Virulence of isolate ESALQ1037 belonging to the Metarhizium anisopliae complex against nymphs and adults of Blattella germanica (L.), and its infectivity following exposure of insects to a contaminated surface or to M. anisopliae-bait were determined under laboratory conditions. Estimated LD50 15 d following topical inoculation was 2.69 x 10(5) conidia per adult, whereas for nymphs the maximum mortality was lower than 50%. Baits amended with M. anisopliae conidia had no repellent effect on targets; adult mortality was inferior to 25%, and nymphs were not...

Estabilidade de uma formulação de Bacillus sphaericus armazenada sob diferentes temperaturas Scientia Agricola
Alves,Luis Francisco Angeli; Alves,Sérgio Batista; Lopes,Rogério Biaggioni; Augusto,Nílson Toschi.
O objetivo deste trabalho foi avaliar a estabilidade de uma formulação granulada de Bacillus sphaericus à base de sabugo de milho, armazenada em condições ambientais e a 50°C, tendo como comparação, uma suspensão concentrada de esporos e cristais da bactéria. A análise periódica dos materiais armazenados revelaram o efeito protetor da formulação sobre o microrganismo, de forma que ao longo de 12 meses de armazenamento, em condições ambiente, a viabilidade dos esporos foi maior que na suspensão concentrada. Além disso, a atividade inseticida para larvas de Culex quinquefasciatus, avaliada nos criadouros artificiais foi comparável ao patógeno não formulado. Quando mantidos a 50°C, a ação protetora da formulação mostrou-se mais eficiente, sendo que ao final...

Genetic variability of brazilian Alternaria spp. isolates as revealed by RAPD analysis BJM
Tigano,Myrian Silvana; Aljanabi,Salah; Mello,Sueli Corrêa Marques de.
The genetic variability of 22 isolates of the fungi Alternaria alternata and A. cassiae, obtained from Senna obtusifolia, was studied by RAPD analysis. A total of 491 scorable bands were produced with the use of 28 primers. Cluster analysis based on similarities computed from RAPD markers showed two distinct genetic groups of isolates related to both species. RAPD analysis proved to be an efficient method for detecting genetic variability of A. cassiae and A. alternata isolates occurring in S. obtusifolia, and also for distinguishing Alternaria species.
