Entomopathogenic nematodes for the control of phorid and sciarid flies in mushroom crops PAB
Navarro,María Jesús; Gea,Francisco José.
The objective of this work was to evaluate the efficacy of two nematodes, Steinernema feltiae and S. carpocapsae, to control mushroom flies and to evaluate the effect of these treatments on Agaricus bisporus production. Two mushroom cultivation trials were carried out in controlled conditions, in substrate previously infested with the diptera Megaselia halterata and Lycoriella auripila, with two treatments: 106infective juveniles (IJ) per square meter of S. feltiae and 0.5x106IJ m-2S. feltiae + 0.5x106IJ m-2S. carpocapsae. Another experiment was carried out using the same treatments to evaluate the possible nematode effect on mushroom yield. The number of adults emerging from the substrate was evaluated for each fly species. No decrease in the population...

Analysis of biological parameters of Boophilus microplus Canestrini, 1887 exposed to entomopathogenic nematodes Steinernema carpocapsae Santa Rosa and All strains (Steinernema: Rhabditida) BABT
Freitas-Ribeiro,Gláucia Marques; Furlong,John; Vasconcelos,Viviane Oliveira; Dolinski,Cláudia; Loures-Ribeiro,Alan.
Engorged and partially engorged females of Boophilus microplus were exposed to 600; 3,000; 6,000 and 30,000 infective juveniles of Steinernema carpocapsae Weiser, 1955 Santa Rosa and All strains per dish, under lab conditions. Eggs weight, pre-laying period, laying period, survival period, reproductive efficiency rate, percentage of larval eclosion and lethal concentrations of 50% and 90% (CL50 and CL90) were calculated for engorged females. In the case of partially engorged females, only egg weight, survival period and CL50 and CL90 were calculated. All biological parameters of engorged or partially engorged females were altered by exposition of S. carpocapsae infective juveniles (IJs), Santa Rosa and All strains (p<0.05). The increase in the response...

Effect of the inoculum size on the axenic in vitro production of Steinernema carpocapsae Ciencia e Investigación Agraria
Suárez-Sánchez,Juan; Alatorre-Rosas,Raquel; Poggi-Varaldo,Héctor M; Barrera-Cortés,Josefina.
The effect of inoculum size on the axenic in vitro production of Steinernema carpocapsae, using a transparent medium with hemoglobin and cholesterol, was studied. Axenic cultivation was performed with fertile eggs ofS. carpocapsae (hatching of eggs: 89 ± 4%), which were obtained by lyses of female nematodes and subsequent incubation. Two important aspects of this work include the use of a completely transparent medium enriched with hemoglobin and cholesterol and the high multiplication factor of the population (MFIP) of 87, which is considered high for in vitro axenic cultures of nematodes. In vivo methods have the advantage of high MFIP, but they also have the disadvantage of the high number and complexity of the operations involved for the purposes of...

Virulence of nematodes against larvae of the south-American fruit fly in laboratory using soil from Porto Amazonas, Paraná, Brazil, as substrate Ciência Rural
Foelkel,Ester; Monteiro,Lino Bittencourt; Voss,Marcio.
ABSTRACT: Anastrepha fraterculus is an important orchard pest. Its management has been based in chemical sprays, but biological control is a growing demand. The objective of this work was to evaluate, under laboratory conditions, the virulence of eight nematode isolates to A. fraterculus in a soil collected in Porto Amazonas, Paraná, Brazil, and to estimate lethal doses (LD50 and LD90) for the more virulent isolate. Steinernema carpocapsae CB 02, three Heterorhabditis sp., two H. amazonensis and two Oscheius sp. isolates were tested in laboratory against A. fraterculus third-instar larvae using as substrate a loam Cambisol collected in an apple orchard. S. carpocapsae CB 02 isolate caused the higher percent mortality of A. fraterculus. Heterorhabditis sp....
