| Abstract |
Laboratory and semifield evaluation of the effeciency of entomopathogenic nematodes (EPN) alone or mixed with wax remover Oleyl-polypeptide, Malathion and Super Misrona oil against adults and nymphs of the mealybug Ferrisia virgata (Cockerell) (Hemiptera: Pseudococcidae) were carried out. In the laboratory, the effeciency of EPN alone increased with increasing infection dose. Also, the effeciency of EPN increased by mixing with Oleyl- polypeptide. The rank of the efficiency of the tested materials in laboratory against the nymphs were Malathion and nematodes mixed with Oleyl-polypeptide, then Super Misrona and finally nematodes only, while, the efficiency of the same tested materials against adults were ordered as follow: nematodes mixed with Oleyl-polypeptide, Malathion, nematodes only then Super Misrona. In semifield, the mortality percentages of nymphs were more than that of adults when adding Oleyl-polypeptide with nematode. Malathion scored the highest mortality against adults and nymphs of F. virgata were 91.74 and 93.64% respectively. In semifield, the rank of the efficiency of the tested materials for nymphs was Malathion followed by the mineral oil, then nematodes mixed with Oleyl-polypeptide and finally nematodes only. The rank of the efficiency for adults was slightly differed from nymphs, where, the efficiency of the nematodes mixed with Oleyl-polypeptide was greater than that of mineral oil. Generally, the reproduction potential seems to be affected by the nematode dose. Nematode recovery from dead F. virgata adults and nymphs were negatively affected by increasing the nematode dose.
