| Abstract | ||
| A study was conducted to offer a preliminary understanding of the role played by intensively used field controlling agents, two mineral oils, namely Alboleum and Super Misrona oils as well as an IGR, Admiral (pyriproxyfen) with the recommended doses upon adult female mealybug Ferrisia virgata (Pseudococcidae: Homoptera) as an arbitrary model for mealybugs. The present work points out to the importance of the delayed effect of these different compounds. The highest increase in the total protein content was achieved by Admiral reached 29.2% while Super Misrona caused the greatest enhancement in the total carbohydrates concentration (72.93%). On the other hand, Alboleum caused a highly significant inhibition in the activity of glutamic oxaloacetic transaminases (GOT) and glutamic pyruvic transaminases (GPT) reached 82.03 and 22.10 %, respectively. These biochemical changes were intensively discussed. Among most of the tested biochemical parameters, Admiral showed the strongest delayed effect. | ||
