The tomato leafminer, Tuta absoluta is a serious pest of tomato crops worldwide. In this study the effect of sublethal concentrations of abamectin (at 10 and 30% lethal concentrations, LC10 and LC30) was investigated on developmental and reproduction parameters of the tomato leafminer Tuta absoluta. Lethal concentrations were estimated by leaf dip bioassay on the fourth instar larvae of the T. absoluta that, LC50, LC30 and LC10 were 0.23, 0.15 and 0.12 mg · l–1, respectively. The sublethal concentrations led to significant decreases in adult emergence, the percentage of pupation of the parent generation, fecundity and adult longevity compared to the control. Sublethal concentrations significantly decreased the net reproductive rate (R0), intrinsic rate of increase (r), finite rate of increase (λ), and gross reproduction rate (GRR). There was a significant decrease in the time to egg developmental and doubling time (DT) of T. absoluta. However, sublethal concentrations of abamectin had no significant effects on the percentage of pupation, larva, prepupa and pupa developmental periods, hatchability and sex ratio of offspring. The results of this study indicated that sublethal concentrations of abamectin could influence some biological parameters of T. absoluta. The results could also be helpful for making better management decisions for controlling the tomato leafminer.

The mini-plots experiment was made on the effectiveness of selected chemicals to reduce damage to Chinese cabbage caused by Arion lusitanicus slugs. Two active substances used as spray, seed coating and molluscicides were tested. Effective action in reducing plant damage by slugs showed methiocarb and abamectin used as spray. The damage was reduced also by abamectin used as a seed coating. It was found that the effectiveness of methiocarb and abamectin, applied in the form of spray, was comparable to the efficiency of molluscicide Mesurol Alimax 02 RB (2% methiocarb).

Efforts have been made during the past three decades to develop insecticides with selective properties that act specifically on biochemical sites present in a particular insect group, but whose properties differ from those present in mammals. This approach has led to the discovery of compounds that affect the hormonal regulation of molting and developmental processes in insects such as ecdysone agonists, juvenile hormone (JH) mimics and chitin synthesis inhibitors. The search for potent acylureas has led to the development of novaluron (Rimon) developed by Makhteshim Chemical Works. The LC-50 value of novaluron on 3rd-instar Spodoptera littoralis fed on treated leaves is approximately 0.1 mg a.i./liter. This value resembles that of chlorfluazuron and is tenfold lower than that of teflubenzuron. Novaluron affects nymphs of Bemisia tabaci more than chlorfluazuron and teflubenzuron. Artificial rain, at a rate of 40 mm/h applied 5 and 24 h after treatment in a cotton field had no appreciable effect on the potency of novaluron on both S. littoralis larvae and B. tabaci nymphs. Hence, novaluron can be used in tropical areas and during rainy seasons. In general, benzoylphenyl ureas had no direct effect on parasitoids and phytoseiids and are considered mildly affect other natural enemies. Novaluron has no cross-resistance with conventional insecticides, the JH mimics pyriproxyfen and neonicotinoids. As such, it is considered an important compound in pest management programs.
