Insecticides are unavoidable in pest management programs especially when the pest crosses Econimic Threshold Level (ETL). Nevertheless, often the plant protection products kill the natural enemy population making the pest to resurge and thus demanding more sprays. Therefore, insecticides used in IPM programs should be selective enough to spare the beneficials. Laboratory studies were conducted to find out the toxicity of imidacloprid and diafenthiuron to the eggs, larvae and adults of Chrysoperla carnea. Imidacloprid at the recommended dose of 0.28 ml/l caused 15.38% egg mortality, 26.67 and 33.33% larval mortality by ingestion and contact, respectively and 50.00% adult mortality. The egg mortality was about 15.38% and larval mortality of 23.33% and adult mortality of 26.67% was caused by diafenthiuron. Based on the classification given by IOBC/WPRS working group on Pesticides and non-target invertebrates, both the insecticides were classified as harmless to C. carnea, since the recommended dose caused less than 50% mortality in the laboratory conditions.

The black citrus aphid, Toxoptera aurantii Boyer de Fonscolombe (Hemiptera: Aphididae), an important pest of citrus species, feeds by sucking sap from plant leaves. It causes some leaf distortion and malformation of growing leaves and shoot tips. In this study, the eff ects of the botanical insecticide, palizin on T. aurantii and its parasitoid, Aphidius colemani Viereck (Hymenoptera: Brachonidae) were compared with the chemical insecticide, imidacloprid. Th e compounds were evaluated at maximum recommended fi eld concentrations: palizin 2,000 ppm, imidacloprid 500 ppm, water (as control) on adult aphids. Spraying was done with a 100-l engine Honda sprayer (GX120T1, 160T1, 200T) until run-off . Th e number of dead aphids was recorded 24, 48 and 72 hours aft er treatment. According to the results, statistically signifi cant diff erences were found between treatments (p ≤ 0.05). Twenty-four hours aft er treatment, imidacloprid was more eff ective than palizin in reducing the T. aurantii population. Palizin showed high effi ciency (95% mortality) 72 hours aft er treatment. However, at that time, there was no statistically signifi cant diff erence between the mean mortality percentages of imidacloprid and palizin. This shows that botanical insecticide, palizin can eff ectively control T. aurantii. Also, palizin caused low mortality (10.86%) on A. colemani while imidacloprid was more toxic (31.1% mortality). The results of the present study indicated that palizin can be used instead of chemical insecticide, imidacloprid in control programs of T. aurantii.

Laboratory studies were carried out to compare the toxicity of the chloronicotinyl insecticide, imidacloprid on parasitoids. The studies took place at the Tamil Nadu Agricultural University, Coimbatore from 2006–2007. Imidacloprid was tested against three beneficial insects viz., an egg parasitoid, egg larval parasitoid and a larval parasitoid representing two families of Hymenoptera: Trichogrammatidae (Trichogramma chilonis Ishii) and Braconidae (Chelonus blackburni Cameron; Bracon hebetor Say) that attack insect pests of cotton. The toxicity of imidacloprid was evaluated by treating the parasitized eggs using an atomizer in the case of T. chilonis and glass scintillation vial residue bioassay method for the adults of C. blackburni and B. hebetor. The toxicity of imidacloprid to parasitoids was compared with another neonicotinoid, named thiamethoxam, and a standard check, methyl demeton. Imidacloprid 17.8 SL did not cause any adverse effects on the adult emergence and parasitization of T. chilonis. At the recommended dose of imidacloprid [25 g active substance (a.s.)/ha], 90.67 and 85.32 per cent adult emergence and parasitization was recorded, respectively. The recommended dose of imidacloprid caused 56 per cent mortality and was found to have moderate impact on the adults of C. blackburni. On the other hand, it was found to be toxic to the parasitoid B. hebetor, causing 70 per cent mortality at 48 hours after treatment (HAT). The data presented here will provide pest managers with specific information on the compatibility of selected insecticides with natural enemies attacking pests of cotton, Gossypium hirsutum L.

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.
