“…This suggested that the extract acted as a stomach poison (Salam and Ahmed, 1997). In no-choice tests, adults of Xanthogaleruca luteola fed on leaves treated with 2.5 or 10% M. azedarach extract showed a dramatic increase in mortality rates (Defago et al, 2006). The highest toxicity rates were recorded for oil of M. azedarach, 100% and 77.5% mortality with 2 nd and 4 th instars, respectively, at the highest concentration of 20 g/100 mL, while the crude extract caused 85% and 65% mortality with the two instars at the same concentration.…”

“…Ahmed et al (1978) stated that the acetone extract of M. azedarach afforded a signifi cant degree of determent with some instars of S. littoralis. Defago et al (2006) reported that treatment of elm leaves with extracts obtained from unripe fruits and green or senescent leaves of M. azedarach at 1 -10% content signifi cantly deterred feeding of the adult elm leafbeetle, Xanthogaleruca luteola. Jianzhang et al (1983) found that the seed oil of M. azedarach had various adverse effects on several important rice pests.…”

A crude acetone extract and oil of ripe fruits from Melia azedarach L. were evaluated against the 2 nd and 4 th instar larvae of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). Both oil and extract exhibited highly signifi cant growth inhibition at all concentrations tested, while the oil of M. azedarach recorded higher insecticidal activity against both instars than the crude extract. GC-MS analysis of the oil revealed the presence of linoleic acid methyl ester, oleic acid methyl ester, and free oleic acid as the main components in addition to hexadecanol, palmitic acid, methyl esters of stearic acid and myristic acid. Fatty acids and their esters were not only the main constituents of essential oil from the ripe fruits of M. azedarach, but also mainly responsible for the insecticidal and growth inhibition activity against S. littoralis.

“…The antifeedant experiments were carried out by the leaf-disk choice test for compounds 1 and 2 [30]. Two circular sections of the leaves of Lactuca sativa or C. maxima for S. frugiperda and E. paenulata, respectively, were placed in a Petri dish and a glass disk with two 1 cm 2 holes was placed on top.…”

Insecticidal Properties of a Highly Potent Wax Isolated from Dolichandra cynanchoides Cham

Bioassay-guided fractionation of an ethanolic extract of the aerial parts of Dolichandra cynanchoides Cham. (Bignoniaceae) led to the isolation of a natural wax with anti-insect activity against Spodoptera frugiperda (Noctuidae) and Epilachna paenulata (Coleptera). The compound was identified spectroscopically as an ester of a C27 fatty acid and a C25 alcohol, pentacosyl heptacosanoate (1). The effective doses of 1 for 50% feeding inhibition (ED 50 ) of S. frugiperda and E. paenulata were 0.82 and 8.53 µg/cm 2 , respectively, in a choice test, while azadirachtin showed ED 50 of 0.10 and 0.59 µg/cm 2 , respectively. In a no-choice test, both insects refused to feed on leaves treated with 1 at doses of 0.1 µg/cm 2 or greater inhibiting larval growth and dramatically reducing survival. The lethal doses 50 (LD 50 ) of 1 were 0.39 and 0.68 µg/cm 2 for S. frugiperda and E. paenulata, respectively. These results indicate that 1 has potential for development as botanical insecticides. Similar esters might be obtainable in large quantities as many edible crops produce wax esters that are discarded during food processing. Research on these materials could lead to the detection of similar waxes with insecticidal activity.

“…Due to the widespread plantation of elm trees in urban areas, the application of pesticides against X. luteola poses some special risks. Therefore, the application of pesticides with high selectivity to the pest and low toxicity to humans and environment is highly appreciated (Defago et al 2006).…”

Mohammadzadeh Tamam B., Ghadamyari M., Sahragard A., Karimi-Malati A. (2014): Sublethal effects of spinosad on some biochemical parameters of Xanthogaleruca luteola (Müller) (Coleoptera: Chrysomelidae). Plant Protect. Sci., 50: 199-205.The effect of spinosad on some biochemical characteristics of Xanthogaleruca luteola was investigated. LC 30 and LC 50 of spinosad for the third instar larvae were determined as 1.6 and 2.9 ppm, respectively. Biochemical tests were carried out on the 3 rd instar larvae treated with LC 30 and LC 50 of spinosad. The LC 30 concentration decreased carbohydrate and glycogen content and increased lipid content significantly. There was a significant decrease in carbohydrate, glycogen, and protein contents following the exposure to LC 50 concentration. Available energy of the larvae exposed to LC 30 of spinosad increased significantly, whereas it decreased significantly at LC 50 . However, the energy consumed was increased at both concentrations significantly. Cellular energy allocation of larvae treated with LC 50 concentrations of spinosad decreased significantly. Glutathione-S-transferase and esterase activities were increased significantly at LC 50 . However, lipase activity was decreased at both concentrations.
