DDT and its fluoro- and methyl-analogues, its carbinol and carbinol acetate, and monochlor-DDT (1-(4-chIorophenyl)-1-phenyl-2,2,2-trichloroethane) were tested for contact insecticidal activity against two beetles (Calandra granaria and Tribolium confusum), a moth (Ephestia kuhniella), a plant bug (Oncopeltus fasciatus), and a cockroach (Blatella germanica).Fluoro-DDT showed specificity against the cockroach and carbinol-DDT against the plant bug. Comparisons with the results of earlier testing against Drosophila melanogaster justified its use as an indicator species.

AbstractFlying insects have invaded all the aerial space on Earth and this astonishing radiation could not have been possible without a remarkable morphological diversification of their flight appendages. Here, we show that characteristic spatial expression profiles and levels of the Hox genes Antennapedia (Antp) and Ultrabithorax (Ubx) underlie the formation of two different flight organs in the fruit fly Drosophila melanogaster. We further demonstrate that flight appendage morphology is dependent on specific Hox doses. Interestingly, we find that wing morphology from evolutionary distant four-winged insect species is also associated with a differential expression of Antp and Ubx. We propose that variation in the spatial expression profile and dosage of Hox proteins is a major determinant of flight appendage diversification in Drosophila and possibly in other insect species during evolution.

Bisnoriridodial and cis-bisnoriridolactone have been synthesized. The 1,5-dialdehyde-δ-lactone rearrangement of the former compound is compared with that of iridodial. The insecticidal activity of the naturally occurring iridolactones, and of related synthetic compounds, is reported.

Dysdercus Peruvianus

Studies were carried out to evaluate the insecticidal activity of Pilocarpus spicatus Saint-Hilaire (Rutaceae) essential oil (EO) on the development of the Hemiptera Dysdercus peruvianus (Guérin-Méneville, 1831) and Oncopeltus fasciatus (Dallas, 1852). Gas Chromatography/Mass spectrometry analysis revealed a chemical composition with sabinene (32.27%) and sylvestrene (27.26%) as major constituents. Topical and continuous treatment with the pure EO induced 100% of mortality while serial dilutions of the EO induced different levels of lethality in a dose response manner. Median lethal dose (LD50) and lethal dose 90% (LD90) were determined. Malformations in insects and permanent or supernumerary nymphs were often observed after treatments, and the use of scanning electron microscopy allowed the analysis of morphological changes. The different biological effects of P. spicatus EO point out its potential as a rich source of bioactive molecules to be used as an alternative control method against agricultural pest insects.
