Insecticide Activity of Essential Oils on the Development of Eggs and Adult of Caryedon serratus Olivier (Coleoptera: Chrysomelidae), Pest of Stored Groundnut

This study evaluated the insecticidal activity of Gallesia integrifoliaessential oil from fruits, leaves, and flowers against Aedes aegyptilarvae and pupae. The essential oil was obtained by hydrodistillation and characterized by gas chromatography-mass spectrometry. Sulfur compounds represented 95 to 99% of the essential oil from fruits, leaves, and flowers. Essential oil major compounds were 2,8-dithianonane (52.6%) in fruits, 3,5-dithiahexanol-5,5-dioxide (38.9%) in leaves, and methionine ethyl ester (45.3%) in flowers. The essential oils showed high activity against larvae, and low for pupae withLC99.9of 5.87 and 1476.67μg/mL from fruits; 0.0096 and 348.33 μg/mL from leaves and 0.021and 342.84 μg/mL from flowers, respectively. The main compound with insecticide activity is probably n-ethyl-1,3-dithioisoindole, from isoindole organothiophosphate class, found in greater amount in flower and leaf essential oil. The great insecticide activity of G. integrifoliaessential oil suggests that this product is a natural insecticide.

Pupal Mortality

ABSTRACT Liriomyza sativae (Blanchard) is a worldwide polyphagous pest for horticultural and ornamental crops, whose chemical control is the major method adopted. However, botanical insecticides in the form of essential oils (EOs) are presented as promising alternatives. This study aimed to evaluate the effect of EOs from the species Croton sonderianus Muell. Arg., Croton conduplicatus Kunth., Lippia gracilis Schauer and Lippia schaueriana Mart. on the biological aspects of L. sativae adults and immature stages (larva and pupa). The results showed larval and pupal mortality after the immersion of leaves with newly hatched L. sativae larvae in EOs solution from L. gracilis and L. schaueriana leaves. The EOs from C. conduplicatus stem bark and leaf and from C. sonderianus stem bark extended the leafminer pupal stage duration, while those from C. conduplicatus leaves and C. sonderianus stem bark decreased the oviposition and feeding punctures in no-choice tests. Only C. conduplicatus confirmed the effect in the free-choice test, showing to be the most promising in the study. This way, EOs from L. gracilis and L. schaueriana leaves show an insecticide activity on L. sativae larvae, and those from C. conduplicatus leaves reduce the leafminer oviposition and feeding punctures in melon plants.
