Abstract Uridine diphosphate glucosyltransferases (UGTs), which are phase II detoxification enzymes, are found in various organisms. These enzymes play an important role in the detoxification mechanisms of plant allelopathy and in insects. Artemisia vulgaris L. (Asterales: Asteraceae: Artemisia) essential oil has strong contact toxicity to Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) larvae. However, the effect of A. vulgaris essential oil on UGTs is unclear. In this study, A. vulgaris essential oil was shown to significantly induce the expression of the TcUgt86Dg transcript. Furthermore, treatment of TcUgt86Dg-silenced individuals with A. vulgaris essential oil resulted in higher mortality than for the control individuals, indicating that TcUgt86Dg is involved in detoxification of A. vulgaris essential oil in T. castaneum. The developmental expression profile showed that the expression of TcUgt86Dg in late adults was higher than in other developmental stages. Furthermore, the expression profile in adult tissues revealed higher expression of TcUgt86Dg in the head, antenna, fat body, and accessory gland than in other tissues. These data show that TcUgt86Dg may be involved in the metabolism of exogenous toxins by T. castaneum; thus, our results have elucidated one possible mechanism of resistance to A. vulgaris essential oil and provide a theoretical basis for a control scheme for T. castaneum.

Essential oils extracted from leaves and fruits of Schinus areira (Anacardiaceae) were tested for their repellent, toxic and feeding deterrent properties against Tribolium castaneum (Coleoptera: Tenebrionidae) larvae and adults. A topical application assay was employed for the contact toxicity study and filter paper impregnation for the fumigant assay. A treated diet was also used to evaluate the repellent activity and a flour disk bioassay for the feeding deterrent action and nutritional index alteration. The essential oil of the leaves contained mainly monoterpenoids, with α-phellandrene, 3-carene and camphene predominant, whereas that from the fruits contained mainly α-phellandrene, 3-carene and β-myrcene. The leaf essential oil showed repellent effects, whereas that from the fruit was an attractant. Both oils produced mortality against larvae in topical and fumigant bioassays, but fumigant toxicity was not found against adults. Moreover, both essential oils produced some alterations in nutritional index. These results show that the essential oils from S. areira could be applicable to the management of populations of Tribolium castaneum.

Essential oils (EOs) are mixtures of volatile organic compounds, mostly terpenes, from the secondary metabolism of plants. These oils exert various activities on insects that damage crops and cause losses worldwide for the economy and agriculture. Tribolium castaneum Herbst (Coleoptera: Tenebrionidae) is one of the main pests causing the loss of a large amount of stored food. The objective of this study was to evaluate the volatile chemical composition of the essential oil from Piper gorgonillense Trel. & Yunck. and its repellent and fumigant activity on T. castaneum. The volatile composition was determined with gas chromatography coupled to mass spectrometry. The majority compounds found in the EO were b-caryophyllene (28.7%), a-copaene (13.5%), and d-cadinene (7.3%). The repellency percentages obtained were 78 and 90% at a concentration of 1% with exposure times of 48 and 72 hours, respectively. The fumigant activity refers to the insecticidal action that an essential oil vapor can have without coming into direct contact with insects; this was 100% at a concentration of EO 350 µg mL-1. The results showed that the P. gorgonillense EO had repellent and insecticidal properties for the biological control of T. castaneum.

Tribolium castaneum es una plaga que infesta los productos agrícolas almacenados, principalmente granos. Una alternativa de control son los productos naturales, destacándose los aceites esenciales. Se evaluó la actividad repelente del aceite esencial de Bursera graveolens Jacq. ex L. contra T. castaneum aplicando el método de área de preferencia. Los resultados muestran diferencias significativas (p menor que 0.005) entre el área tratada y no tratada en las dosis 0.02, y 0.2 µL/cm2 luego de dos horas de exposición. Dicha actividad decreció al aumentar el tiempo de exposición. En conclusión, el aceite esencial de B. graveolens podría ser un repelente efectivo contra este insecto plaga. Tribolium castaneum (Herbst, 1797) is a plague that infest store products, mainly grains. One alternative to control it is the use of natural products, highlighting the essential oils. It was evaluated the repellent activity of the essential oil of Bursera graveolens Jacq. ex L. towards T. castaneum. Results shows significant differences (p less than 0.005) between the treated area and the non trated area at 0.02, and 0.2 µL/cm2 doses after two hours of exposition. Repellent activity decreased when the time of exposition increased. In conclusión, the essential oil of B. graveolens could be an effective repellent against plague insects, being also this report the first related to repellency in this plant.
