| Abstract | Efficacy of essential oil from Lantana camara L. as the fumigant, contact toxicity and progeny deterrent were tested against lesser grain borer, Rhyzopertha dominica (Fabricius). Concentrations of essential oil from L. camara at 0, 20, 40, 60, 80 and 100 ??l/mlwere applied with 5 replications. The experiment was conducted at biology laboratory under25-27?oC and 75-80% RH conditions. Results showed that the fumigant, contact toxicity andprogeny deterrent of essential oil from L. camara on the lesser grain borer wereeffective when compared with control. At concentration of 100? ?l/ml, using it as fumigantgave 70% mortality with the LC50 value of 76.45? ?l/ml at 24 h, while the contact toxicitygave 94% mortality with the LC50 value of 50.00? ?l/ml at 24 h. For progeny deterrenteffects, using the same concentration of essential oil and starting from5 pairs of parent, the number of derived progeny was 1.80 ? 0.74 adults, percentage ofprogeny deterrent was 94.11 and the time of development was 54.40 ? 1.62 days. Whereasin control, the number of progeny was 30.60 ? 2.55 adults, percentage of progeny deterrentwas 0.0% and the time of development was 28.60 ? 3.35 days. |
