“…Sex pheromone compounds released by females consist of 2 or more compounds. The eleven compounds associated with sex attractant activity were isolated from female Spodoptera exigua [11], The feasibility of synthetic sex pheromone for the control of the beet armyworm, Spodoptera exigua, in the field was a 7:3 mixture of (Z, E)-9, 12-tetradecadienyl acetate and (Z)-9-tetradecen-1-ol [12]. Sex pheromone for S. exigua Indonesian population consist of (Z, E)-9, 12-tetradecadienyl acetate and (Z)-9-tetradecen-1-ol with ratio 90:10 [13].…”

Spodoptera exigua is considered as one of the most important pests in shallot plant. The objective of the research was to evaluate activity of synthetic pheromone which diluted in glue (glue formulation) for monitoring the Spodoptera exigua moth populations. This research was conducted from November until December 2021 in Tanah Datar, Bukittinggi Regency, West Sumatera. A sex pheromone glue formula was spread on yellow board trap and applied on shallot at 14 days after planting. This research was done using a randomized design, consist of sex pheromone glue formula treatments, with different amount of active components of adhesive glue (in 100 mL) i.e. A (50 µg), B (100 µg), C (200 µg), D (300 µg), and one trap without sex pheromone as control (E). Each treatment was repeated five times. The observation was made by counting the number of moths caught in the sex pheromone trap. The results showed that an effective sex pheromone formula to attract male moths was the B formula. The B (100 µg) formula can catch more male moths higher than that of other formulas and recommended further to utilize for monitoring of S. exigua.

“…The effective use of mating disruption with sex pheromones to control many other pest species of Lepidoptera has now been established, including the Oriental fruit moth [186], codling moth [187], grape root borer [188] [197], beet armyworm [198,199] been developed for the light-brown apple moth [200], a complementary approach to the use of pheromones in monitoring insecticide resistance in field populations as discussed above. Many different types of dispensers are now commercially available for use as multiple release sources.…”

Chemical communication is important in the life cycles of many insect species, principally for the location of mates and food. Structural identification and synthesis has been carried out for many semiochemicals, and a number of techniques have been developed to use these compounds as components of integrated pest management (IPM) programs. Semiochemicals have two main uses in IPM programs: monitoring insect pest populations and preventing agricultural damage by interfering with insect behavior. Pheromones are perhaps the most widely exploited semiochemicals at present, but recent efforts have extended increasingly to the identification and use of compounds involved in interspecific exchange of information as well.The use of semiochemicals to manipulate insect behavior has proved to be one of the most useful components of integrated pest management (IPM) programs. Semiochemicals are compounds that are emitted or displayed by one organism and that affect the behavior of another organism [/]. Perhaps the most important semiochemicals used by insects are those involved in locating mates and food, and at present these are the kinds of semiochemicals most widely exploited for insect control. Semiochemicals with many other kinds of ecological roles have also been characterized in insects, such as compounds that function as warnings, or compounds that mediate the collective activity of many partners in completing large tasks. A number of major reviews of the use of semiochemicals in IPM programs have appeared [7][8][9], as well as a critical review of semiochemical utility in general [10], An extensive list of companies that offer semiochemical lures, traps designed for semiochemical monitoring, and commercial systems for behavioral pest control has been compiled by Inscoe [11].Practical applications of semiochemicals in agriculture fall into two main categories, population monitoring and behavioral pest control. The main use at present is in monitoring insect pests with traps baited with semiochemicals, as a part of making decisions about pesticide application or other control techniques. A second use of semiochemicals is the direct prevention of insect damage by a variety of techniques, including the placement of a large number of semiochemical sources that disrupt the behavior of the insects, mass trapping, attracticides (insecticide lures), and enhancement of parasitoid activity.

“…This phenomenon has made it difficult to control this insect pest using insecticides alone, and other approaches such as mating disruption using a synthetic sex pheromone, and the use of a nucleopolyhedrovirus (SeNPV)-based insecticide have had to be considered. [20][21][22][23][24][25][26] Many studies showed that when conditions were right, mating disruption using a synthetic sex pheromone significantly reduced the population of beet armyworm in the field. 27) However, the use of SeNPV has no immediate effect on the control of the beet armyworm.…”

Permethrin Resistance Mechanisms in the Beet Armyworm (Spodoptera exigua (Huebner))

et al. 2005

The toxicity of pyrethroids was evaluated in a permethrin-susceptible (TS) and a permethrin-resistant (TR) strain of the beet armyworm, Spodoptera exigua (Hübner). The TR-strain showed 92-fold more resistance to permethrin and higher cross-resistance (97-and 130-fold, respectively) to cypermethrin and fenvalerate than the TS-strain. Moreover, all larval instars exhibited greater susceptibility to permethrin in the TS-strain than TR-strain. There was very little difference in susceptibility between the two strains with respect to chlorphenapyr. The effect of piperonyl butoxide on the toxicity of permethrin indicated that the resistance of the TR-strain is due to enhanced metabolic detoxification by cytochrome P450 monooxygenase.
