چکیده
The seasonal occurrence of the beet armyworm, Spodoptera exigua (Hübner), and the southern armyworm, Spodoptera eridania (Cramer), was monitored over a 2year period using International Pheromones, Ltd. Moth Traps baited with rubber septa impregnated with pheromone blends identified from conspecific females and also with pheromone emitted by live female beet armyworm moths. The pheromone blend for beet armyworm was (Z)-9-tetradecen-1-ol (2.5%), (Z,E)-9,12-tetradecadien-

Dynamic properties of antennal responses to pheromone in two moth species.
Dynamic properties of pheromone plumes are behaviorally important in some moths for inducing upwind flight, but little is known about the time-dependent properties of odor transduction or the mechanisms that limit receptor dynamic sensitivity. We stimulated male antennae of two moth species, Cadra cautella and Spodoptera exigua, with pheromone plumes in a wind tunnel while recording electroante...
متن کاملSynthetic pheromones and plant volatiles alter the expression of chemosensory genes in Spodoptera exigua
Pheromone and plant odorants are important for insect mating, foraging food sources and oviposition. To understand the molecular mechanisms regulating pheromone and odorant signaling, we employed qRT-PCR to study the circadian rhythms of ABP, OBP, PBP, and OR gene expression in the beet armyworm, Spodoptera exigua and their responses after a pre-exposure to sex pheromone compounds or plant vola...
متن کاملAntennal resolution of pulsed pheromone plumes in three moth species.
Male antennae of Cadra cautella, Pectinophora gossypiella, and Spodoptera exigua were presented with 20-ms-duration pulses of their two-component pheromone at rates of 1 to 33 Hz. Fourier analyses of electroantennograms resolved the temporal structure of trains of pheromone filaments delivered at up to 33 Hz for C. cautella and S. exigua and 25 Hz for P. gossypiella. Pheromone components tested...
متن کاملBrassica IPM adoption: progress and constraints in south-east Asia
The Integrated Pest Management (IPM) programme for brassicas in many countries of south-east Asia follows a generic model whose basic components are: (i) Regular scouting of pests, namely the diamondback moth (DBM) and its major natural enemies to ascertain their population levels to justify insecticidal treatments; (ii) Use of pre-determined economic threshold levels (ETLs) and (iii) Incorpora...
متن کاملGains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
