The influence of trap placement on catches of codling moth, Cydia pomonella L., was examined in a series of studies conducted in orchards treated with Isomate-C Plus sex pheromone dispensers. Mark-recapture tests with sterilized moths released along the interface of pairs of treated and untreated apple and pear plots found that significantly more male but not female moths were recaptured on int...

Abstract Field experiments were carried out in the reclaimed land east of Cairo-Alexandria Desert Road, Village Wardan, Giza Governorate, Egypt, to evaluate impact using nano-gels pheromone for first time on attraction RPW adults by traps compared control which is normal during two successive seasons 2018 and 2019. Also, this study aimed compare efficacy types trap, traditional trap (type 1) dr...

the mating disruption technique has been widely used for the control of several lepidopteran pests. in the present study, we assessed the efficiency of two formulations of splat neo, a wax emulsion containing e-11-hexadecenol, with and without the insecticide cypermethrin, in affecting mating disruption of neoleucinodes elegantalis (guenée). we also determined the best phenological age or stage...

The previously identified female sex pheromone of cocoa pod borer, Conopomorpha cramerella, was re-evaluated for its attractive activity in different field conditions. It was found that lures containing 100-mug of synthetic sex pheromone blend, (E,Z,Z)- and (E,E,Z)-4,6,10-hexadecatrienyl acetates, and the corresponding alcohols in a ratio of 40:60:4:6 in a polyethylene vial attracted male C. cr...

We evaluated attraction of cerambycid beetle species to blends of known cerambycid pheromones to determine whether such blends could be used as effective trap lures for detecting and monitoring multiple species simultaneously. Pheromone-baited traps captured 1,358 cerambycid beetles of which 1,101 (81.1%) belonged to three species in the subfamily Cerambycinae: Neoclytus acuminatus (F.), Neocly...

Banana weevil (Cosmopolites sordidus) is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. A study was conducted in Uganda to determine the effect of mulching on banana (Musa spp. L.) weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), movement relative to pheromone-baited traps. Three treatments were used to create different mulchi...

Abstract The wheat wireworm, Agriotes mancus (Coleoptera: Elateridae), is a predominant elaterid pest species in the Nearctic region, with life history and morphology similar to those of obscurus , lineatus sputator three Palearctic elaterids invasive North America. Here, we report identification field testing sex pheromone A. mancus. We collected headspace volatiles from female beetles on Pora...

Both sex pheromones and male lures appear to play an important role in the mating systems of many species of economically important tephritid species. Typically, stationary males emit pheromone attractive to searching females, and recent evidence indicates that naturally occurring male lures may function as precursors in pheromone synthesis. Here, we review (i) the basic biology of sex pheromon...
