Pheromone-based mating disruption is used worldwide for management of the internal fruit feeding codling moth, Cydia pomonella (L.). There has been recent interest in the potential of improving mating disruption of C. pomonella, and potentially other insect species in general, by broadcasting combinations of pheromone and attractive host-plant kairomones. Given that such kairomones are attract...

Cacao is a promising high-value crop in the Philippines and considered one of key players globally providing raw materials for chocolate making. However, before can take this market opportunity, production constraints from various pests should be addressed. The cacao pod borer (CPB), Conopomorpha cramerella , major insect Philippines, which cause up to 50% annual loss or even higher if proper m...

W. Barros-Parada, A.L. Knight, E. Basoalto, and E. Fuentes-Contreras. 2013. An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards. Cien. Inv. Agr. 40(2):307-315. Studies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricid...

Thrips, mite and borer complex are the most serious insect pests which reduce chilli yield remarkably in many growing areas. This study exposed that sustainable bio-rational based management packages including different mechanical approaches bio-pesticides were effective against chilli. The results indicated that, spraying of Sodium lauryl ether sulphate (Fizimite) Matrine (Biotrin) along with ...

The Indianmeal moth, Plodia interpunctella (Hübner), was selected as a representative stored-product moth to test the validity of contour mapping of trap catch for pest monitoring in warehouses and retail stores. Three experiments, each replicated five times, were conducted in a 3.2 by 9.0-m aluminum shed. Each experiment involved placing pupae at a single release point (source) and recording t...

Traps baitedwith the synthetic aggregation pheromoneof the bollweevil (Anthonomus grandis Boheman) are often used to monitor population ßuctuations, distribution, and behavior. However, many factors generate variability in daily captures, making interpretation of trapping data difÞcult. Previous studies have shown that wind speed in the microenvironment around a trap can greatly affect numbers ...

1. The pink bollworm moth Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is one of the most destructive pests in agriculture. An ongoing eradication program using a combination of sex pheromone monitoring and mating disruption, irradiated sterile moth releases, genetically modified Bt cotton and local insecticide applications have all but exterminated the pink bollworm from the ...

Contract administrator: Mary Lou Bricker ([email protected]) (509) 335-7667; or Tom Kelly ([email protected]); (509) 335-3691 Objectives: 1. Modify and validate fall pheromone trap sampling as a method of identifying high-risk orchards for spring sampling (‘Delicious’ and ‘Golden Delicious’). 2. Determine the relative susceptibility to C. verbasci damage of apple cultivars other than ‘Delicious’ an...

Field studies were conducted from 1992 to 1996 to select the most effective sex pheromone blend for mating disruption of the obliquebanded leafroller, Choristoneura rosaceana (Harris), in tree fruit orchards in Washington. Dispensers loaded with a 2-component pheromone blend, (Z)-1l-tetradecen-1-yl (Zll-14:0Ac) and (E)-1l-tetradecen-1-yl (Ell-14:0Ac), a 3-component blend that included the addit...
