Efficient Sex Pheromone Trapping: Catching The Sweetpotato Weevil, Cylas formicarius [PDF]

Journal of Chemical Ecology, 2012
The sweetpotato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae), is the most serious pest of sweetpotato around the world, damaging sweetpotatoes in the field and in storage, as well as being a quarantine pest. Because the larval period is spent within vines or tubers, and the adults are nocturnal, chemical control frequently is not ...

Investment Trade-Off between Mating Behavior and Tonic Immobility in the Sweetpotato Weevil Cylas formicarius (Coleoptera: Brentidae) [PDF]

Insects, 2023
Numerous studies have confirmed that the trade-off between anti-predator behavior and mating behavior occurs in certain insect species. This suggests that insects invest more in anti-predator behavior, and fewer resources or time can be used in mating ...

Effect of population density of Cylas formicarius (Fabricius) (Coleoptera: Brentidae) on the progeny populations

Applied Entomology and Zoology, 2001
Adults of the sweet potato weevil, Cylas formicarius, were allowed to lay eggs on a 150 g tuberous root of sweet potato for 3 days under conditions of 27°C, 60% RH, and 14L:10D. The number of progeny increased with the increase of parental density, and reached the saturation level. The number of progeny per parental female showed a peak at 30–100 pairs

Decoding attraction: Improving vine weevil monitoring by exploiting key sensory cues

Pest Management Science, Volume 79, Issue 11, Page 4635-4643, November 2023., 2023
Vine weevil adults preferred black, tall and large‐diameter monitoring tools. Monitoring tool density influenced the number of vine weevils recorded in monitoring tools. By contrast plant density did not influence the number of weevils recorded in monitoring tools.

Identification of the key morphological sweetpotato weevil resistance predictors in Ugandan sweetpotato genotypes using correlation and path‐coefficient analysis

Crop Science, Volume 63, Issue 3, Page 1126-1138, May/June 2023., 2023
Abstract Sweetpotato weevils (SPWs) can cause up to 100% yield losses in sweetpotato (Ipomoea batatas). Nevertheless, there has been limited success in breeding for SPW resistance globally. This is attributed partly to difficulty in screening for resistance because resistance to the SPW is complex and is mediated by several resistance indicators ...

Resporulation of Metarhizium anisopliae granules on soil and mortality of Tenebrio molitor: Implications for wireworm management in sweetpotato

Annals of Applied Biology, Volume 182, Issue 1, Page 65-76, January 2023., 2023
Fungal granules inoculated on sterilised soil caused upto 76% mealworm mortality. Abstract In Australia, sweetpotato (Ipomoea batatas L.) is vulnerable to root feeding insect pests such as wireworms (e.g., Agrypnus spp.). The number of registered insecticides to control these insect pests is limited and often pest pressure, for example by wireworms, is

Effects of domestication on quality control parameters of the Queensland fruit fly Bactrocera tryoni (Diptera: Tephritidae)

Journal of Applied Entomology, Volume 146, Issue 6, Page 687-699, July 2022., 2022
Abstract The Queensland fruit fly (Q‐fly), Bactrocera tryoni (Froggatt), is a major horticultural pest in Australia. Sterile insect technique (SIT) is increasingly used in area‐wide integrated management of Q‐fly, as well as for eradication of outbreaks in Q‐fly‐free regions.
