Abstract Male Metamasius spinolae (Gylh.) produce several volatile compounds that are likely constituents of its aggregation pheromone. These compounds were identified by volatile collections and gas chromatography (GC), followed by coupled gas chromatography-mass spectrometry (GC-MS), as 2-methyl-4-heptanone [1], 6-methyl-2hepten-4-one [2], and 2-hydroxy-2-methyl-4-heptanone [3]. Preliminary field experiments using synthetic racemates of these compounds showed that significantly more adult… 
The Aggregation Pheromone of Metamasius spinolae (Coleoptera: Dryophthoridae) Revisited: Less is More
TLDR
Results indicate that 2-hydroxy-2-methyl-4-heptanone is the main component of the aggregation pheromone of M. spinolae, and it is suggested that this compound should be used for developing a monitoring or a mass-trapping system for M.spinolae.
Trapping Scyphophorus acupunctatus (Coleoptera: Curculionidae) with Fermented Tequila Agave, and Identification of the Attractant Volatiles
TLDR
The results obtained indicated that the fermented material was a viable alternative to optimize trapping of S. acupunctatus, because the liberated volatile chemical compounds of the attractant captured a greater number of weevils in the field.
Aggregation Pheromones of Weevils (Coleoptera: Curculionidae): Advances in the Identification and Potential Uses in Semiochemical-Based Pest Management Strategies.
TLDR
The synergistic effect of the host plant volatiles in the attractiveness of weevil pheromones is reported, demonstrating the important role of these additional attractants in the chemical communication of curculionids.
Aggregation pheromone of the agave weevil, Scyphophorus acupunctatus
TLDR
The potential use of the aggregation pheromone in the development of a mass‐trapping programme as a viable pest management alternative for S. acupunctatus is discussed.
Factors in the Response of Agave Weevil, Scyphophorus acupunctatus (Coleoptera: Curculionidae), to the Major Compound in its Aggregation Pheromone
TLDR
It was showed that electrophysiological and behavioral response to 2-methyl-4-octanone differed among populations of agave weevils from different crops and geographical regions, and it was determined that the age of the insect was involved in both responses.
Rate of Release of Rhynchophorol Pheromone in Relation to Attraction of Rhynchophorus palmarum (L.) (Coleoptera: Dryophthoridae) in Oil Palm Plantations in Colombia
TLDR
It is concluded that the release rate of the pheromone of 2.4 mg/day is optimal for the capture of adults of R. palmarum during a period of 4 mo.
Attraction to Host Plant Volatiles and Feeding Performance of Naupactus Xanthographus (Coleoptera: Curculionidae) is Affected by Starvation
TLDR
It is concluded that grape is preferred over avocado for N. xanthographus, the first report on the effect of starvation on the attraction to host plant volatiles in Curculionidae.
Amount and Bagging of the Bait Food Affect the Captures of Scyphophorus acupunctatus (Coleoptera: Curculionidae) by Pheromone-Baited Traps
TLDR
The use of synthetic aggregation pheromone-baited traps may be a useful tool for monitoring or control of the weevil Scyphophorus acupunctatus Gyllenhal, the most important insect pest of wild and cultivated agaves worldwide.

Field trapping of Metamasius hemipterus with synthetic aggregation pheromone
TLDR
The five synthetic pheromone components of the West Indian sugarcane borer, Metamasius hemipterus (L.) (Coleoptera, Curculionidae) were tested in the field and compound 3 had a sexual role, attracting more females while 5 seemed to play an aggregation role, luring both sexes in the same proportion.
Evidence of an Aggregation Pheromone in Males of Metamasius spinolae (Coleoptera: Curculionidae)
TLDR
This study is the first report of such a pheromone system for this tropical species, and attraction responses in laboratory and field studies suggest that a male-produced aggregation phersomone is the prevalent mechanism of chemical communication among cactus weevils.
Response of Plum Curculio (Coleoptera: Curculionidae) to Odor-Baited Traps Near Woods
TLDR
It is concluded that panel or pyramid traps, or a combination, baited with benzaldehyde plus pheromone placed at borders of plum curculio overwintering sites can be a valuable tool for monitoring the beginning, peak, and end of adult immigration into apple orchards.
(R*,S*)-5-hydroxy-4-methyl-3-heptanone male-produced aggregation pheromone ofSitophilus oryzae (L.) andS. zeamais motsch
TLDR
Synthetic racemic pheromone was highly attractive to males and females of both rice and maize weevils, and both sexes of the granary weevil,S.

Evidence for male-produced aggregation pheromone in American palm weevil,Rhynchophorus palmarum (L.) (Coleoptera: Curculionidae):
TLDR
Field trapping of the American palm weevil showed that the combination of caged male APWs and palm stem was much more attractive to APWs of both sexes than palm stem alone, giving evidence for a male-produced aggregation pheromone in this species.
Uses of Opuntia species and the potential impact of Cactoblastis cactorum (Lepidoptera: Pyralidae) in Mexico
TLDR
Because most Opuntia species are thought to be susceptible to attack by the cactus moth, Cactoblastis cactorum (Berg), spread of this moth into Mexico would likely have significant economic and social impacts.
