Male-Specific Volatiles Released by the Big Avocado Seed Weevil Heilipus lauri Boheman (Coleoptera: Curculionidae)

Profile of Terpenoid Compounds Mediating a Plant‐Herbivore Interaction: Screening by Static Headspace Solid‐Phase Microextraction‐Gas Chromatography/Q‐ToF Mass Spectrometry

“…However, the extracted ion chromatogram proved convincingly the occurrence of P‐AL in most extracts of female C. dimidiatus . A comparison with the P‐AL peak intensity in the current work and in the male microextractions from C. psidii and Heilipus lauri is not possible because the intensity scale of the chromatograms is omitted in those publications [10,12] …”

“…A comparison with the P-AL peak intensity in the current work and in the male microextractions from C. psidii and Heilipus lauri is not possible because the intensity scale of the chromatograms is omitted in those publications. [10,12] It is known that in many insect species, mating status influences production and response to sex pheromones. [38] For example, only virgin female D. armandi produces frontalin as the mated male.…”

“…[10 -13] Romero-Frías, for example, obtained the same information about the presence of two insect pheromones by using SHS-SPME-GC/MS and the classical dynamic aeration (dynamic headspace DHS) method. [10,12] Chemical ecology is concerned, among other things, with the study of the relationship between an insect and its host plant and balances pest control strategy with research into insect interactions, requiring first the knowledge of the identity of the metabolites and then, the amounts released by them. Authors reported β-caryophyllene, limonene, and copaene as the main volatile organic compounds involved in the signalization between Conotrachelus psidii Marshall and its host, the Colombian guava.…”

“…Review articles have been written abundantly on different aspects of solid phase microextraction (SPME) because its current applicability due to two reasons: the matrix complexity and the low concentrations of the analytes in a variety of research trends [8] . Moreover, static headspace SPME coupled to gas chromatography‐mass spectrometry (SHS‐SPME‐GC/MS) has become the ideal method for in vivo sampling of endogenous substances of insects [9] and their emissions [10–13] . Romero‐Frías, for example, obtained the same information about the presence of two insect pheromones by using SHS‐SPME‐GC/MS and the classical dynamic aeration (dynamic headspace DHS) method [10,12] …”

Grandisol as an attractant for the sugar beet pest Bothynoderes affinis and data on other Lixinae species

“…To the best of our knowledge, this is the first report about an attractant for this species. The racemic grandisol or its (1 R ,2 S )‐enantiomer is an aggregation pheromone component of the boll weevil A. grandis (Tumlinson et al, ) and other curculionid species including several pine weevils of genus Pissodes (Booth et al, ; Phillips et al, ; Hibbard & Webster, ; Ze et al, ; Marques et al, ), the soybean stalk weevil, Sternechus subsignatus Boheman (Ambrogi et al, ), the cocoa borer, Conotrachelus humeropictus Fiedler (Szczerbowski et al, ), Homalinotus validus (Olivier) (Vidal et al, ), the avocado seed weevil, Heilipus lauri Boheman (Romero‐Frías et al, ), the pecan weevil, Curculio caryae (Horn) (Hedin et al, ), the strawberry blossom weevil, Anthonomus rubi (Herbst) (Innocenzi et al, ), Pseudopiazurus obesus (Boheman) (Zarbin et al, , ), and four bark beetles species – Pityophthorus pityographus (Ratzeburg) (Francke et al, ), Pityogenes bidentatus (Herbst) (Francke et al, ; Byers et al, ), Pityogenes calcaratus (Eichhoff) (Francke et al, ), and Polygraphus punctifrons Thomson (Rahmani et al, ). The current study demonstrated that grandisol also attracted A. punctiventris .…”
