An Analysis of Longan Honey from Taiwan and Thailand Using Flow Cytometry and Physicochemical Analysis.

The increase in honey fraud in the global market has highlighted the importance of pollen analysis in determining or confirming the botanical and geographical origins of honey. Numerous studies are currently underway to develop efficient and rapid methods for the determination of the quality, botanical, and geographical origin of honey. Typically, the physicochemical analysis of honey is used to evaluate its quality and geographical source.

Oviposition Preferences of the Fall Armyworm () (Lepidoptera: Noctuidae) in Response to Various Potential Repellent and Attractant Plants.

The fall armyworm (FAW), , is a major polyphagous pest that mainly feeds on maize and other cash crops. Understanding 's behavior on different host plants facilitates the development of effective integrated pest management (IPM) plans. Therefore, this study investigated the oviposition preferences of females among different host plants using no-choice, two-choice, and multiple-choice bioassays.

Invasive Ant Detection: Evaluating Honeybee Learning and Discrimination Abilities for Detecting Odor.

Invasive red imported fire ants () create a serious threat to public safety, agriculture, biodiversity, and the local economy, necessitating early detection and surveillance, which are currently time-consuming and dependent on the inspector's expertise. This study marks an initial investigation into the potential of honeybees () to detect and discriminate the odor of through the olfactory conditioning of proboscis extension responses. Deceased were used as conditioned stimuli to ensure relevance to non-infested areas.

Biology, distribution, and management of invasive South American tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera; Gelechiidae), in Asia.

South American tomato leafminer, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae), is native to South America, but is a major invasive and quarantine pest species in Europe, Africa, and Asia. It causes extensive damage of up to 100% yield loss in tomatoes (Solanum lycopersicum) in open and greenhouse conditions. Since its first invasion in Spain in 2006, it has spread rapidly into many countries in the Mediterranean and Western Europe and further invaded Africa and Asia.

Toxicity and repellency of compounds from clove (Syzygium aromaticum) to red imported fire ants Solenopsis invicta (Hymenoptera: Formicidae).

The toxicity and repellency of the bioactive chemicals of clove (Syzygium aromaticum) powder, eugenol, eugenol acetate, and beta-caryophyllene were evaluated against workers of the red imported fire ant, Solenopsis invicta Buren. Clove powder applied at 3 and 12 mg/cm2 provided 100% ant mortality within 6 h, and repelled 99% within 3 h. Eugenol was the fastest acting compound against red imported fire ant compared with eugenol acetate, beta-caryophyllene, and clove oil.

Efficacy of natural products against Callosobruchus chinensis (Coleoptera: Bruchidae) in Nepal.

This study was conducted to determine the efficacy of local natural products against the beetle, Callosobruchus chinensis L. (Coleoptera: Bruchidae), in stored chickpea Cicer arietinum L. (Fabaceae) in Chitwan, Nepal.

Determining the most effective concentration of cypermethrin and the appropriate carrier particle size for fire ant (Hymenoptera: Formicidae) bait.

Background: The purpose of this study was to determine the most effective particle size of DDGS (distiller's dried grains with solubles) as fire ant bait carrier, as well as the most effective concentration of cypermethrin as a toxicant against the red imported fire ant (RIFA) Solenopsis invicta Buren under laboratory conditions.

Results: The DDGS particle size did not affect the fire ant's preference for the bait, but it did affect the mass of DDGS being carried back to the nest. The size of the DDGS particles and the mass of DDGS being carried back to the nest were positively correlated.

Efficacy of Beauveria bassiana against the red imported fire ant, Solenopsis invicta (Hymenoptera: Formicidae), in Taiwan.

Background: Combining biological control and chemical control could be used for controlling red imported fire ant (RIFA), Solenopsis invicta, more effectively. Beauveria bassiana F256, a local strain from Taiwan, was evaluated for its efficacy in the control of S. invicta under both laboratory and field conditions.

Interspecific competition between Solenopsis invicta and two native ant species, Pheidole fervens and Monomorium chinense.

This study was designed to understand the effects of the interspecific competition between red imported fire ant, Solenopsis invicta Buren and two native ant species, Pheidole fervens Smith and Monomorium chinense Santschi, by conducting colony interference and individual confrontation tests under laboratory conditions. The colony interference test showed that both native ant species, owing to their numerical advantage, killed the Solenopsis invicta virus-1 (SINV-1)-infected or healthy queens of S. invicta.

A new fire ant (Hymenoptera: Formicidae) bait base carrier for moist conditions.

Background: A new water-resistant fire ant bait (T-bait; cypermethrin 0.128%) consisting of dried distillers grains with solubles (DDGS) as a carrier was developed and evaluated against a standard commercial bait (Advion; indoxacarb 0.045%) under both laboratory and field conditions.
