Department of Plant Protection Institute for Agricultural Sciences (ICA), Spanish National Research Council (CSIC), Serrano 115 Dpdo., Madrid28006, Spain.

The tomato Mi-1 gene mediates plant resistance to whitefly Bemisia tabaci, nematodes, and aphids. Other genes are also required for this resistance, and a model of interaction between the proteins encoded by these genes was proposed. Microarray analyses were used previously to identify genes involved in plant resistance to pests or pathogens, but scarcely in resistance to insects. Read More

Dominant symbiotic bacteria associated with wild medfly populations reveal a bacteriocin-like killing phenotype: a 'cold-case' study.

Bull Entomol Res 2019 Dec 9:1-6. Epub 2019 Dec 9.

Department of Life Sciences, via A. Moro 2, University of Siena, Siena-53100, Italy.

The gut of the agricultural pest Ceratitis capitata hosts a varied community of bacteria, mainly Enterobacteriaceae, that were implicated in several processes that increase the fitness of the insect. In this study, we investigated the antagonistic activity in vitro of Klebsiella oxytoca strains isolated in the 1990s from the alimentary tract of wild medflies collected from different varieties of fruit trees at diverse localities. Assays were carried out against reference strains (representative of Gram-negative and -positive bacterial species) of the American Type Culture Collection (ATCC). Read More

Does feeding on pollen grains affect the performance of (Acari: Phytoseiidae) during subsequent generations?

Bull Entomol Res 2019 Dec 9:1-8. Epub 2019 Dec 9.

Department of Plant Protection, Faculty of Agriculture, Shahrekord University, Shahrekord, Iran.

Diet is a critical component of the mass-rearing of biological control agents, but the impacts of diet are not always immediately obvious and can take several generations to manifest, resulting in poor survival, reproduction, and ability to kill prey under natural conditions. Our present study aimed to investigate the performance of a commercially-reared phytoseiid mite, Amblyseius swirskii, after four (G4) and six (G6) consecutive generations on pollen grains of two plant species, as well as its ability to find and kill its natural prey, Tetranychus urticae, after long-term rearing on each diet. We found no significant difference between the two diets in intrinsic and finite rates in G4. Read More

Vector dynamics predicts transmission dynamics: a simple, realistic and sensible approach for measuring malaria endemicity.

Bull Entomol Res 2019 Dec 9:1-9. Epub 2019 Dec 9.

Regional Medical Research Centre, Bhubaneswar, Odisha, India.

Entomological indicators such as vector density, distribution, biology and bionomics and their vectorial attributes are important parameters for measuring the pattern and intensity of malaria transmission. Although published articles provide evidence for the existence of associations between entomological indices and malaria transmission dynamics, none of them is able to establish a strong correlation. In order to address this issue, the present study aims to assess how malaria transmission is influenced and can be predicted by local major vector dynamics. Read More

A dual molecular and cytogenetic study was performed with the aim to improve the controversial systematic classification of some species of Lamiinae (Coleoptera: Cerambycidae). The karyotypes of species belonging to genera Morimus, Herophila, Dorcadion, Neodorcadion and Lamia share a number of characters, which differentiate them from other species, belonging to genera Phytoecia, Parmena and Monochamus. The karyotypes of the last three species comprise 20 chromosomes, mostly metacentric or sub-metacentric, as in the presumed Cerambycidae ancestors. Read More

Carriers and cutters: size-dependent caste polyethism in the tropical fire ant ().

Bull Entomol Res 2019 Nov 18:1-9. Epub 2019 Nov 18.

Department of Ecological Humanities, Providence University, 200, Sec. 7, Taiwan Boulevard, Shalu Dist., Taichung City 43301, Taiwan.

Body size is an important life-history trait in eusocial insects which plays a key role in colony fitness. The division of labour, represented by caste polyethism, correlates with divergent morphological traits. Size polymorphism has been noted in the tropical fire ant, Solenopsis geminata; however, little is known regarding the differences in the size distributions of workers performing foraging tasks.

Bull Entomol Res 2019 Nov 6:1-11. Epub 2019 Nov 6.

Instituto Nacional de Tecnología Agropecuaria, Ruta 12 - Km 1008 (3400), Corrientes, Argentina.

Tibraca limbativentris (Hemiptera: Pentatomidae) is a major pest in Neotropical rice agroecosystems. In autumn-winter, this pest takes refuge in rice stubble and in native vegetation, which allows it to re-colonize the crop during the rice growing season. However, it is still unknown whether this vegetation is a pest sink or is actually a natural trap that contributes to pest population biocontrol. Read More

Coinfection by and a fungal pathogen increases survival of Chagasic bugs: advice against a fungal control strategy.

Bull Entomol Res 2019 Nov 6:1-7. Epub 2019 Nov 6.

Departamento de Ecología Evolutiva, Instituto de Ecología, Universidad Nacional Autónoma de México, Apdo. P. 70-275, Circuito Exterior, Ciudad Universitaria, 04510 Coyoacán, Mexico City, Mexico.

Triatomine bugs carry the parasitic protozoa Trypanosoma cruzi, the causal agent of Chagas disease. It is known that both the parasite and entomopathogenic fungi can decrease bug survival, but the combined effect of both pathogens is not known, which is relevant for biological control purposes. Herein, the survival of the triatomine Meccus pallidipennis (Stal, 1872) was compared when it was coinfected with the fungus Metarhizium anisopliae (Metschnikoff) and T. Read More
