Nest-departure behaviour of gynes and drones in the invasive yellowjacket Vespula germanica (Hymenoptera: Vespidae) Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-08-12 Andrés S. Martínez, Natalia Rousselot, Juan C. Corley, Maité Masciocchi
Inbreeding costs can be high in haplodiploid hymenopterans due to their particular mechanism of sex determination (i.e., single-locus complementary sex-determination system, sl-CSD), as it can lead to the production of sterile males. Therefore, mechanisms contributing to reduced inbred matings can be beneficial. In this sense, asynchronous nest departure of sibling drones and gynes could reduce kin

Comparative characterization of microbiota between the sibling species of tea geometrid moth Ectropis obliqua Prout and E. grisescens Warren. Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-08-03 Zhibo Wang,Hong Li,Xiaogui Zhou,Meijun Tang,Liang Sun,Shuai Zhan,Qiang Xiao
For a wide range of insect species, the microbiota has potential roles in determining host developmental programme, immunity and reproductive biology. The tea geometrid moths Ectropis obliqua and E. grisescens are two closely related species that mainly feed on tea leaves. Although they can mate, infertile hybrids are produced. Therefore, these species provide a pair of model species for studying the

Frass produced by the primary pest Rhyzopertha dominica supports the population growth of the secondary stored product pests Oryzaephilus surinamensis, Tribolium castaneum, and T. confusum Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-08-03 J.A. Shah, T. Vendl, R. Aulicky, V. Stejskal
Primary pests such as Rhyzoperta dominica may increase the contents of dockage, dust, and frass in grain mass. Although it has been suggested that frass can affect the population growth of stored product pests and ecological interactions among primary and secondary pests in stored grain, this has not been validated experimentally. Therefore, this work experimentally tested the hypothesis that R. dominica

Irradiation dose does not affect male reproductive organ size, sperm storage, and female remating propensity in Ceratitis capitata. Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-08-03 S Abraham,V Díaz,A Moyano,G Castillo,J Rull,L Suárez,A F Murúa,V Pantano,D Molina,S M Ovruski
The Mediterranean fruit fly Ceratitis capitata is a globally invasive pest, often controlled with the sterile insect technique (SIT). For the SIT, mass-rearing of the target insect followed by irradiation are imperatives. Sterile males are often less able to inhibit female remating and transfer less number of sperm, and even irradiation could affect male reproductive organs, with consequences for their

The attractant, but not the trap design, affects the capture of Drosophila suzukii in berry crops Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-07-17 Samuel Cruz-Esteban, Edith Garay-Serrano, Christian Rodríguez, Julio C. Rojas
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is recognized as an invasive pest in Europe and North America. In Mexico, it is one of the main insect pests of soft-skinned fruits such as blueberries, strawberries, raspberries, blackberries, plums, and guava. Previous studies have shown that D. suzukii uses visual and chemical cues during host plant searching. This knowledge has been used to

Life history of aggression in Anastatus disparis (Hymenoptera: Eupelmidae) with extreme male–male combat Bull. Entomol. Res. (IF 1.814) Pub Date : 2020-07-17 Peng-Cheng Liu, De-Jun Hao, Wei Hu, Jian-Rong Wei, Jian-Jun Wang
Aggressive behaviour is common in animals and typically has lifetime consequences. As younger males have higher residual reproductive value than older males and lose more from injuries than older males do, the propensity for fighting tends to increase with age in many empirical reports and species. However, fighting patterns in those empirical reports cannot confirm the hypothesis that individuals
