Thermal Tolerance of the Coffee Berry Borer Hypothenemus hampei: Predictions of Climate Change Impact on a Tropical Insect Pest
The thermal tolerance of the coffee berry borer, Hypothenemus hampei, the most devastating pest of coffee worldwide, is determined and inferences on the possible effects of climate change using climatic data from Colombia, Kenya, Tanzania, and Ethiopia are made.
Intraguild Predation among the Hoverfly Episyrphus balteatus de Geer (Diptera: Syrphidae) and Other Aphidophagous Predators
It is suggested that combinations of predators must be carefully chosen for success in biological control of aphids where more than one predator species is present.
Prey finding by larvae and adult females of Episyrphus balteatus
The prey‐location behaviour of larvae of Episyrphus balteatus DeG. (Dipt.: Syrphidae) was investigated in two different experimental set‐ups. First instar larvae exhibited directed search over short…

Transmission efficiency did not significantly differ between adult males and females, irrespective of the larval stage at which the virus was acquired, and the spread of CaCV on tomato plants in greenhouses showed a close association with thrips infestations.
The edaphic phase in the ontogenesis of Frankliniella occidentalis and comparison of Hypoaspis miles and Hypoaspis aculeifer as predators of soil-dwelling thrips stages
Predation capacity of two predatory laelapid mites on soil‐dwelling thrips stages
The fitness of the two predatory mites on F. occidentalis as prey and their suitability as biocontrol agents are elucidated.
Relationship between Management Practices, Fungal Infection and Aflatoxin for Stored Maize in Benin
Practices that reduced aflatoxin contamination were: planting improved varieties in northern Benin, mixed cropping with vegetables, use of NPK-fertilizer, drying of harvested cobs for 60-90 days, drying ears without the husk, sorting out of poor quality ears.
Laboratory investigations on the potential of entomopathogenic fungi for biocontrol of Helicoverpa armigera (Lepidoptera: Noctuidae) larvae and pupae
The susceptibility of third instar Helicoverpa armigera to seven strains of three entomopathogenic fungal species, i.e. Metarhizium anisopliae, Beauveria bassiana and Paecilomyces fumosoroseus, was tested under laboratory conditions using the larval immersion method to characterize the age-dependent mortality of different larval stages.
