ECONOMIC RETURNS TO THE BOLL WEEVIL ERADICATION PROGRAM [PDF]

open access: yes
The economic viability of the Boll Weevil Eradication program in Alabama, Florida, and Georgia is assessed based on a five-year survey of producers. Results indicate the program increases yield 100 pounds per acre. This implies a 19 percent internal rate

Degree of insecticide exposure and access to nectar impact survival of Trissolcus japonicus, a hymenopteran parasitoid, in flowering border strips

open access: yesAgricultural and Forest Entomology, EarlyView.
We applied three thiamethoxam spray treatments to buckwheat border strips: control (no nearby spray), drift (adjacent peach trees directly sprayed) and direct spray (buckwheat and peaches directly sprayed). Drift‐treated buckwheat received about 1.4% the amount of thiamethoxam as direct‐spray buckwheat. This amount has no lethal effects on parasitoids,

Attraction of Phoracantha mastersi (Coloeptera: Cerambycidae) to copulation‐associated olfactory stimuli

open access: yesAgricultural and Forest Entomology, EarlyView.
Damage caused by Phoracantha mastersi larvae are the primary cause of forest decline in Australia's subalpine forests. Behaviour of male adult beetles was tested in response to a suite of commercial semiochemicals and conspecifics engaged in active copulation within a Y‐maze.

Refuge by day, forage by night: Diel activity of vine weevil as characterised by smart monitoring

open access: yesAgricultural and Forest Entomology, EarlyView.
Vine weevil activity was monitored using a Smart trap, which recorded diel refuge‐seeking behaviour. Increasing light intensity triggered refuge seeking behaviour, while lower light intensity induced forage seeking activity. Understanding vine weevil diel activity can enhance early detection, which can improve the effectiveness of integrated pest ...

Efficient Refuge policies for Bt cotton in India [PDF]

open access: yes
This study examined the efficient refuge policies for Bt cotton for three cotton growing regions in India. This was accomplished by developing a single-pest, dual-toxin biological model simulating bollworm resistance to the Bt toxin and synthetic ...

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

Effect of Manual Topping on Insect Pest Incidence and Cotton Yield

open access: yesCrop Protection
Bollworms and sap-sucking insect pests are a significant constraint to cotton production in Africa. Manual topping of cotton plants, which consists of cutting off the top of the plant, i.e. the terminal bud of the main stem, is a promising alternative to chemical control by removing resources for certain pests or inducing plant defences. In this study,
