Dominance of spotted stemborer Chilo partellusSwinhoe (Lepidoptera: Crambidae) over indigenous stemborer species in Africa's changing climates: ecological and thermal biology perspectives
Agricultural and Forest Entomology - Tập 19 Số 4 - Trang 344-356 - 2017
Reyard Mutamiswa, Frank Chidawanyika, Casper Nyamukondiwa
Abstract Africa hosts several economically significant lepidopteran cereal stemborer species belonging to the Crambidae, Noctuidae and Pyralidae families. The invasive spotted stemborer (Chilo partellus Swinhoe), which is native to Asia, is one of the most damaging cereal stemborers in Africa. The impact of C. partellus on indigenous stemborer species remains unclear, although recent work demonstr... hiện toàn bộ
Oviposition preference and larval survival of Diprion pini on Scots pine clones in relation to foliage characteristics
Agricultural and Forest Entomology - Tập 2 Số 3 - Trang 185-192 - 2000
F. Pasquier‐Barre, C. Géri, Francis Goussard, Marie‐Anne Auger‐Rozenberg, Patrick De Clercq
Summary1 When laying eggs, adult female Diprion pini discriminated between clones of Scots pine, Pinus sylvestris.2 Larval survival was affected by Scots pine clone but was not correlated with oviposition preference.3 Diprion pini laid most eggs on tougher needles of Scots pine.4 There was no evidence to suggest that D. pini is responding to the monoterpene composition of the foliage.
Temperature as a predictor of survival of the pine processionary moth in the Italian Alps
Agricultural and Forest Entomology - Tập 9 Số 1 - Trang 65-72 - 2007
Emiliano Buffo, Andrea Battisti, Michael Stastny, Stig Larsson
Abstract1 The pine processionary moth Thaumetopoea pityocampa is expanding its geographical range in Europe, as a consequence of enhanced winter survival under a warmer climate. A combination of daytime nest temperatures and night air temperatures determines the number of hours larvae are able to feed (hours above realized feeding threshold, RFT).2 We tested the RFT‐based model for survival across... hiện toàn bộ
Behavioural responses of wheat stem sawflies to wheat volatiles
Agricultural and Forest Entomology - Tập 10 Số 3 - Trang 245-253 - 2008
Dariusz Piesik, David K. Weaver, Justin B. Runyon, Micaela Buteler, Gavin Earl. Peck, Wendell L. Morrill
Abstract1 Adult wheat stem sawflies Cephus cinctus, pests of cultivated cereals that also infests wild grasses, migrate into wheat fields where they oviposit in elongating, succulent stems.2 Volatiles released by wheat plants at susceptible stages were analyzed to determine potential semiochemical compounds. Seven major compounds were identified and quantified.3 A Y‐tube bioassay was developed to ... hiện toàn bộ
Microdot technology for individual marking of small arthropods
Agricultural and Forest Entomology - Tập 14 Số 2 - Trang 171-175 - 2012
Michael R. Whitehead, Rod Peakall
Individual mark–release–recapture is an important method for gathering data on insect movement, although it is limited by the constraints of tagging small insects with individual information. Microdots, originally developed for covert security applications, are small polymer discs (diameter 0.5 mm) bearing up to 26 characters of information and have the potential as an alternative to the larger be... hiện toàn bộ
