Bedeutung und Bekämpfung von Schadinsekten an Winterweizen und Winterraps in Schleswig-Holstein, 1999-2001, und der Trend der Insektizid-Behandlungen von 1999-2004 [PDF]
, 2008 In the average of 1999 to 2004 winter wheat covered 64 % of the agricultural land of Schleswig-Holstein (331.000 ha), winter oilseed rape 31 %. These two important crops (covering 95 % of the acreage) were attacked in 1999 to 2001 by a) wheat: cereal ...

Reduced fertilization regimes could boost biocontrol service without reducing crop yield
Insect Science, EarlyView.Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Assessing the host plants of the invasive apricot aphid, Myzus mumecola (Hemiptera: Aphididae)
Agricultural and Forest Entomology, EarlyView.We investigated the host plants of the invasive apricot aphid Myzus mumecola (Hemiptera: Aphididae), an emerging pest species in Europe, by combining molecular and ecological approaches. The winter host plant was confirmed as apricot by both methods.

Agricultural and Forest Entomology, EarlyView.The abundance and density of three common sycamore aphids increased under elevated CO2, although this was only statistically significant for Drepanosiphum platanoidis. The number of nymphs produced by individual D. platanoidis alates isolated in clip cages was not significantly affected, suggesting that population level response was not driven by ...

PRIRODZENÍ NEPRIATELIA DIURAPHIS NOXIA (STERNORRHYNCHA: APHIDIDAE) NA SLOVENSKU [PDF]
, 2009 A study from 2002 documented the occurrence of natural enemies (parasitoid wasps, predatory fl ies, entomopathogenic fungi) associated with colonies of the Russian wheat aphid, Diuraphis noxia (Kurdjumov, 1913) (Sternorrhyncha: Aphididae), in the spring ...

European Journal of Entomology, 2016 Aphis fabae and Myzus persicae (Hemiptera: Aphididae) are insect pests that damage sugar beet and bean crops. Both are responsible for losses in yield and transmission of viral diseases, and may be present on the same host at the same time.

Agricultural and Forest Entomology, EarlyView.Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.
