Journal of Applied Entomology, Volume 148, Issue 1, Page 5-12, February 2024.Abstract Hoverfly larvae are voracious predators of aphids but have limited dispersal capacity, so their survival depends critically on female selection of oviposition sites. For aphid control purposes, the ability of females to find small aphid colonies is especially valuable.

On the multiplication groups of semifields
European Journal of Combinatorics, 2010 The multiplication group of a loop is the permutation group generated by all right and left multiplications of the loop. The author uses finite semifields (i.e. non-associative division algebras) to obtain loops whose multiplication groups are between \(\text{PSL}(n,q)\) and \(\text{PGL}(n,q)\), for \(n\geq 3 \) and \(q^n>8\); the proof is based on ...

Breaking the beetle barrier: Innovative strategies for controlling Hylurgus ligniperda in China
Ecotoxicology and Environmental SafetyHylurgus ligniperda is a major quarantine pest of forest trees in China. Exploring emergency control techniques in the field can effectively avoid large outbreaks and the spread of H. ligniperda. In this study, H.

Non-Apis bees as model organisms in laboratory, semi-field and field experiments
Journal für Kulturpflanzen, 2020 As part of the registration process of plant protection products (PPPs) and their active substances in the EU, the risk of PPPs for bees has been assessed so far by using the European honey bee (Apis mellifera L.) as a surrogate species.

Crop Science, Volume 64, Issue 1, Page 333-353, January/February 2024.Abstract Deeper rooted crops are an avenue to increase plant water and nitrogen uptake under limiting conditions and increase long‐term soil carbon storage. Measuring rooting depth, however, is challenging due to the destructive, laborious, or imprecise methods that are currently available.

Central Weak Nucleus Semifields
European Journal of Combinatorics, 1981 Using results of S. D. Cohen and the author, we characterize certain infinite families of finite semifields. This yields several infinite families of finite projective planes, all of which have order a power of 3, and which appear to be previously unknown.

On the autotopism group of the Cordero-Figueroa semifield of order 3⁶ [PDF]
, 2016 In [5] M. Biliotti, V. Jha and N. Johnson were able to completely determine the autotopism group of a generalized twisted field as a subgroup of ΓL(K) × ΓL(K), where K = GF(pⁿ) and ΓL(K) is the group of nonsingular semilinear transformations over K.

Alternative locust control with a dilutable linseed oil emulsion
Food and Energy Security, Volume 13, Issue 1, January/February 2024.In this study, we improved a pesticidal formulation based on linseed oil for the control of gregarious locusts. Lab experiments and a semifield experiment conducted with Schistocerca gregaria revealed a high toxicity of this oil emulsion. This emulsion is harmless for humans and biodegradable.
