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.

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.

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.

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.

Computational Explorations on Semifields
CoRRA finite semifield is a division algebra over a finite field where multiplication is not necessarily associative. We consider here the complexity of the multiplication in small semifields and finite field extensions. For this operation, the number of required base field multiplications is the tensor rank, or the multiplicative complexity.

Nature’s Solution to Aedes Vectors: Toxorhynchites as a Biocontrol Agent
Journal of Tropical Medicine, Volume 2024, Issue 1, 2024.This review summarizes the predatory potential of Toxorhynchites mosquitoes as biological control agents for Aedes vectors. A single larva can consume hundreds of mosquito larvae during its development, with preference for larger prey and higher consumption rates at higher prey densities.

∗‐π‐Reversible ∗‐Semirings and Their Applications to Generalized Inverses
Journal of Mathematics, Volume 2024, Issue 1, 2024.We introduce and study a new class of ∗‐semirings which is called ∗‐π‐reversible ∗‐semirings. A ∗‐semiring R is said to be ∗‐π‐reversible if for any a, b ∈ R, ab = 0 implies there exist two positive integers m and n such that bman∗=0. Some characterizations and examples of this class of semirings are given. As applications, generalized inverses related

The two sets of three semifields associated with a semifield flock [PDF]
Innovations in Incidence Geometry: Algebraic, Topological and Combinatorial, 2005 In 1965 Knuth showed that from a given finite semifield one can construct further semifields manipulating the corresponding cubical array, and obtain in total six semifields from the given one. In the case of a rank two commutative semifield (the semifields corresponding to a semifield flock) these semifields have been investigated by Ball and Brown ...
