Compatibility of the fungus Beauveria bassiana and Trichoplusia ni SNPV against the cabbage looper Trichoplusia ni: crop plant matters

Pest Management Science, Volume 80, Issue 6, Page 2851-2859, June 2024.
The combined application of a baculovirus (Trichoplusia ni Hübner (Lepidoptera: Noctuidae), T. ni single nucleopolyhedrovirus, TniSNPV) and Beauveria bassiana against the cabbage looper Trichoplusia ni was not more effective compared to singly applied TniSPNV.

A tropical extremal problem with nonlinear objective function and linear inequality constraints [PDF]

, 2012
We consider a multidimensional extremal problem formulated in terms of tropical mathematics. The problem is to minimize a nonlinear objective function, which is defined on a finite-dimensional semimodule over an idempotent semifield, subject to linear ...

Intermediate‐tier options in the environmental risk assessment of plant protection products for soil invertebrates—Synthesis of a workshop

Integrated Environmental Assessment and Management, Volume 20, Issue 3, Page 780-793, May 2024.
The introduction of intermediate tiers in the environmental risk assessment of plant protection products for soil organisms can help to reduce uncertainties in the risk assessment and serve as a bridge between the Tier 1 and higher‐tier risk assessment.

Complete solution of a constrained tropical optimization problem with application to location analysis

, 2014
We present a multidimensional optimization problem that is formulated and solved in the tropical mathematics setting. The problem consists of minimizing a nonlinear objective function defined on vectors over an idempotent semifield by means of a ...

Quantifying the impact of Psylliodes chrysocephala injury on the productivity of oilseed rape

Pest Management Science, Volume 80, Issue 5, Page 2383-2392, May 2024.
The impact of Psylliodes chrysocephala adult and larval damage on oilseed rape yield was quantified to help develop improved thresholds for Integrated Pest Management. Up to 90% leaf area loss (simulated using a hole punch) during early growth did not affect yield.

MUBs inequivalence and affine planes

, 2011
There are fairly large families of unitarily inequivalent complete sets of N+1 mutually unbiased bases (MUBs) in C^N for various prime powers N. The number of such sets is not bounded above by any polynomial as a function of N.

Experimental arena settings might lead to misinterpretation of movement properties

Insect Science, Volume 31, Issue 1, Page 271-284, February 2024.
Many studies examine movement in the laboratory and use different laboratory conditions, specifically arenas differing in structure, size, and shape. We examined the effect of the arena structure on movement properties using the red flour beetle as a model. The arena structure greatly affected movement properties, such as movement distance, turn angles,

Evaluating a new aphid biocontrol agent: The role of aphid density in modulating oviposition behaviour in the American hoverfly, Eupeodes americanus, and the aphid midge, Aphidoletes aphidimyza

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.

LEADER (Leaf Element Accumulation from DEep Roots): A nondestructive phenotyping platform to estimate rooting depth in the field

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.
