On the paradox of pesticides [PDF]

arXiv, 2013
The paradox of pesticides was observed experimentally, which says that pesticides may dramatically increase the population of a pest when the pest has a natural predator. Here we use a mathematical model to study the paradox. We find that the timing for the application of pesticides is crucial for the resurgence or non-resurgence of the pests.

Gut Microbiota Mediate Insecticide Resistance in the Diamondback Moth, Plutella xylostella (L.)

Frontiers in Microbiology, 2018
The development of insecticide resistance in insect pests is a worldwide concern and elucidating the underlying mechanisms is critical for effective crop protection.

Biological Control of the Asian Citrus Psyllid

EDIS, 2021
Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies.

Dynamics and control of maize infection by Busseola fusca: multi-seasonal modeling and biocontrol strategies [PDF]

arXiv
Maize production in sub-Saharan Africa faces significant challenges due to the maize stalk borer (Busseola fusca), a major pest that causes substantial yield losses. Chemical control methods have raised concerns about environmental impact and pest resistance, making biological control a promising alternative.

BIOLOGICAL CONTROL OF MAIZE PESTS

Maize is a staple food and third most preferred coarse grain after wheat, rice providing a substantial amount of energy and micronutrients for much of India's population. India ranks 7th in maize production among the maize-producing countries worldwide.

Interfacial Photoelectrochemistry in Organic Synthesis

Angewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.

Global stability and optimisation of a general impulsive biological control model [PDF]

arXiv, 2008
An impulsive model of augmentative biological control consisting of a general continuous predator-prey model in ordinary differential equations augmented by a discrete part describing periodic introductions of predators is considered. It is shown that there exists an invariant periodic solution that corresponds to prey eradication and a condition ...

Spider Eye Development Editing and Silk Fiber Engineering Using CRISPR‐Cas

Angewandte Chemie International Edition, EarlyView.
Spiders exhibit unique traits with significant implications for a diversity of fields, and gene editing provides new opportunities for advancing research in these areas. In this study, we developed a CRISPR‐Cas9 protocol for spiders, enabling gene knock‐outs/knock‐ins to study gene function and introduce new phenotypic traits. Abstract CRISPR‐Cas9 gene

Predator interference effects on biological control: The "paradox" of the generalist predator revisited [PDF]

arXiv, 2015
An interesting conundrum in biological control questions the efficiency of generalist predators as biological control agents. Theory suggests, generalist predators are poor agents for biological control, primarily due to mutual interference. However field evidence shows they are actually quite effective in regulating pest densities.
