Tritrophic Interactions Mediated By Zoophytophagous Predator-Induced Host Plant Volatiles, Bashiru Adams, Abdullahi Ahmed Yusuf, Baldwyn Torto, Fathiya Mbarak Khamis

All Peer-Reviewed Publications

The zoophytophagous mirid predator Nesidiocoris tenuis and the ectoparasitoid Stenomesius japonicus are important biological control agents for several agricultural pests including the invasive leafminer, Phthorimaea absoluta, a destructive pest of Solanaceous crops especially tomato in sub-Saharan Africa. However, little is known about how feeding by N. tenuis can influence the tritrophic interactions in the tomato plant. Here, we tested the hypothesis that N. tenuis phytophagy would influence the tritrophic olfactory interactions between the host plant tomato and pest, predator, and parasitoid. In olfactometer assays, P. absoluta females and N. tenuis adults were both attracted to constitutive volatiles released by the …


The Path To Greening Our Future, Havovi Joshi Nov 2024

The Path To Greening Our Future, Havovi Joshi

Asian Management Insights

More than half of humanity currently lives in urban areas, and the United Nations predicts that figure will reach 70 percent by 2050. Cities worldwide already generate a significant amount of solid waste annually, adding to vexing issues that the global community is trying to address–demand for transportation, air pollution, access to public open spaces, urban sprawl, and general sustainability challenges. Throw in global warming and the copious greenhouse gas (GHG) emissions borne of construction activities, and the challenge of creating the necessary urban infrastructure to cope comes into sharp focus.


Urban H: Housing, Heat, And Health, Loretta Lees Nov 2024

Urban H: Housing, Heat, And Health, Loretta Lees

Asian Management Insights

Future policy needs to triangulate the ‘triple-H’ to help marginalised urban populations.

1. The urban heat island effect generates disproportionately high temperatures in urban settlements compared to non-urban ones, leading to increased heat-related illnesses and mental health issues, especially among vulnerable and marginalised populations living in poorly-planned or -resourced areas.

The Urban-H research agenda by Boston University’s Initiative on Cities focuses on the interconnected effects of housing, heat, and health (triple-H) to develop a resilience index for cities.

3. The proposed global Urban-H Index could help cities worldwide address the triple-H crisis by guiding policymakers to craft equitable, as well …

Our Roads Are Choking Us, Mark Stevenson, Ferdinand Balfoort, Darius Balfoort

Asian Management Insights

Re-imagining transport systems to cut carbon emissions and drive climate change.

1. The global transport sector, particularly road transport, contributes significantly to global greenhouse gas (GHG) emissions and air pollution, causing serious health issues like respiratory and cardiovascular diseases, especially in highly urbanised areas.

2. In-vehicle telematics and smartphone apps that provide emission feedback can help incentivise drivers to adopt sustainable driving habits. A global carbon credit market can help achieve the same goal by letting individuals and companies monetise their emission reduction.

3. Transitioning to electric vehicles and micro- mobility solutions, with the support of proper infrastructure and regulations, …


Yellow Crazy Ant, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Yellow Crazy Ant, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

Yellow crazy ants (Anoplolepis gracilipes) are believed to be native to west Africa or Asia. They are not present in Western Australia (WA) and are prohibited.

Yellow crazy ants were first observed in Australia in the early 1900’s on the Cocos-Keeling Islands and Christmas Island, where they have now caused a massive decline in the population of iconic red crabs. More recently, they have been recorded in Queensland, the Northern Territory (NT), and New South Wales (NSW).


Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia Nov 2024

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.

Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.
