Lecturer in Entomology at the Tasmanian Institute of Agriculture (The University of Tasmania).

I'm a nerd that is into understanding: insect behavior, generalist life histories, as well as how insects have influenced culture, technology, and history.
FINAL THOUGHTS. I'm still going to use GenAI, but I'm going to ask why it gives me the responses that it does more often. GenAI is a roleplayer, at times it appeared chipper, sycophantic, & remorseful (without ever directly saying it shouldn't have made 💩 up).

I dug deeper. Since #GenAI essentially "roleplays" responses I asked it about potential reputational harm if I used this false information. I agree with its responses.

I checked to make sure that both ChatGPT and I were using the same definition of terms. then asked WHY I were given dubious claims.

It turns out that real elements were blended with "illustrative" (but false) details.

After asking for references for this "real" example, I was told that there were no references.

I started by asking for real examples of a farmer that uses technology to manage insects, then refined my question to specify an Australian example. I given the name of a real farmer, a bold claim of a 50%reduction in #insecticide use. Without references.

While "mop-top" refers to a distinct deformation of the leaves, sometimes associated with bright yellow v-shaped marks, foliar symptoms are not always present. More often inside the tubers have dark discolored rings. It can be mistaken for other potato diseases. - buff.ly/bxW2jXL

From wildlands to farmlands, we need to put functional roles front & centre.
Insect functional diversity supports pollination, pest control, nutrient cycling, & more.

Let’s design systems—conservation & agricultural—that work with insects, not without them. #Agroecology #InsectConservation

We can’t afford to forget insects when managing land—especially not on farms.

Across >5000 studies, diversified farming practices increased functional diversity and ecosystem services—without reducing yields.

But insects—the champions of ecosystem function—are too often overlooked in conservation planning.

Drawing on 20 years of community data, Rodrigues et al. found that functional trait composition—not just the number of species—is key to predicting how ecosystems respond to change.

It’s a reminder: biodiversity is about what organisms do.
