The larvae emerge…

It’s that time of year again when a new cohort of enthusiastic entomologists begin their journeys at Harper Adams, which of course means new authorship of Mastering Entomology. So, this short post is going to introduce us as the new authors and let you know what you can expect from us across the next year.

We’ve written short pieces introducing ourselves:

Hi guys! My name is Aqib Ali and I am one of two curators of this blog, for this academic year. I’ve had an interest in “creepy crawlies” from a very young age. It began with a childish, albeit slightly morbid, curiosity (yes, I was one of those pulling-off-legs and offering-sacrificial-larvae-to-spider-overlords kind of kids). Although, this interest faded slightly as I moved through the mundane secondary school system, my love for life sciences remained constant and it led to me doing a BSc (Hons) Zoology degree at the University of Derby. As I passed through my undergraduate course, my passion for all things insect was slowly reignited. I did several modules with entomological content, one of which was “Applied Entomology”, taught by the likes of Professor Karim Vahed- a leading expert in the field of sexual selection and insects. With my interests piqued, I decided to do a dissertation on an aspect of sexual selection, namely intrasexual selection (male competition). I looked at whether weapon size affects the outcome of aggressive encounters in a cricket species (Platygryllus primiformis). I also sought out volunteering, such as a research assistant for forensic entomologist Dr. Kate Barnes, to broaden my entomological interests. By the end of my undergraduate degree my heart and head were both set on carrying on down the entomological path. Deciding what my next step would be was a no brainer: the MSc Entomology course at Harper Adams University. What attracted me to this course was its range of modules which cover a variety of topics, the excellent teaching quality and facilities, and that it’s quite literally one of a kind.

My entomological interests at this stage are broad and I am open to the many aspects of this diverse subject. Entering this course open-minded will allow me to fully experience and consider my options before I find my specialism. This journey has started with a bang with the Biology and Taxonomy module! In the short time, I’ve been here I’ve learnt so much! I hope to carry on learning new things, acquiring invaluable skills, amassing great experiences and most importantly, loving what I do.”- Aqib Ali

The new cohort, learning some practical skills in Biology and Taxonomy of Insects (Photo by Aqib)

 

Hi I’m Linzi and I’m a graduate from Keele University studying Applied Environmental Science with Physical Geography. My interest in entomology began when we used aquatic insects as indicator species during a field trip to Cwm Idwal. This developed further throughout more field trips around Staffordshire and into France. When it came to my final year I selected modules that would allow me to focus my interests more and decided to base my dissertation on insects.

After hours of scouring news articles and journal articles I decided to investigate pesticide contamination in honey, particularly neonicotinoids. Although by the end of my experimental work I ended up looking for 91 different pesticides across five honey samples. I loved my dissertation and really wanted to take it further, this is what really set my mind on entomology. Hours and hours of reading articles about honey bees, and other beneficial pollinators had me captivated and after a short google search, my heart was set on Harper.

I have been lucky to be given the opportunity to study at Harper, and since arriving only three weeks ago I’ve already learnt so much and my interests have greatly broadened! I’m excited to keep broadening my interests and eventually find the area that I will  have a career in.Linzi Jay Thompson

So…that’s us! We will be publishing a variety of articles covering; our course, our interests and more. We aim to publish as regularly as possible (schedule permitting) so check back to see which exciting article we have posted. You can expect up to three articles per month covering a variety of topics, meanwhile, please follow us on twitter @EntoMasters for the latest updates, and follow our personal twitter accounts too @EntoAqib and @Apis_Linzi.

MRP: Optimising rearing conditions for black solider flies – Julian Beniers

Julian Beniers is a man with a mission. Before he even applied for the MSc course, he had formulated his Master’s Research Project (MRP), methods and all. During his BSc at HAS University of Applied Sciences, he started a project on black solider flies (Hermetia illucens) and became interested in their biology and behaviour. He then furthered this interest when doing an internship with the same species before coming to Harper Adams University (twitter: @HarperAdamsUni). By the time he arrived in Shropshire, his MRP was complete in all but execution.

Julian will be investigating the effect of protein and carbohydrate levels in black solider fly larvae foods and its relation to larval mass over the course of larval development, and potentially macronutrient levels within the larvae too (time permitting). He wants to answer the question “When do black soldier fly larvae begin producing large fat reserves, and specifically, at what weight does this normally occur?”. Black solider fly larvae rapidly become larger during their first instars and protein is likely to the most important macronutrient of their diet, whereas later in larval development, carbohydrates and fats may become more important. To answer his research question, Julian will attempt to map protein and fat content of larvae at precise intervals throughout their development by killing, drying and subjecting the dried tissue to Soxhlet and leco fat and protein analysis, respectively. He’ll also be using a variety of different foods with varying levels of protein and carbohydrate to see if these can be used to determine an optimal diet and growth rate. He suspects the larval mass at which a change in macronutrient storage occurs in between 140-160 mg.

This research is potentially quite commercially important because of the widespread use of black soldier fly larvae in the pet trade (food for exotic pets) and in human entomophagy (food for us). Interestingly, Julian gently suggests that this research may actually have been done before internally within pet food companies, however, as the Robin Hood of trade secrets, Julian attempts to get this research published, which could make things easier for other companies and independent rearers.

More generally, Julian is an avid keeper of entomofauna and is curious about the upcoming entomophagy industry in the West (an age-old industry in other parts of the world); he is planning to attend the Royal Entomological Society’s entomophagy day on April 4th.

Please don’t hesitate to contact me (details below) or Julian with advice or questions (twitter: @Julianosaurus; email: julianbeniers@hotmail.com; LinkedIn).

Master’s Research Project: methods of sampling ant-associated beetles – Jack Weatherington

The ecological dominance of ants (Hymenoptera: Formicidae) is striking across a very wide spatial scale, reaching its pinnacle in the rainforests and savannahs of the tropics (Hölldobler and Wilson, 1990). The jurisdiction of this Queendom reaches Britain too. Red wood ants (Formica rufa), where found, can constitute a vital part of the local ecology of forests, feeding on aphid honeydew and pretty much any invertebrates they can overpower, like the little myrmidons they are. Jack Weatherington, a fellow MSc student boasting an impressive knowledge of insect taxonomy, has chosen the red wood ant as the focus for his Master’s Research Project (MRP). However, he faced a dilemma! Continue reading

Insect flight – an evolutionary development that shaped the world

Flying animals have had a major impact on nonflying organisms. Briefly consider the ecological and evolutionary interrelationships between pollinators and flowers, or between mosquitoes, the parasites they transmit and humans. Even a cursory glance at the manifold relationships flying insects have with all other forms of terrestrial life evaporates any doubt whether the world would be a very different place if they had never evolved.

Parenting for Dummies (feat. burying beetles)

Festive greetings readership,

On a gloomy, mist-filled night, the life of a mouse is gently extinguished by disease. Its blood stills, its body cools, and a slight wind carries its almost imperceptible scent through the air. A faint buzzing approaches from the darkness, growing louder and louder; a flash of jet-black and red in the moonlight. Another. Then… silence. Two beetles scamper onto the carcass after their nightly flights. They are burying beetles, a male and a female, and have much to do over the next 2-3 weeks. Continue reading

Night takes Queen: where do all the wasps go in winter?

Season’s greetings readership,

As I type, millions of Vespula vulgaris (‘common wasp’) queens are in a deep slumber within dead logs, sheds, attic spaces, burrows, and innumerable other areas out of the British elements. Because all other members of a wasp colony die over winter, the survival of the queen is vital to regenerate populations in the spring and summer. But this process is far from simple, incorporating physiological and behavioural adaptations that must be timed accurately to prevent freezing, parasitism, predation,and starvation. The journey of a queen wasp is quite an incredible one involving death, opposition, sex, family, altruism, resurrection, and prejudice, and I would like to personally recommend it as a superior alternative to the biblical prose to which we are flooded at this time of year.
