Christopher Cutler2 · N. Kirk Hillier1 Received: 21 September 2019 / Accepted: 8 July 2020 © Springer Nature Switzerland AG 2020 Abstract Olfaction is a key sensory modality for many arthropods and could be used as a tool in pest management through manipulation of pest behavior. Management of Varroa destructor, important parasitic mites of honey bees, could be improved through better understanding of the chemical ecology of this host-parasite relationship. We refned techniques of mount- ing mites to obtain electrophysiological recordings (electrotarsograms) of their responses to synthetic odor stimuli. Results of 271 electrotarsogram recordings from V. destructor revealed responses to 10 odorants relative to solvent controls. Electrotarsogram responses to methyl palmitate, ethyl palmitate, and 2-heptanol were highest at the lowest stimulus loading (10 ng) we tested, suggesting that V. destructor may have acute sensitivity to low concentrations of some odors. Results suggest that odorant origin (e.g., methyl oleate from honey bee larvae, geraniol from adult honey bee alarm pheromone, and α-terpineol, a plant secondary metabolite) can infuence the degree of electrophysiological response. Varroa destructor tended to be more responsive to known attractants and repellents relative to previously unexplored odorants and some repellent terpenes. Electrotarsograms ofer the potential for screening odors to determine their importance in V. destructor host detection.

Thorough examination revealed maggots and punched-out round holes lesion around the perineal region. Complete blood counts (CBC) and serum biochemical examinations showed no remarkable findings except mild anemia and mild thrombocytosis. The diagnosis was easily done, based on clinical signs and maggots identification. Cleaning with chlorhexidine, povidone-iodine lavage and hair clipping away from the lesions were performed soon after presentation. SNAP 4Dx Test (IDEXX Laboratories, Westbrook, ME, USA) was performed to rule out other vector-borne diseases since the ticks were found on the clipped area and vector-borne pathogens. The test result was negative. The dog in this case was treated with ivermectin (300 mcg/kg SC) one time. Also, treatments with amoxicillin clavulanate (20 mg/kg PO, BID) was established to prevent secondary bacterial infections. Then, myiasis resolved with 2 weeks and the affected area was healed. Key words : Dog, Myiasis, Maggot, Ivermectin, Tick. Introduction Treatment of myiasis should include hair clipping and flushing around the lesions and cleaning with an antibacte- Myiasis is an uncommon parasitic infection of dogs and rial shampoo (10). -
The Circadian Rhythm and Visual Elements in Scorpions: a Review
Arthropods, 2013, 2(4): 150-158 Article The circadian rhythm and visual elements in scorpions: A review M. R. Warburg Dept. of Biology, Technion-Israel Institute of Technology, Haifa 32000, Israel E-mail: [email protected] Received 12 August 2013; Accepted 15 September 2013; Published online 1 December 2013 Abstract The purpose of this paper is to review the state of research in this field and to outline future ways how to proceed. The term: "Zeitgeber", implies ‘time giver’ meaning: synchronizer when an external entrainment factor synchronizes the endogenous rhythm. Is this ‘time’, the chronological date in the sense that it is related to the time of day as reflected in the natural light-dark cycles? Or does it mean cyclic phases of activity as demonstrated in the laboratory? Moreover, is it totally independent of the animal's physiological condition? This subject was studied largely in buthid species (15) of a total of only 30 scorpion species. Moreover, many (over 25%) of the studies (19) were done on a single buthid species: Androctonus australis. Species diversity was observed only by one author’s work who studied eye structure in seven species. Since he found variability in eye structure it would not be advisable to generalize. The fact that experimenting was carried out irrespective of species diversity, gender, ecological or physiological conditions, and was usually done on animals kept in captivity for some time before the experimenting had started, is a major drawback to this kind of study. The diurnal rhythms is triggered either directly through spontaneous arrhythmic activity in the central nervous system, or by neurosecretory material. -

Insect and Arachnid Collection Quest
INSECT AND ARACHNID COLLECTION QUEST This quest encourages you to explore and investigate what you might normally ignore. To complete this quest, find 10 different species of insects, at least one species of arachnids, preserve the insects and arachnids, and then pin your collection. Once you have completed these steps, label the parts of the insects and the arachnids. At the end of this quest, you will receive a “Critters of Texas” pocket guide and points to use toward the trade items at Texas Nature Traders. STEP 1: Identify and collect 10 different insect species. The collection should include five different families of insects. STEP 2: Identify and collect at least one species of arachnids. STEP 3: Perform the proper procurement and preservation methods. STEP 4: Properly pin insects and arachnids. STEP 5: Label parts of insects: head, thorax and abdomen. Label parts of arachnids: cephalothorax and abdomen. STEP 6: Bring in the collection to Texas Nature Traders. FUN FACTS AND ANSWERS TO CURIOUS QUESTIONS What is the difference between insects and arachnids? o Mostly anatomical, such as: arachnids lack antennae; insects have mandibles and arachnids have fangs; insects have six legs and arachnids have eight. Can insects hear? o Yes. Insects use sounds to communicate and navigate their environment. Most insects have a pair of tympanal organs. In many cases, there is also a receptor on the antennae called the Johnston’s organ, which also collects sound vibrations. Are insects/arachnids considered animals? o Yes, they belong to the kingdom Animalia. Where in the world has the most mosquitoes? o Alaska has the most mosquitoes due to the melting snow, which leaves large amounts of standing water – perfect conditions for mosquito breeding. -

Homeowner Guide to Scorpions and Their Relatives
HOMEOWNER Guide to by Edward John Bechinski, Dennis J. Schotzko, and Craig R. Baird CIS 1168 Scorpions and their relatives “Arachnid” is the scientific classification category for all eight-legged relatives of insects. Spiders are the biggest group of arachnids, with nearly 3800 species known from the U.S and Canada. But the arachnid category includes other types of eight-legged creatures that sometime cause concern. Some of Idaho’s non-spider arachnids – such as scorpions -- pose potential threats to human health. Two related non-spider arachnids – sun scorpions and pseudoscorpions – look fearsome but are entirely harmless. This publication will help you identify these three groups and understand the threats they pose. All three of these groups almost always are seen as lone individuals that do not require any control.

Diapause and Quiescence As Two Main Kinds of Dormancy and Their Significance in Life Cycles of Mites and Ticks (Chelicerata: Arachnida: Acari)
Acarina 17 (1): 3–32 © Acarina 2009 DIAPAUSE AND QUIESCENCE AS TWO MAIN KINDS OF DORMANCY AND THEIR SIGNIFICANCE IN LIFE CYCLES OF MITES AND TICKS (CHELICERATA: ARACHNIDA: ACARI). PART 2. PARASITIFORMES V. N. Belozerov Biological Research Institute, St. Petersburg State University, Peterhof 198504, Russia; e-mail: [email protected] ABSTRACT: Concerning the problem of life history and such an important its aspect as seasonality of life cycles and their control enabled by dormant stages, the parasitiform mites reveal the obvious similarity with the acariform mites. This concerns the pres- ence of both main kinds of dormancy (diapause and quiescence). The great importance in the seasonal control of life cycles in some parasitiform mites, like in acariform mites, belongs also for combinations of diapause with non-diapause arrests, particularly with the post-diapause quiescence (PDQ). This type of quiescence evoked after termination of diapause and enabling more accu- rate time-adjustment in recommencement of active development, is characteristic of both lineages of the Parasitiformes — Ixodida and Mesostigmata (particularly Gamasida). The available data show that in ixodid ticks the PDQ may be resulted similarly after developmental and behavioral diapause. Reproductive diapause combined with the PDQ is characteristic of some gamasid mites (particularly the family Phytoseiidae), while most gamasid and uropodid mites with phoretic dispersal reveal the dormant state (apparently of diapause nature) at the deutonymphal stage. The uncertainty between diapause and non-diapause dormancy is retained in some many cases (even in ixodid ticks and phytoseiid mites), and the necessity of further thorough study of different forms of diapause and non-diapause arrests in representatives of the Acari is noted therefore. -
Jump Takeoff in a Small Jumping Spider
Journal of Comparative Physiology A https://doi.org/10.1007/s00359-021-01473-7 ORIGINAL PAPER Jump takeof in a small jumping spider Erin E. Brandt1,2 · Yoshan Sasiharan2 · Damian O. Elias1 · Natasha Mhatre2 Received: 27 October 2020 / Revised: 4 February 2021 / Accepted: 23 February 2021 © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021 Abstract Jumping in animals presents an interesting locomotory strategy as it requires the generation of large forces and accurate timing. Jumping in arachnids is further complicated by their semi-hydraulic locomotion system. Among arachnids, jumping spiders (Family Salticidae) are agile and dexterous jumpers. However, less is known about jumping in small salticid species. Here we used Habronattus conjunctus, a small jumping spider (body length ~ 4.5 mm) to examine its jumping performance and compare it to that of other jumping spiders and insects. We also explored how legs are used during the takeof phase of jumps. Jumps were staged between two raised platforms. We analyzed jumping videos with DeepLabCut to track 21 points on the cephalothorax, abdomen, and legs. By analyzing leg liftof and extension patterns, we found evidence that H. conjunc- tus primarily uses the third legs to power jumps. We also found that H. conjunctus jumps achieve lower takeof speeds and accelerations than most other jumping arthropods, including other jumping spiders. Habronattus conjunctus takeof time was similar to other jumping arthropods of the same body mass. We discuss the mechanical benefts and drawbacks of a semi- hydraulic system of locomotion and consider how small spiders may extract dexterous jumps from this locomotor system. -
