Malan1 (1) Department of Conservation Ecology, Stellenbosch University, Private Bag X1, Matieland (Stellenbosch), South Africa (2) Corteva AgriscienceTM, South Africa Submitted for publication: February 2020 Accepted for publication: May 2020 Key words: Agoma trimenii, grapevine, monitoring, Trimen’s false tiger moth Trimen’s false tiger moth, Agoma trimenii (Lepidoptera: Agaristidae), has recently been found to occur in vineyards in the Northern Cape and Limpopo (Groblersdal area) provinces of South Africa. As little is known about the biology and behaviour of the moth, no official monitoring methods or economic thresholds relating to it exist. Consequently, management and registered control options still require development. The first aim of the current review was to gather and critically discuss all the available information on A. trimenii in the context of the information gained from field observations conducted in the Northern Cape during the 2016/2017 and 2017/2018 seasons. The paper also includes reporting on field observations made with regard to various aspects of the seasonal life cycle and ecology of A. trimenii, with a view to investigate, in future research, the potential biological control options available. Potential monitoring strategies of A. trimenii in the field were investigated. Various life stages of A. trimenii were identified, peak flight times were established, overlapping generations were determined, and the behavioural traits of all life stages were documented. Ultraviolet blue light traps proved to be the most promising potential monitoring strategy, with the prospect for an A. trimenii pheromone lure holding potential as an alternative monitoring strategy in the future. In summarising all current information on A. trimenii, recommendations for growers to monitor and control A. trimenii are presented towards the development of an integrated pest management system for the moth. INTRODUCTION South Africa is a major contributor to the worldwide export Knowledge relating to the biology and life cycle of of table grapes, having produced an estimate of 59.4 million A. trimenii is limited, and consequently there is a need for cartons during the 2018/2019 season (SATI, 2019).

This Just-IN manuscript is the accepted prior to copy editing and page composition. It may differ from final official version of record. Page 2 of 44 Abstract Many of the arthropod species that are important pests of agriculture and forestry are impossible to discriminate morphologically throughout all of their life stages. Some cannot be differentiated at any life stage. Over the past decade, DNA barcoding has gained increasing adoption as a tool to both identify known species and to reveal cryptic taxa. Although there has not been a focused effort to develop a barcode library for them, reference sequences are now available for 77% of the 409 species of arthropods documented on major pest databases. Aside from developing the reference library needed to guide specimen identifications, past barcode studies have revealed that a significant fraction of arthropod pests are a complex of allied taxa. Because of their importance as pests and disease vectors impacting global agriculture and forestry, DNA barcode results on these arthropods have significant implications for quarantine detection, regulation, and management.

  • African Butterfly News Can Be Downloaded Here
    LATE SUMMER EDITION: JANUARY / AFRICAN FEBRUARY 2018 - 1 BUTTERFLY THE LEPIDOPTERISTS’ SOCIETY OF AFRICA NEWS LATEST NEWS Welcome to the first newsletter of 2018! I trust you all have returned safely from your December break (assuming you had one!) and are getting into the swing of 2018? With few exceptions, 2017 was a very poor year butterfly-wise, at least in South Africa. The drought continues to have a very negative impact on our hobby, but here’s hoping that 2018 will be better! Braving the Great Karoo and Noorsveld (Mark Williams) In the first week of November 2017 Jeremy Dobson and I headed off south from Egoli, at the crack of dawn, for the ‘Harde Karoo’. (Is there a ‘Soft Karoo’?) We had a very flexible plan for the six-day trip, not even having booked any overnight accommodation. We figured that finding a place to commune with Uncle Morpheus every night would not be a problem because all the kids were at school. As it turned out we did not have to spend a night trying to kip in the Pajero – my snoring would have driven Jeremy nuts ... Friday 3 November The main purpose of the trip was to survey two quadrants for the Karoo BioGaps Project. One of these was on the farm Lushof, 10 km west of Loxton, and the other was Taaiboschkloof, about 50 km south-east of Loxton. The 1 000 km drive, via Kimberley, to Loxton was accompanied by hot and windy weather. The temperature hit 38 degrees and was 33 when the sun hit the horizon at 6 pm.

In an attempt to evaluate the insects temperature adaptations that play a significant role in its establishment potential, life table parameters and the effect of temperature on its fecundity, longevity, host-instar choice, superparasitism and host feeding were studied. Tests were conducted at 20, 25 and 30 ± 0.5 °C with 60 ± 10% RH and a 14L:10D photoperiod. S. petiolatus oviposition period was 21.05 ± 2.54 days at 30 °C but as short as 2.25 ± 0.23 days at 20 °C. Fecundity had a maximum value (173.3 ± 27.09) at 30 °C followed by 143.57 ± 22.67 and 5.13 ± 0.81 at 25 and 20 °C, respectively while, 28.57% of the females failed to oviposit at 20 °C. Female longevity averaged between 25.20 and 20.57 days at 30 and 25 °C, respectively but dropped to just 5.77 days at 20 °C.

  • Wyoming Residents Grow Grapes for Wines, Jellies
    UW Cooperative Extension Service April 2010 Page 3 Wyoming residents grow grapes for wines, jellies By Sandra Frost Bucking horses, coal mines, gas wells, and high, cold desert are images that come to mind first when asked about Wyoming. Grapes and wine are not near the top of the list. Grapes are successfully grown in Wyoming, though, at both the homeowner and commercial scales. Grape varieties may be suitable for juice, jams, and jellies, table grapes, or wine production. Grape variety research was done at the University of Wyoming Sheridan Research and Extension Center (SREC) over several years (www. uwyo.edu/uwexpstn/Sheridan.asp). Colorado State University bhas also conducted grape variety trials under conditions similar to Wyoming and makes variety recommendations (www.coopext. colostate.edu/TRA/PLANTS/fruit.shtml).

Common Name Sweetpotato leaf miner, morning glory leafminer Scientific Name Bedellia somnulentella; previously known as Bedellia ipomoeae. Distribution Worldwide. Asia, Africa, North America, Europe, Oceania. It is present in Australia, Fiji1, New Zealand, and Papua New Guinea. Hosts Sweet potato, kangkong (Ipomoea aquatica), and bindweeds (Calstegia and Convolvulus species). Symptoms & Life Cycle The damage is done by the larvae. Mines are at first serpentine (snake-like), and filled with frass; they become yellow-brown and later grow in width, forming blotches (Photo 1). At this stage, the larvae protrude from the blotch to defaecate. Later still, holes are produced in the leaves as the blotches are destroyed. The eggs are laid on the leaves, usually on the underside near the midrib, veins or base of the leaf blade. The larvae are yellowish with pink spots along the back, developing into red rounded projections on all segments. When mature, the larvae are 5.5 mm long. They exit the mines and make a network of silk threads on the underside of the leaf. When not feeding, they move around inside the threads, above the leaf surface. Frass often catches in the web of threads. The larvae pupate there. Adults are greyish brown, 3.5-4 mm long, with a tuft of light yellow to brown hairs on the head, and wingspan of 8-10 mm (Photos 2&3).
