Hellula Undalis (Lepidoptera: Pyralidae)—A Possible Control Agent?
Biological Control 26 (2003) 202–208 www.elsevier.com/locate/ybcon First detection of a microsporidium in the crucifer pest Hellula undalis (Lepidoptera: Pyralidae)—a possible control agent?

Because H. undalis is difficult to control by chemical insecticides and microbiological control techniques have not been established, we investigated the biology, the pathogenicity and transmission of this pathogen found in H. undalis. An average of 16% of larvae obtained from crucifer fields in Nueva–Ecija displayed microsporidian infections and 75% of infected H. undalis died during larval development. Histopathological studies revealed that the infection is initiated in the midgut and then spreads to all organs. The microsporidium has two different sporulation sequences: a disporoblastic development pro- ducing binucleate free mature spores and an octosporoblastic development forming eight uninucleate spores. These two discrete life cycles imply its taxonomic assignment to the genus Vairimorpha. The size of the binucleate, diplokaryotic spores as measured on Giemsa-stained smears was 3:56 Æ 0:29lm in length and 2:18 Æ 0:21lm in width, whereas the uninucleate octospores measured 2:44 Æ 0:20 Â 1:64 Æ 0:14lm. -

Abstract The cabbage looper moth (CLM), Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) is an agricultural pest that has developed resistance to many frequently used insecticides, so alternative methods are required to reduce greenhouse CLM populations. Host plant volatile organic chemicals (VOCs) are used by female CLMs as cues for host location and oviposition. I hypothesized that changes in host plant VOC production, through genetic modification, could alter host location behaviour by CLMs. These changes in VOCs have potential to give rise to highly attractive transgenic trap crops. -

In Partnership with CATERPILLAR PESTS OF
In partnership with CATERPILLAR PESTS OF BRASSICA CROPS – 21st May 2019 Summaries of sightings of diamond-back moth and silver Y moth in several northern European countries in 2019 can be found here: https://warwick.ac.uk/fac/sci/lifesci/wcc/research/pests/plutella/sightings2019/. These are moths captured or seen and reported on 'biodiversity monitoring' websites. The summaries of ‘citizen science’ moth sightings in the UK and on the continent will be supplemented by on- farm monitoring of diamond-back moth by several members of the Brassica Growers Association. Large numbers of diamond-back moths arrived in the UK on Friday 17th May https://warwick.ac.uk/fac/sci/lifesci/wcc/research/pests/plutella/sightings2019/. The moths were first seen along the east coast of England but may have moved since then. This seems to have been the only ‘pulse’ of moths so far as lower numbers have been seen since then. If they arrive in brassicas then it is likely that the female diamond-back moths will lay eggs quite rapidly. You can get some idea of how long the eggs might take to hatch from the table on this web page https://warwick.ac.uk/fac/sci/lifesci/wcc/research/pests/plutella/.

INTRODUCTION The fauna of noctuoid moths (the families Erebidae and Noctuidae) of Kazakhstan is still poorly studied. Only the fauna of West Kazakhstan has been studied satisfactorily (Gorbunov 2011). On the faunas of other parts of the country, only fragmentary data are published (Lederer, 1853; 1855; Aibasov & Zhdanko 1982; Hacker & Peks 1990; Lehmann et al. 1998; Benedek & Bálint 2009; 2013; Korb 2013). In contrast to the West Kazakhstan, the fauna of noctuid moths of East Kazakhstan was studied inadequately. -

Crucifer Insect Pest Problems: Trends, Issues and Management Strategies
Crucifer insect pest problems: trends, issues and management strategies G.S. Lim1, A. Sivapragasam2 and W.H. Loke2 1IIBC Station Malaysia, P.O. Box 210, 43409 UPM Serdang 2Strategic, Environment and Natural Resources Center, MARDI, P.O. Box 12301, 50774, Kuala Lumpur Abstract Crucifer vegetables are important cultivated crops and are widely grown in many parts of the world, including the highlands in most tropical countries. They are frequently attacked by a number of important insect pests. Some have been a problem for a long time while others have become important only recently. For many, trends are apparent pertaining to their changing status, including other aspects and strategies associated with efforts to counter them. In some cases, they are also closely associated with other agricultural developments and agronomic practices which are driven by commercial interests in vegetable production. Among the major trends recognised are: (1) A number of pests persisting to be important (e.g., Plutella xylostella or diamondback moth (DBM), Pieris rapae, Hellula undalis), (2) Negative impacts of pesticides continuing to be of major concern where DBM remains a serious problem, (3) Some pests becoming more important, either independently of DBM suppression (e.g., leafminer and Spodoptera exigua) or as a consequence of effective DBM control (e.g., aphid and Crocidolomia binotalis), (4) DBM becoming increasingly resistant to Bacillus thuringiensis, and (5) New cultivation practices emerging, such as rain shelter and hydroponic systems. All these have generated new concerns, additional issues and challenges, and have demanded a review of crucifer cultivation and the associated pest problems, including their management practices and approach. -

Stillingfleet Nurseries to Enable the Best of the Catches to Be Shown to the Visitors on Sunday 28 June
Moth trapping at Stillingfleet Lodge Nurseries (SE 589409) from June 2012 Onwards Following a request from Mrs Vanessa Cook for representatives of Butterfly Conservation, Yorkshire Branch to attend a “Conservation Day” in the grounds of Stillingfleet Lodge it was agreed to install moth traps within the grounds and to display the catches to the visiting public at the event. As with much of the early summer in 2012 the weather was not very conducive to flying insects, although a reasonable number of specimens were caught and retained in small see- through containers to enable them to be viewed by the visitors. In spite of the damp conditions a good number of visitors did attend to support the stall set up by Butterfly Conservation, alongside several other attendee conservation groups. The following reports are written by David Baker who was accompanied on all the visits, unless noted otherwise, by David laughlin. The word “trap” alarms some people who associate the word with killing etc. However, no moths were harmed in the exercise and all were released after counting and, in this instance, displaying to other interested parties during the afternoon. At the end of the day we agreed to carry out further trapping later on in the year and, perhaps in following years, to try to assess the species of moths flying in the area of the Lodge and the following lists show the results of further trapping at the site. The three 2012 sessions, separated by several weeks, showed a great variety of moths with repeat species being very few and a total of 94 species were recorded. -

Cabbage Moth Mamestra Brassicae
Michigan State University’s invasive species factsheets Cabbage moth Mamestra brassicae The cabbage moth is a highly polyphagous defoliator, but particularly damaging to cabbage in Europe and Asia. Larval feeding and frass accumulation can lower the commercial value of infested crops. Its introduction to Michigan may pose a concern in particular to vegetable industries, but its infestation may extend to fruit, floriculture, ornamental and other crops. Michigan risk maps for exotic plant pests. Systematic position Insecta > Lepidoptera > Noctuidae > Mamestra brassicae (Linnaeus) Global distribution The insect’s range extends throughout the Palearctic region (Europe, Asia north of the Himalayas and Africa north of the Sahara). Quarantine status This insect is not known to be introduced into North Adult. (Photo: S. van der Molen) America. Plant hosts The cabbage moth is highly polyphagous, known to feed on more than 70 plant species from 22 families. Caterpillars prefer to feed on cruciferous plants, especially cabbage and related Brassica spp. (Brussels sprout, cauliflower, turnip). Other hosts include apple, beetroot, onion, potato, rhubarb and tomato. In Britain, they are an occasional pest of carnations and chrysanthemums grown in greenhouses (Carter 1984). Biology Female moths lay clusters of 20 to 100 eggs on the underside of host plant leaves. Larvae feed on leaves at night and hide at the plant’s base during daytime. Mature larvae burrow into the ground 5-10 cm deep and pupate in a fragile cocoon. They overwinter as pupae. Adults can be Larvae on cauliflower (Photo: BASF) seen from May to October. The moths fly at night and are attracted to light and nectar-rich flowers.
