  • False Codling Moth Thaumatotibia Leucotreta
    Stone Fruit Commodity-Based Pest Survey False Codling Moth Thaumatotibia leucotreta Introduction False codling moth (Figure 1) is a significant pest because of its potential economic impact on many crops, including stone fruit, avocado, citrus, corn, cotton, and macadamia. It is not currently known to be present in the United States. Biology Depending on conditions, the false codling moth’s life cycle ranges from 30 to 174 days. It can produce from 2 to 10 generations each year, depending on multiple factors including temperature, food availability and quality, and humidity. To attract males, adult females release pheromones at FIGURE 1. Adult false codling moth (Thaumatotibia leucotreta). Photo courtesy of night. After the adults mate, the female deposits eggs on Pest and Diseases Image Library, Bugwood.org. host plants, either in batches or as single eggs. Later, the hatching larvae burrow into the rind of the host plant. Mature larvae spin cocoons and pupate before they emerge as adults. Symptoms False codling moth can attack stone fruit at any stage. Larvae can even develop in hard green fruit prior to application of control measures. Larvae burrow at the stem end into the fruit and cause damage by feeding around the stone. Damaged fruit can become vulnerable to secondary pests such as fungal organisms and scavengers. Peaches can be damaged by larvae beginning up to 6 weeks before harvest. False codling moth can also attack plants unsuitable for larvae development, such as avocado, causing lesions on fruit tissue and diminishing the marketability of fruit. Because false codling moth is an internal feeder, few symptoms are actually displayed by the larvae.

    Acta zoologica cracoviensia, 46(suppl.– Fossil Insects): 37-50, Kraków, 15 Oct., 2003 Searching for palaeontological evidence of viruses that multiply in Insecta and Acarina Osvaldo LOVISOLO and Oscar RÖSLER Received: 31 March, 2002 Accepted for publication: 17 Oct., 2002 LOVISOLO O., RÖSLER O. 2003. Searching for palaeontological evidence of viruses that multiply in Insecta and Acarina. Acta zoologica cracoviensia, 46(suppl.– Fossil Insects): 37-50. Abstract. Viruses are known to be agents of important diseases of Insecta and Acarina, and many vertebrate and plant viruses have arthropods as propagative vectors. There is fossil evidence of arthropod pathogens for some micro-organisms, but not for viruses. Iso- lated virions would be hard to detect but, in fossil material, it could be easier to find traces of virus infection, mainly virus-induced cellular structures (VICS), easily recognisable by electron microscopy, such as virions encapsulated in protein occlusion bodies, aggregates of membrane-bounded virus particles and crystalline arrays of numerous virus particles. The following main taxa of viruses that multiply in arthropods are discussed both for some of their evolutionary aspects and for the VICS they cause in arthropods: A. dsDNA Poxviridae, Asfarviridae, Baculoviridae, Iridoviridae, Polydnaviridae and Ascoviridae, infecting mainly Lepidoptera, Hymenoptera, Coleoptera, Diptera and Acarina; B. ssDNA Parvoviridae, infecting mainly Diptera and Lepidoptera; C. dsRNA Reoviridae and Bir- naviridae, infecting mainly Diptera, Hymenoptera and Acarina, and plant viruses also multiplying in Hemiptera; D. Amb.-ssRNA Bunyaviridae and Tenuivirus, that multiply in Diptera and Hemiptera (animal viruses) and in Thysanoptera and Hemiptera (plant vi- ruses); E. -ssRNA Rhabdoviridae, multiplying in Diptera and Acarina (vertebrate vi- ruses), and mainly in Hemiptera (plant viruses); F.

Larva of Thaumatotibia leucotreta (T. Grove Taxonomic Position and W. Styn, bugwood.org). Class: Insecta, Order: Lepidoptera, Family: Tortricidae Reason for Inclusion CAPS Target: AHP Prioritized Pest List - 2003 through 2014 Pest Description Eggs: Eggs are flat, oval (0.77 mm long by 0.60 mm wide) shaped discs with a granulated surface. The eggs are white to cream colored when initially laid. They change to a reddish color before the black head capsule of the larvae becomes visible under the chorion prior to hatching (Daiber, 1979a). 1 Larvae: First instar (neonate) larvae approximately 1 to 1.2 mm (< /16 in) in length with dark pinacula giving a spotted appearance, fifth instar larvae are orangey-pink, 1 becoming more pale on sides and yellow in ventral region, 12 to 18 mm (approx. /2 to 11 /16 in) long, with a brown head capsule and prothoracic shield (Fig. 1). [Note this coloration is only present in live specimens.] The last abdominal segment bears an anal comb with two to ten “teeth.” The mean head capsule width for the first through fifth instar larvae has been recorded as: 0.22, 0.37, 0.61, 0.94 and 1.37 mm, respectively (Daiber, 1979b). Diagnostic characters would include the anal comb with two to ten teeth in addition to: L pinaculum on T1 enlarged and extending beneath and beyond (posterad of) the spiracle; spiracle on A8 displaced posterad of SD pinaculum; crochets unevenly triordinal, 36-42; L-group on A9 usually trisetose (all setae usually on same pinaulum) (Brown, 2011).

  • False Codling Moth
    Fact sheet False codling moth What is the False codling moth? The False codling moth (Cryptophlebia leucotreta) is an internal fruit feeding moth that can be found throughout the year in warm climates and has been recorded as feeding on over 50 different plant species. This moth causes economic loss in a range of crops in sub-Saharan Africa. Losses during infestations can be between 20-30%. What does it look like? Adult moths are 15-16 mm (males) and 19-20 mm Citrus Research International, Bugwood.org J.H. Hofmeyr, (female) in length. Forewings have grey, brown, Eggs are oval shaped and almost 1 mm long black and orange-brown markings. A triangular marking on the outer part of the wing with a crescent shaped marking above it distinguishes the False codling moth from other species. Young larvae are yellowish-white with dark spots but bright red or pink when fully grown (15 mm), with a yellow-brown head. Pupae are contained within a tough silken cocoon amongst debris or in the soil. Female moths lay 100-400 eggs (oval, flattened and almost 1 mm in length) singly on the fruits at night. J.H. Hofmeyr, Citrus Research International, Bugwood.org J.H. Hofmeyr, What can it be confused with? False codling moth pupae False codling moth can look similar to other moths but can be distinguished by the triangular marking near the edges of the wings. What should I look for? The young larvae mine fruit just beneath the surface, or bore into the skin causing premature ripening of the fruit.
