Interrelation of mating, flight, and fecundity in navel orangeworm females Abstract The an vel orangeworm, Amyelois transitella (Walker) (Lepidoptera: Pyralidae, Phycitini), is an economically important pest of nut crops in California, USA. Improved management will require better understanding of insect dispersal, particularly relative to when mating occurs. A previous study demonstrated a more robust laboratory flight capacity compared to other orchard moth pests, but it was unclear how mating affects dispersal, and how dispersal affects fecundity. In this study, 1‐ and 2‐day‐old females were allowed to fly overnight on a flight mill either before or after mating, respectively, and were then allowed to oviposit.

Similar to dry Life Histories grains, these commodities are typically maintained and Behavior at such low moisture levels that preserving quality by minimizing insect damage can be a significant chal- lenge. Stored commodities may become infested at the processing plant or warehouse, in transit, at the store, or at home. Many arthropod pests of stored commodities are relatively abundant outdoors, but natural host plants before preadaptation to stored products remain unknown. Capable of long flight, they migrate into unprotected warehouses. Adults (larvae) crawl through seams and folds or chew into sealed packages and multiply, diminishing product quality and quantity. Infestations may spread within a manufacturing facility through electrical conduit Figure 1. Adult of the cigarette beetle, Lasioderma serricorne and control panels.

  • Moth Species Captured with the Sex Pheromone of Stenoma Catenifer (Lepidoptera: Elachistidae) in Avocado Plantations of Southern Mexico
    Castillo et al.: Moth Species Captured with Stenoma catenifer Sex Pheromone 1111 MOTH SPECIES CAPTURED WITH THE SEX PHEROMONE OF STENOMA CATENIFER (LEPIDOPTERA: ELACHISTIDAE) IN AVOCADO PLANTATIONS OF SOUTHERN MEXICO ALFREDO CASTILLO*, LEOPOLDO CRUZ-LOPEZ AND JAIME GÓMEZ El Colegio de la Frontera Sur (ECOSUR), Carretera Antiguo Aeropuerto km 2.5. Tapachula, 30700 Chiapas, Mexico *Corresponding author; E-mail: [email protected] ABSTRACT Moth species trapped using the sex pheromone of Stenoma catenifer (LaSalle) as a lure, were registered at 2 commercial avocado orchards (one consisting of “Hass” and other of “Criollo”) and in wild “Criollo” avocado trees in southern Mexico. Traps were maintained for 1 mo in two seasons (dry and wet) on avocado trees under these 3 production conditions, changing the baits each season. Weekly observations registered no moths in the traps placed in the commercial “Hass” avocado orchard, in contrast to the other 2 sites, where Stenoma cateni- fer and Antaeotricha nictitans males were captured. Stenoma catenifer adults were always observed at the commercial “Criollo” orchard and wild “Criollo” avocado trees during the dry season (fructification period), but never in the wet season (non fruiting period). Under wild conditions A. nictitans was captured during both dry and wet seasons; however, it was never captured during the dry season at the commercial “Criollo” orchard. Populations of both moth species were similar -S. catenifer: 0.3 (wild trees) to 0.7 (orchard); and A. nicti- tans: 0.6 (wild trees) moth/trap/wk- during the dry season, and no differences were observed per species at each locality. The total number of captures per site during the fruiting season decreased significantly -0.9 (1st wk) to 0.2(4th wk) moth/trap/wk- during the observation period.

  • Insect Pests of Stored Foods
    Insect pests of stored foods Jeffrey Hahn, Professor and Assistant Extension Entomologist, University of Minnesota Laura Jesse, Extension Entomologist, Iowa State University Phil Pellitteri, Distinguished Faculty Associate, Department of Entomology, University of Wisconsin Insects infesting stored foods are one of the most common household insect problems. The many different kinds of insects that infest stored dried foods are often referred to as "pantry pests." Significance Pantry pests contaminate more food than they consume, and most people find the contaminated products unfit for consumption. Pantry pests are often discovered when they leave infested foods to crawl or fly about the house. They often accumulate in pots, pans or dishes or on window sills. Fortunately, they do not bite or sting people or pets nor do they feed on or damage the house structure or contents. What do they eat? Nearly all dried food products are susceptible to insect infestation, including cereal products (flour, cake mix, cornmeal, rice, spaghetti, crackers, and cookies); seeds such as dried beans and popcorn; nuts; chocolate; raisins and other dried fruits; spices; powdered milk; tea; and cured meats. Non-food items that may be infested include birdseed, dry pet food, ornamental seed and dried plant displays, ornamental corn, dried flowers, garden seeds, potpourri, and rodent baits. Stored food insects are most likely to infest products that have been opened but are also capable of penetrating unopened paper, thin cardboard, and plastic, foil, or cellophane-wrapped packages. They may chew their way into packages or crawl in through folds and seams. Insects within an infested package begin multiplying and can spread to other stored foods not only in the same area but in other rooms in a home.

  • Species on the Menu of a Generalist
    Molecular Ecology (2009) 18, 2532–2542 doi: 10.1111/j.1365-294X.2009.04184.x SpeciesBlackwell Publishing Ltd on the menu of a generalist predator, the eastern red bat (Lasiurus borealis): using a molecular approach to detect arthropod prey ELIZABETH L. CLARE,* ERIN E. FRASER,† HEATHER E. BRAID*, M. BROCK FENTON† and PAUL D. N. HEBERT* *Department of Integrative Biology, University of Guelph, Guelph, ON, Canada N1G2W1, †Department of Biology, University of Western Ontario, London, ON, Canada N6A 5B7 Abstract One of the most difficult interactions to observe in nature is the relationship between a predator and its prey. When direct observations are impossible, we rely on morphological classification of prey remains, although this is particularly challenging among generalist predators whose faeces contain mixed and degraded prey fragments. In this investigation, we used a poly- merase chain reaction and sequence-based technique to identify prey fragments in the guano of the generalist insectivore, the eastern red bat (Lasiurus borealis), and evaluate several hypotheses about prey selection and prey defences. The interaction between bats and insects is of significant evolutionary interest because of the adaptive nature of insect hearing against echolocation. However, measuring the successes of predator tactics or particular prey defences is limited because we cannot normally identify these digested prey fragments beyond order or family. Using a molecular approach, we recovered sequences from 89% of the fragments tested, and through comparison to a reference database of sequences, we were able to identify 127 different species of prey. Our results indicate that despite the robust jaws of L. borealis, most prey taxa were softer-bodied Lepidoptera.

  • Light-Trap Catch of Harmful Microlepidoptera Species in Connection with Polarized Moonlight and Collecting Distance
    Journal of Advanced Laboratory Research in Biology E-ISSN: 0976-7614 Volume 4, Issue 4, October 2013 PP 118-127 https://e-journal.sospublication.co.in Review Article Light-trap Catch of Harmful Microlepidoptera Species in Connection with Polarized Moonlight and Collecting Distance Nowinszky L.*, and Puskás J. *University of West Hungary, H-9701-Szombathely, Károlyi Gáspár Square 4, Hungary, Europe. Abstract: The paper deals with light-trap catch of 25 Microlepidoptera species depending on the polarized moonlight and collecting distance. The catching data were chosen from the 27 stations of the Hungarian National Light-trap Network and from the years between 1959 and 1961. Relative catch values were calculated from the catching data per stations and swarming. They are ranged and averaged in the phase angle divisions. The catching peak of ten species is in First Quarter, another ten species have the peak in the First Quarter and Last one, and only in two cases, the peak is in Last Quarter. Then there is the maximum ratio of polarized moonlight. Catching peak of only three species is in connection with the collecting distance when is the greatest of collection distance.

  • Stored Grain Insect Reference March 2015
    Abstract Five primary pests cause most of the insect damage to grain in storage and shipment. These are the granary weevil, the rice weevil, the maize weevil, the lessor grain borer or Australian wheat weevil, and the Angoumois grain moth. Other insect species or groups of species described in this handbook can cause great damage to grain if storage conditions are unusually favorable for their increase. Yet, if grain in the unbroken kernel remains unaffected by the five primary pests, it is not likely that any other insect will damage it appreciably in commercial storage or shipment, except possibly the khapra beetle. The secondary pests are mostly surface feeders in both the adult and larval stages. Some of them may eat into kernels of grain and lie hidden there, but most of them feed on grain dust or broken surfaces of kernels exposed by either mechanical injury to the grain in handling or by feeding of the five primary grain pests with which they are usually associated.Therefore the secondary pests can be largely removed by grain-cleaning operations. Except for the lessor grain borer, the larvae or grubs of the primary insect pests are not ordinarily capable of a free existence outside the kernel. they live entirely within the kernel, where they feed unseen and usually unsuspected. They cannot be removed by ordinary cleaning machinery and must be controlled by other means.
