Pest Profile Photo credit: Jim Kalisch, University of Nebraska Common Name: Mediterranean flour moth Scientific Name: Anagasta kuehniella Order and Family: Lepidoptera: Pyralidae Size and Appearance: The Mediterranean flour moth is a small greyish moth, with long front wings that are rounded at the tips. At rest, the adult will often raise its forelegs, elevating the front of its body. Length (mm) Appearance Egg Average 0.57 mm Eggs are greyish-white and oval shaped. They are laid on the food for larvae and adhere to the material. Larva/Nymph Up to 19 mm Larvae are whitish but can have some light pinkish to yellowish coloring. They have a reddish-brown or yellowish-brown head. Young larvae constantly spin silken tubes to harbor in. Adult 10 – 14 mm The wings are pale grey to a brownish-grey with some darker grey markings that may appear wavy. The wingspan is 18 – 27 mm. Adults are attracted to light. Pupa (if applicable) Pupae are yellowish-brown to reddish-brown. Larvae travel away from the infested food area to pupate. Type of feeder (Chewing, sucking, etc.): The larvae have chewing mouthparts. Adults have siphoning mouthparts but are not known to feed. Host/s: The larvae will feed on a variety of foods. Among the foodstuffs they attack are flour, bran, grains, maize, rice, sorghum, oats, barley, dried fruits, nuts, seeds, and chocolate. The adults do not cause damage. Description of Damage: The Mediterranean flour moth is an external feeder and damage to goods always begins on the outside surface. It is an important pest of flourmills and warehouses. It produces webbing that will make the appearance of grains undesirable, and may clog machinery, forcing temporary shutdowns in mills. In homes, they are most commonly found in flour or cereals, but can be pests of other stored foods. If found, infested food should be disposed of outdoors and storage areas should be cleaned.

Functional Response of Habrobracon Hebetor Say (Hym.: Braconidae) to Mediterranean Flour Moth (Anagasta Kuehniella Zeller), in Response to Pesticides
JOURNAL OF PLANT PROTECTION RESEARCH Vol. 53, No. 4 (2013) DOI: 10.2478/jppr-2013-0059 FUNCTIONAL RESPONSE OF HABROBRACON HEBETOR SAY (HYM.: BRACONIDAE) TO MEDITERRANEAN FLOUR MOTH (ANAGASTA KUEHNIELLA ZELLER), IN RESPONSE TO PESTICIDES Vahid Mahdavi1*, Moosa Saber2 1 Young Researchers Club, Parsabad Moghan Branch, Islamic Azad University, Parsabad, 56918-53356, Iran 2 Department of Plant Protection, College of Agriculture, University of Maragheh, Maragheh, 55181-83111, Iran Received: April 1, 2013 Accepted: October 21, 2013 Abstract: The functional response is a behavioral phenomena defined as the relation between the parasitized host per each parasitoid and host density. This phenomenon can be useful in assessing parasitoid efficiency for the biological control of the host. Parasitoid wasps are most important insects and they play a significant role in the natural control of pests via their parasitism activities. In this study, the effects of diazinon and malathion were evaluated on the functional response of Habrobracon hebetor Say to different densi- ties of last instar larvae of Anagasta kuehniella Zeller. Young adult females (< 24 h old) of the parasitoid were exposed to LC30 values of pesticides. Host densities of 2, 4, 8, 16, 32, and 64 were offered, to treated young females for 24 h in 10 cm Petri dishes. At this point, the parasitism data were recorded. The experiments were conducted in eight replications. The functional response was type Ш in the control and insecticide treatments. Searching efficiency in the control, diazinon and malathion-treated wasps were 0.008±0.002, 0.003±0.002, and 0.004±0.002 h–1, handling times were 1.38±0.1, 7.95±0.91, and 6.4±0.81 h, respectively.

PESTS of STORED PRODUCTS a 'Pest of Stored Products' Can Refer To
PESTS OF STORED PRODUCTS A ‘pest of stored products’ can refer to any organism that infests and damages stored food, books and documents, fabrics, leather, carpets, and any other dried or preserved item that is not used shortly after it is delivered to a location, or moved regularly. Technically, these pests can include microorganisms such as fungi and bacteria, arthropods such as insects and mites, and vertebrates such as rodents and birds. Stored product pests are responsible for the loss of millions of dollars every year in contaminated products, as well as destruction of important documents and heritage artifacts in homes, offices and museums. Many of these pests are brought indoors in items that were infested when purchased. Others originate indoors when susceptible items are stored under poor storage conditions, or when stray individual pests gain access to them. Storage pests often go unnoticed because they infest items that are not regularly used and they may be very small in size. Infestations are noticed when the pests emerge from storage, to disperse or sometimes as a result of crowding or after having exhausted a particular food source, and search for new sources of food and harborage. Unexplained occurrences of minute moths and beetles flying in large numbers near stored items, or crawling over countertops, walls and ceilings, powdery residues below and surrounding stored items, and stale odors in pantries and closets can all indicate a possible storage pest infestation. Infestations in stored whole grains or beans can also be detected when these are soaked in water, and hollowed out seeds rise to the surface, along with the adult stages of the pests, and other debris.

Others may include the Mediterranean flour moth and the meal moth. The larval stage causes the injury. Larvae feed on flour and meal products, dried fruits, nuts, bird food and dried pet foods. As the larva feeds it spins a web leaving behind a silken thread wherever it crawls. Small particles of food often adhere loosely to the thread making it conspicuous. Many times an infestation is noticed when moths are seen flying around the home in the evening. They are attracted to lights and often appear in front of the television screen. Description The Indian meal moth has a wingspan of about 3/4 inch (18-20mm). The outer 2/3 of the wings are bronze to reddish brown, while the inner 1/3 is a Indian meal moth Plodia interpunctella (Hübner) Life grayish white. The larvae (caterpillars) are about 1/2 Cycle inch (12.5mm) long when mature.

The pupa (resting stage) is in a loose silken cocoon spun by the larvae and is a light brown color. Life History A female Indian meal moth can lay from 100 to 300 eggs during her lifetime. Eggs are laid singly, or in groups on the food materials.

Hymenoptera, Braconidae, Habrobracon hebetor, Lepidoptera, Pyralidae, Ephestia kuehniella, biological control, ectoparasitoid, stored products, artifi cial diet, Nicotiana tabacum Abstract. Host diet often infl uences its biological parameters and the success of their parasitoids, both in mass rearing, fi eld research and parasitism in applied biological control programs. Habrobracon hebetor (Say, 1836) (Hymenoptera: Braconidae) is an important biological control agent of the fl our moth Ephestia kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae), which infests tobacco, grain and other products in storage. This study aimed to evaluate the effect of different proportions of tobacco in artifi cial diets on the biological parameters of the host E. kuehniella and its parasitoid H. hebetor. Four classes of Virginia tobacco with dif- ferent sugar and nicotine concentrations were added to fl our diets for moths in different percentages (5, 10 and 15%).The experi- mental design was completely randomized in a 3 × 4 factorial scheme (percentage of dietary tobacco × class of tobacco).

Lepidoptera, Noctuoidea, Erebidae, Spilarctia robusta, phylogenetic analyses, mitogenome, evolution, gene rearrangement Abstract. The complete mitochondrial genome (mitogenome) of Spilarctia robusta (Lepidoptera: Noctuoidea: Erebidae) was se- quenced and analyzed. The circular mitogenome is made up of 15,447 base pairs (bp). It contains a set of 37 genes, with the gene complement and order similar to that of other lepidopterans. The 12 protein coding genes (PCGs) have a typical mitochondrial start codon (ATN codons), whereas cytochrome c oxidase subunit 1 (cox1) gene utilizes unusually the CAG codon as documented for other lepidopteran mitogenomes. Four of the 13 PCGs have incomplete termination codons, the cox1, nad4 and nad6 with a single T, but cox2 has TA. It comprises six major intergenic spacers, with the exception of the A+T-rich region, spanning at least 10 bp in the mitogenome.
