IPM NEWS --- international IPM news and programs

I. IPM NEWS / APPLICATIONS international IPM news and programs Pheromones to Attract Parasitoids Research under way in the U.K. aims to increase biological control activity of Sitobion avenae (English gain aphid) through baiting fields with pheromones that attract this pest's parasitoids. According to the involved scientists, R. Glinwood and W. Powell at the IARC-Rothamsted research complex, female aphid parasitoids (Braconidae: Aphidiinae) are attracted to aphid sex pheromones, which then help locate the host species. Early results indicate that the attracted parasitoids have the potential to help limit aphid populations, but are most effective during the initial stages of increased aphid presence.

This fact was born out in experimentation where parasitization activity by either Aphidius rhopalosiphi or Praon volucre increased significantly and earlier in pheromone-baited plots compared with untreated control plots.

To date Glinwood and Powell conclude that:

The major parasitoids ofS. avenaeare attracted to aphid sex pheromones; Attracted parasitoids will attack aphids present in the vicinity of pheromone lures; and, Parasitoid behavior can be manipulated on a field scale, providing potential to devise aphid control strategies involving the use of aphid sex pheromones.

Danish Flour Mills Turn to IPM To help develop pest management alternatives for industrial flour mills in Denmark that have been impacted by that nation's total ban on the use of methyl bromide (MBr) since 1 January 1998, the Danish Environmental Protection Agency has launched a project to introduce IPM strategies in three flour mills. Danish flour mills have relied in the past on pest control strategies that, like many mills in other countries, included fumigation with MBr. In Denmark, Mbr was used once or twice a year to prevent infestation problems, primarily with Ephestia kuehniella (Mediterranean flour moth) and Tribolium species (flour beetles).

The goal of the project, being conducted by the mills and two commercial pest control operators under the supervision of the Danish Pest Infestation Laboratory, is to design individual IPM strategies for each mill, and to then initiate implementation. According to project leader, P.S. Nielsen, various IPM strategies used in mills worldwide often rely on Mbr, and there are very few documented investigations of IPM in food processing factories available in literature. For that reason alone, Nielsen believes the project to introduce IPM is considered to be very valuable and could pave the way for the use of biological control in Danish flour mills, and possibly elsewhere.

A report (in English) will be available in February 1999 and, along with other information, can be obtained from: P.S. Nielsen, Danish Pest Infestation Laboratory, Skovbrynet 14, DK-2800 Lyngby, DENMARK E-mail: P.S.Nielsen@SSL.DK Fax: 45-459-31155 Phone: 45-458-78055

IPM MEDLEY --- publications and other IPM information resources

II. IPM MEDLEY general matters, publications of interest, and other resources for IPM information Rats, Rats, Rats: A Roundup In Cambodia: Investigation by staff of the Cambodia-IRRI-Australia Project (CIAP) recorded that 31 percent of wet-season rice farmers and 45 percent of dry-season farmers in Cambodia reported rat problems in their fields. Writing in a recent issue of the CIAP BULLETIN, scientist G.C. Jahn noted that rats can eat all parts of the rice plant at any growth stage, throughout the year.

However, at certain times rats become more prevalent than usual, triggering need for control measures. Where cost-effective, plastic barriers can be placed around rice fields, with holes every 5-10 m (16-32 ft) in the barrier, leading to traps inside the field. When rat populations decrease, anticoagulant and subchronic poison baits can be used, if available; acute poison (e.g., zinc phosphide) baits are recommended when rat populations are high. FMI: G.C.

In the U.S. (Hawaii):

The U.S. National Wildlife Research Center (NWRC) is sponsoring IPM strategies to reduce rodent damage to crops and rangeland in the U.S. state of Hawaii. The research revolves around developing a practical, cost-effective method for applying rodenticides to reduce rat populations. Rats introduced to Hawaii in recent centuries have contributed to the region's ecological devastation through predation and competition with native fauna and flora.

According to NWRC, use of rodenticides is the most cost-effective method of reducing rodent populations. However, current methods of rodenticide application in native Hawaiian habitats require bait stations and thus are labor intensive and impractical for use over large areas.

Research evaluating both the minimum exposure time and rodenticide dosage has been completed. Alternative methods of bait distribution are currently under investigation. FMI: NWRC, 1201 Oakridge Dr., Fort Collins, CO 80525, USA Fax: 1-970-223-0776 Phone: 1-970-223-0776

In Vietnam:

A sharp decrease in rats' natural predators cats and snakes was blamed for a meteoric build-up in the country-wide rat population leading to an all-out campaign to eradicate the rodents devastating Vietnam's crops that, said a recent report, resulted in the killing of more than 47.2 million rats during the first five months of 1998.

An official source estimated that nearly 230,000 ha (568,100 a) of rice and more than 40,000 ha (98,800 a) of vegetables had been damaged by rats since January this year. The officially sanctioned campaign was country-wide and involved mobilization of millions of students and farmers to aid the anti-pest effort, including raising more cats.

MANAGING AN INSECT PEST Periodically, pest management literature spawns short, factfilled, attractively designed documents that succinctly define a problem and then offer useful pest management information. The 1997-98 leaflet, MANAGING THE JAPANESE BEETLE: A HOMEOWNERS'S HANDBOOK, produced through the U.S. Department of Agriculture's Animal and Plant Health Inspection Service, is just such a model document. Co-authors entomologist P.C. Kingsley (Otis Plant Protection Center) and K. Cahow include full color plates of the target pest, Popillia japonica Newman, and then lay out key alternatives for its management, all in the context of IPM. The clear 16-page work is Program Aid no. 1599. FMI: P.C.

EQUIPMENT & MATERIALS NEW ANTI-DRIFT NOZZLE DESIGN To reduce spray drift, one of the more intractable problems of liquid pesticide application, spray nozzle manufacturers have worked to develop equipment that would produce less drift. One of the latest anti-drift designs is the TeeJet Air Induction (AI) Nozzle that incorporates a venturi to draw air into the spray liquid flowing through the nozzle resulting in larger, air-filled droplets that are less prone to drift. The air bubble-filled droplets are also less dense and thus tend to disintegrate more readily on impact creating a splatter effect that theoretically provides increased coverage inside a target canopy. The AI nozzle's removable, polymer pre-orifice creates more droplets of more uniform size, even at higher operating pressures. AI nozzles are designed to fit into standard nozzle body and cap assemblies.

IPM RESEARCH/TECHNICAL PAPERS --- categories and topics related to IPM

III. RESEARCH/TECHNICAL PAPERS research/technical topics related to IPM. NEW: IPMnet NEWS, in support of global IPM and in response to reader feedback, herewith launches a service of providing first author mail addresses (for those articles marked with "##" at the end of the citation) to facilitate contacts, requests for reprints, or other interaction. While not every paper is included initially, the NEWS aims to eventually mark (##) every paper mentioned. Interested parties can request first author address information via e-mail from: IPMnetNUZ@bcc.orst.edu or by mail, phone, or fax (see box at end of this issue). As before, IPMnet also can provide mailing addresses for any of the listed journals.

FEATURED PAPER Considerable reporting has described consumer and public reactions to genetically-modified crops, but the all-important attitude of farmers towards the new technology remains less clear. To shed more light on the topic, two U.S. researchers summarized the results of a survey involving 800 farmers in, "Management of European Corn Borer (Lepidoptera: Crambidae) and Corn Rootworms (Coleoptera: Chrysomelidae) with Transgenic Corn: A Survey of Farmer Perceptions," published in AMERICAN ENTOMOLOGIST. Authors C.D. Pilcher and M.E. Rice found that the surveyed group of U.S. farmers showed a clear interest in corn enhanced with Bacillus thuringiensis and that a substantial majority felt the main advantage of B.t. corn was reduced exposure of farm workers to insecticide. These farmers also applauded the potential for an increase in yields and a decrease of insecticide released into the environment. excerpted from: AMER. ENTOM., 44(1), 36-44, Spring 1998. ##
