Administration of Pest Mole Crickets in Florida and Puerto Rico with a Nematode and Parasitic Wasp N. C. Leppla, J. H. Blunt and M. B. Adjei

Slide 2

Scapteriscus didactylus, the "West Indian mole cricket" or "changa," most likely touched base in the West Indies by flying from South America several years prior

Slide 3

Scapteriscus abbreviatus , the "short-winged mole cricket," happens in Puerto Rico and a couple of different islands, and presumably landed in boat ballast~ this species can\'t fly and is just a minor issue

Slide 7

Mole cricket harm and substance pesticides for control cost an expected 100 million dollars in the Southeastern US every year Chemicals are excessively costly for use on field land Mole crickets bounce back in most treated zones Concern about non-target impacts of chemicals Chemical Control www.pesticidereform.org

Slide 10

Steinernematid Life Cycle entrance free-living nematodes leave the body and are incidentally free-living adolescents create in the host body produce eggs sexual development

Slide 11

Flask containing nematodes on eating routine drenched wipe

Slide 12

Application of nematodes to pasture land

Slide 13

Mole Cricket State Program Objective : To lead research/showing projects that will generally convey the entomopathogenic nematode, Steinernema scapterisci , in Florida; decide its establishment, rate of spread and effect on Scapteriscus spp. mole crickets, and backing its commercialization

Slide 14

Nematac S 80 billion nematodes 32 districts Education & preparing Nematode diagnostics Nematode overview Refined techniques Establish & Spread Nematode applications

Slide 15

Mole Cricket Nematode in Florida 6 months-80% mole crickets contaminated 1 year-tainted mole crickets spread nematodes over the field 3 years-85% decrease in mole crickets 40-95% recuperation of bahiagrass 20-35% contaminated mole crickets

Slide 16

Biological Control of Mole Crickets in Florida by the Nematode

Slide 17

Mole Cricket Nematode Project In Puerto Rico Apply Nematac S in proper natural surroundings Survey for entomopathogenic nematodes Adapt discharge and assessment strategies Demonstrate foundation and spread Determine the effect on nuisance mole crickets

Slide 24

Biological Control of Mole Crickets in Puerto Rico by the Nematode Scapteriscus didactylus , was caught at the green and natural patio nursery Scapteriscus abbreviatus was likewise found at the natural greenery enclosure Mole crickets caught at the fairway contained Steinernema scapterisci Steinernema scapterisci got to be built up at the green and killed S. didactylus Mole crickets from the natural patio nursery were not contaminated

Larra bicolor on Spermacoce verticillata Lyle Buss-UF, IFAS

Slide 27

Biological Control of Mole Crickets in Florida & Puerto Rico by the Wasp Parasitism of Scapteriscus vicinus 24% close Gainesville, Florida Wasp in 22 Florida districts by characteristic spread and discharges Larra bicolor bolsters at nectaries of 4 plants in addition to Spermacoce verticillata Spermacoce verticillata plots gave close mole cricket infestations Cooperators look for wasps encouraging on the blossoms Wasp may work additively with the nematode

Slide 28

Management of Pest Mole Crickets in Florida and Puerto Rico Established the nematode and wasp Determined that they are compelling Provided sparing mole cricket control We have demonstrated that organic control offers long haul, financially savvy mole cricket administration
