IPM OF MOLE CRICKETS WITH A COMBINATION OF NATURAL ENEMIES Howard Frank UF/IFAS Mole Cricket Research Program Entomology & Nematology Department University of Florida

Slide 2

why doesn\'t the northern mole cricket waste turf all through the eastern USA?

Slide 3

in any event to a limited extent since it is assaulted by a master local wasp, Larra analis and a pro local nematode, Steinernema neocurtillae . UF/Choate

Slide 4

So, turf directors in the eastern USA don\'t need to stress over the northern mole cricket - which is local to the USA. Yet, in Brazil, where the northern mole cricket is NOT local, it has been asserted to bring about harm.

Slide 5

Native bugs may have authority normal adversaries, (for example, wasps and nematodes) that control them … free! However, when creepy crawlies touch base from abroad, they may get to be bugs in light of the fact that their local common foes were deserted in their country.

Slide 6

"IPM procedures by and large depend first upon organic barriers before artificially modifying nature." a portion of President Carter\'s 1979 Environmental Message

Slide 7

harm by vermin (South American) mole crickets to a Florida fairway J.P. Parkman/UF

Slide 8

Ever since the brownish, southern, and shortwinged mole crickets landed from South America (100 years prior), turf directors have depended basically on concoction pesticides against them So, what was the deal?

Slide 9

What happened to the lesson just clarified – that regular adversaries can control them? What happened to President Carter\'s message that "IPM methodologies by and large depend first upon organic safeguards before artificially adjusting the earth."

Slide 10

The expert characteristic adversaries were not here in Florida – they were in South America – and they required examination. The undeniable answer was to bring them from South America and exploration them. They may give free control of the vermin mole crickets.

Slide 11

Four biocontrol operators were conveyed to Florida from South America by the UF/IFAS Mole Cricket Research Program in the 1980s 1. a wasp: Larra bicolor 2. a fly: Ormia depleta 3. a creepy crawly: Pheropsophus aequinoctialis 4. a nematode: Steinernema scapterisci

Slide 12

The undertaking from that point forward has been to : test whether they are ok for discharge (and, on the off chance that they are): 2. spread them all through Florida 3. figure out how to improve their populaces locally where their administrations are required Here\'s the place we are currently:

Slide 13

imported wasp Larra bicolor

Slide 14

from Bolivia 1988 the wasp Larra bicolor Present in any event the areas checked, and spreading in northern provinces from Puerto Rico1981

Slide 15

the wasp Larra bicolor 1. was presented from Bolivia in the 1980s 2. was discharged in Alachua County 3. has spread to neighboring areas – in any event to Putnam, Clay, and Levy - possibly more

Slide 16

Spermacoce verticillata (a wildflower) gives nectar to the grown-up wasps Spermacoce verticillata (a wildflower) gives nectar to the grown-up wasps – it and different wildflowers maybe can be utilized to upgrade nearby populaces of the wasp – like butterfly planting UF/Choate

Slide 17

imported fly Ormia depleta UF/Castner

Slide 19

the fly Ormia depleta 1. was presented from Brazil in the 1980s 2. was discharged in Alachua County – and numerous different regions 3. Presently involves 38 areas – from Alachua southward – is not spreading northward

Slide 20

hatchling of imported scarab Pheropsophus aequinoctialis with mole cricket eggs UF/Castner

Slide 21

the bug Pheropsophus aequinoctialis 1. was gotten to isolate Gainesville from Uruguay and Brazil in the 1980s, then from Bolivia in 1993 2. has not yet been discharged – some entomology graduate understudies have chipped away at it – yet we should be absolutely certain of its eating routine before a discharge grant can be issued

Slide 22

dead mole cricket with rose Steinernema scapterisci nematodes UF/Nguyen

Slide 23

the nematode Steinernema scapterisci 1. was presented from Uruguay in 1985 2. was discharged in Alachua County in 1985, and spread in that region 3. was mass-created by industry on a fake eating regimen, and sold as a biopesticide 4. exploratory discharges and business deals spread it to numerous different areas

Slide 24

The nematode contrasts from the wasp and the fly in two ways: (1) it needs just mole crickets to survive (the grown-up wasp and grown-up fly need vitality from nectar or honeydew) (2) it can be mass-created and sold as a biopesticide (this is going on) This doesn\'t mean the nematode is a superior biocontrol operator, simply that it can be taken care of like a pesticide

Slide 25

The work has brought about foundation of populaces of the wasp and the nematode in the Gainesville range. Those two biocontrol specialists together have diminished irritation mole cricket numbers by around 95% in the Gainesville range subsequent to the 1980s

Slide 26

southern mole cricket, Gainesville biocontrol period

Slide 27

My vision is of the nearness of good populaces of no less than two types of these biocontrol operators all over in Florida to give statewide biocontrol At that point, overwhelming mole cricket harm will be a relic of days gone by

Slide 28

Pesticides (either concoction or organic) will be utilized against mole crickets just on fairway tees and greens. Individuals will plant chose wildflowers to support nearby populaces of the wasp and the fly. What\'s more, control expenses will be FAR not exactly at present.

Slide 29

It is imperative to recollect that every one of the four biocontrol operators are relied upon to add to perpetual biocontrol of vermin mole crickets And they don\'t hurt non-target life forms – not even the northern mole cricket

Slide 30

About 80% of the backing for the UF/IFAS Mole Cricket Research Program originated from UF/IFAS reserves reserved in 1978-1991 by the Florida lawmaking body for this reason, around 10% from the Federal government, and 10% (preceding 1992) from the turf business. The examination employment is a long way from wrapped up. It could be speeded if the exploration were better financed by the turf business.
