Natural pest control ... using bugs Shimon Steinberg

but lover myself not from childhood by

the way but rather late when I bachelor

the major use ology Tel Aviv University

I kind of fell in love with butts and

then within Salah G I took the course of

the discipline of entomology the science

of incense then I thought myself how can

I be practical or or helped in the size

of entomology then I moved to the world

of plant protection plant protection

from insects for bedbugs and then within

plant protection I came into the

discipline of biological pest control

which we actually define as the use of

living organisms to reduce populations

of noxious plant pests so it’s a whole

discipline in Atlanta textured the a big

introduction of chemicals and biological

pest control by the way or these good

bugs that we are talking about they

existed the world for thousands of

thousands of years for a long long time

but only they happen in last hundred and

twenty years people started or people

view more and more how to explore to how

to use this biological controls

phenomenon or in fact natural control

phenomena to their own needs because

phenomena you can see it in your

backyard just take a magnifying glass to

see what they have here

that’s a magnifier times ten yeah times

ten just open it you just twist leaves

and you see a whole new world of by in

hood

or little spiders of 1 millimeter 1 and

1/2 2 meter meter mere millimeters long

and you can distinguish between the good

ones and the bad ones so this phenomenon

of of mental control exists literally

everywhere here in front of this

building got you just have a look at the

plans so is everywhere and we need to

know how to exploit it

well let us know just hand by hand and

browse through just a few examples

what is a pest what damage it actually

flips on the plant and what is the

natural enemy define a logical control

agent or the good bug that we are

talking about in general I’m going to

talk about insects and spiders or bites

let us call them insensitive select

organisms and spider or mice the eight

left organisms let’s have a look at that

here is the best devastating test a

spider bite because it has a lot of

weapon like a spider you see the mother

in between and two daughters probably on

the left and right and a single egg on

the right hand side and then you see

what type of damage it can inflict on

your right hand side you can see

cucumber leaves and in the middle

cotton leaf and on the left and tomato

leaf with these little stippling they

can literally turn from green to white

because of the sucky Piercy about parts

of those spiders but here comes nature

that provides us with a good spider

this is a predatory mud just as small as

the spider mite by the way what maybe

two two millimeter long not more than

that brawny quickly hunting chasing the

spider mites and here you can see this

lady in action on your left hand side

just pierces such the body fluids on the

left-hand side of the test might and

after five minutes

you see just typical dead corpse

shriveled sucked out their ports of the

spider mine and thanks to it to satiated

individuals of predatory minds a mother

on the left hand side a young lives on

the right hand side by the way a meal

for them for 24 hours are about five

individuals of the spider mites of the

bed mites and or 15 to 20 eggs of the

pest mites by the way they are hungry

always and there is another example 80s

by the way springtime now in Israel when

temperature rises sharply you can see

those red ones those aphids all over the

plants in your hibiscus in your Montana

the young fresh foliage of the spring

flush so cold by the way with a fees you

have only females like Amazon’s females

give you brystol females if you rise to

other females no bells at all

parthenogenesis was so cold and they are

very happy with that the parents here

you can see the damage because ages

secrete some sticky sugary liquid called

honeydew and this just flops the upper

part of the plant you see typical

cucumber leaf that turned actually from

green to black because it’s a black

fungus mold which is covering it

and here comes the salvation through

this parasitic wasp here we’re not

talking about the predator here we are

talking about a parasite not a

two-legged parasite but an eight-legged

parasite oh yeah this is a parasitic

wasps again two metres long slender and

very quick and it sharp

flyer and here you can see this parasite

in action like in an acrobatic maneuver

she stands visa fee in front of the

victim on the right hand side then

his abdomen and inserting a single egg a

single egg into the body fluids of the

18th by the way the ethic tries to

escape

chee-chee-chee kicks and brights and

secretes different liquids but nothing

will happen

in fact only the egg of the parasitoid

will be inserted into the body fluids of

the Enfield and after a few days depends

on temperature the egg will hatch and

the larvae of this parasite will eat the

a seed from the inside and after and

this is all natural

this is all natural this is mummies mu

mm why this is the visual result of a

dead egg filled you come to see inside

in fact a developing parasitoid that

after a few minutes you see half way out

the breath is almost complete you can

see by the way the food movies etc and

then it takes just a few minutes and if

this is a female she will immediately

mate with the male and off she goes

because time is very short this female

can be only three to four days and she

needs to give rise to around 400 eggs

that means she has 400 bad egg leads to

put her eggs into the body fluids that

is of course not the end of it there is

a whole wealth of other natural enemies

that this is just the last example again

we’ll start first with the test the

thrips what way all these weird names I

bother you with the last night of

okay just a popular names but this is a

nice slather very bad best if you can

see this sweet peppers this is not just

an exotic ornamental sweet pepper this

is a sweet pepper which is not

consumable because it is suffering from

a viral disease transmitted by those

three petals and you’ve got the natural

enemy my roots pirate bug my root

because it is rather small yeah you can

see the adult leg and two young ones and

again in action this adult pierces the

trips sucking it within just several

minutes just going to the other prey

continuing all over the place if we

spread those mighty private parts the

good ones for example in a sweet pepper

plot they go to the flowers and look

this flower is flooded with predatory

birds with the good ones after wiping

out the bad ones

that’s ribs so this is a very positive

situation by the way know how to be

developing fruit no heart to the fruit

set everything is just fine under these

circumstances but again the question is

superior Sultan what I want to want base

is a the best the natural remedy what we

do is actually this in the Northeast

Israel in kibbutz there now there is a

facility that mass-produces those

natural enemies in other words what we

do there we amplify we amplify the

natural control or the biological

control phenomenon in 30,000 square

meters of state-of-the-art greenhouses

there we are mass producing those

predatory mites those mighty pirate bugs

those parasitic wasps etc etc in many

different parts by the way they have a

very nice landscape sweety Jordanian

mountains on one hand and they D total

Valley on the other hand and a good

mild winter and a nice hot supper which

is an excellent

conditioned to mass-produce those

creatures hey by the way mass production

it is not genetic manipulation there are

no here of genetically modified

organisms whatsoever take them from

nature and the only thing that we do we

give them the optimal conditions under

the greenhouses or in the climate rules

in order to proliferate multiplied every

produce and that’s what we get in fact

you see under a microscope you see on

the upper left corner you see the single

predatory mite and this is the whole

bunch of predatory mites you see this

Apple you see this one I had one gram of

those predatory mites what grams

eighteen thousand individuals eighty

thousand individuals are good enough to

control one acre four thousand square

meters of his strawberry plot again

spider mites for the whole season

of almost one year and we can produce

from this believe you me several dozens

of kilograms on an annual basis so this

is what I’d call amplification of the

phenomenon and no we do not disrupt the

balance on the contrary because we bring

it to agricultural plot work the balance

or what’s already disrupted by the

Capitol’s here we talk with those

natural enemies in order to reverse a

little bit the wheel and to bring more

natural balance to the agricultural plot

by reducing those standards that’s the

whole idea then what is the impact in

this table we can actually see what is

an impact of a successful biological

control by good bugs for example in

Israel where we employed more than 1000

hectares 5,000 dunams

the Israeli terms of biological pest

control eat sweet pepper under

protection

75% of the pesticides were actually

reduced and Israeli strawberries even

wore 80% of the pesticide especially

those aid against

pest mites in strawberries so the impact

is very strong there was the question

especially if you ask the rowers

agriculturists why biological control

why good bugs by the way the number of

answers you get equals to the number of

people you ask but if we go for example

to this place southeast Israel they are

very about the Great Rift Valley where

the really top-notch control of the

Israeli agriculture is located

especially other greenhouse conditions

or other screenhouse conditions if you

drive all the way to a lot you see this

you see the because of the desert and if

you zoom in you can definitely watch

this bread Paris with her grandchildren

distribute the battle enemies the good

works instead of wearing special clothes

and gas mask and apply chemicals so

safety with respect to the application

this is not one answer that we get from

growers why biological control number

two many growers are infected petrified

from the idea of resistance that the

tests will become resistant to the

chemicals just in our case the bacteria

become resistant to antibiotics it’s the

same and it can happen very quickly

fortunately is the biological control or

interventional control the resistance is

extremely rare it hardly happens because

this is evolution this is the natural

issue

unlike resistance which happens in the

case of chemicals and thirdly public

demand public demand the more the public

the public demands reduction of

chemicals for growers

become aware of the fact they should

wherever they can and wherever possible

to replace the chemical control with

even here there is another grower you

see very interested in the birds the

dead ones in the good

wearing this magnifier already on her

head just walking safely in her prob

finally I were to get to activate to my

vision or in fact my dream because you

see this is their reality have a look at

the gap if we take the overall turnover

of the fire control industry worldwide

is 250 billion dollars and look at the

overall pesticide industry in all the

crops throughout the world

I think it’s times 100 or something like

that 25 billion so there’s a huge gap to

bridge so actually how can we do it how

can we bridge or that’s a narrow this

graph this gap in the course of the

years first of all we need to find more

robust good and reliable biological

solutions more robust that we can either

mass-produce or actually observed in the

field secondly to create even more

intensive and straight public demand to

reductive temples in every cultural

fresh produce and thirdly also to

increase awareness by the growers to the

potential of this industry and this gap

really narrows step by step with us

there so I think my last slide is all we

are saying we can actually see it give

nature a chance so I’m saying it on

behalf of all the biocontrol

practitioners and into matter

in Israel and abroad really did major a

chance
