Where are all the pests this year?

Not sure it was that long dry spell we had but the slug and snail population has been dwindled to a handful over the plot for the last three months.
Have put pellets down as usual, but found no trails and the assorted traps all over the plot have been empty.
My neighbours have been saying the same.
Also, although I only get a small attack of blackfly on my broad beans each year, that I cure early with a water spray or soap and water mixture. This year have seen none.
My Dad, eight miles up the road always gets quite a few attacks of blackfly on his broad and runner beans over the growing season and he has very little. He also has seen almost no slugs and snails so far.
Spoke with a few friends form local allotments and they all said they have seen liitle snail/slugs so far and no blackfly at all.
One other thing that we have all noticed is a lack of cabbage white, it really has been a rare occurrence to see them flying around, when they are usually at the start of their peak this time of year.

The only worry re the slugs, is I will have a very poor mixture for my yearly nematode solution that I always put on the potato crop. Do hope there is not a big invasion next year.

.. in my veg garden. 

Yes the same here !! The Broccoli is reduced to a few stalks every time it rains, I am thinking of pulling the whole lot up out of embarrassment  at least the Kale seems to have recovered Oops better knock on wood here
marg 

I have plenty of blackfly due to the masses of ants around!

There seem to be fewer slimies on the plot, but just as many in the garden, which is shadier.

Plenty of aphids/ants/cabbage whltes everywhere 

Cabbage White's are down here but it's not surprising after a mild winter. Apparently due to lack of cold predators are more active and feed on the pupae.

I too have noticed a distinct lack of cabbage whites but saw 3 today so maybe that's a sign of a coming plague! Very little greenfly/blackfly and although my cabbages have been noshed by slugs in one raised bed, it's got chickenwire round it which means the hedgehog/s can't get in. Yes! I'm so lucky! I've got some of the spiny things living under the bags of manure on pallets.The rest of the garden has very little slug/snail damage so the hoglets are doing a fine job......unless it's just the heat and I'll get a plague of slimy things if it rains.....
Who knows. I'll just keep on doing the organic thing as much as poss and let it all balance out......
