What You’ll Learn
A Fascinating Foe
While I ’ve battle plenty of Colony of aphids on my rosebushes with applications of soapsuds and endlessstreams of water , I knew very little about them until I did some research .
PerRodale ’s Ultimate Encyclopedia of Organic Gardening , a favorite resource of mine that isavailable on Amazon , the aphid is one of the top 10 louse pests .
An infestation begin innocently enough . A fly female scout fly around look for a “ host ” plant to supply food and a place to reproduce . Using a mouth part called a “ stylet , ” she probe a radical or foliage to see if it ’s got what she seeks . If not , she strike on . And , much like Typhoid Mary , may convey viruses from plant to plant in her hunt .
A winged female aphid samples a leaf.
Once set up , a settlement multiplies apace . All coinage procreate by asexual reproduction , and some also by intimate means . And what I ascertain most stupefying is that if a plant becomes too overcrowded and food for thought is becoming scarce , females with wings are produce by choice for the purpose of detect unexampled homes for even more insect .
The good word , per theCollege of Agriculture , Food and Environment Department of Entomology at the University of Kentucky , is that while a plant life may appear bad , aphid feeding generally will not seriously harm healthy , established trees and shrubs .
And , at least once in account , an aphid - transmitted virus made a lot of money for some lucky horticulturists .
aliveness in the Garden
InLife in the Garden , a sport take that’savailable from Amazon , author Penelope Lively William Tell of a time in the 1630swhen tulip were all the rage .
It seems that a white species of the flush would occasionally “ break , ” or bloom with red striations . The rarity and novelty of its occurrence made the cost of bulbs sailplane to the point that one was traded for a house !
What have the unique color pattern ? It took until the twenties to determine that they were the fortuitous byproduct of a computer virus transmitted by the peach - Irish potato aphid !
And if that ’s not amazing enough , here ’s more :
This tiny pestilence excretes a mellifluous , sticky kernel called honeydew melon that collects on foliage , stamp down photosynthesis and making plants vulnerable toa disease called sooty mold .
This tomfool is a favorite food of the big - headed ant , Pheidole megacephala . It lives in a symbiotic relationship with the aphid , herding it like cattle , milking it for its honeydew , and protect it from predators .
The European chickenhearted meadow ant , Lasius flavus , has similar use , farming root aphids below the soil for a steady honeydew supply , and occasional expenditure of the bugs themselves .
How could such a nuisance of a pest be so fascinating ? !
Natural Deterrents
While I admire the survival instincts of this pervasive garden insect , it ’s still a pestilence I do n’t want in my yard .
It isn’ta good pollinator , and its very presence exposes my plants to disease and damage .
So , setting aside my inner entomologist , I receive way of life to make my backyard less sympathetic to this unwelcome visitor , and stop it in its tracks when it gets a whimsey to stay .
Healthy Plants
The skillful way of life to suppress pests and disease in the garden is to start with sizeable plants or good quality seed , and to maintain them with good guardianship .

Each feeds voraciously on our pest , and the lady beetle carry on to feast on them as matured dirt ball . Borageis a favorite breeding position of the lacewing , anddill , fennel , coreopsis , andcosmosattract ladybugs .
aphid dislike dill and fennel , so you pack a powerful puncher when you set these aromatic herbs among your ornamental specimen and veg crops .
Dill attract the braconid wasp , a good dirt ball . Its larva mummifies an aphid so it can pupate and feed until it senesce and flies out .

This proficiency may not always work , as there are some coinage of aphids that feed on only one kind of plant , while other species like a diverseness .
Shelter Gardening
A good way to bottle up insects from subside on your edible plants is to placefloating row coversover crops like berry bush and vegetable .
Another is bygrowing in a greenhouse . And for an additional guard , you may introduce ladybird larvae there with little concern they ’ll fly off at maturity .
