An example of divergent species is the apple maggot fly.

The term "railroad worm" is also sometimes applied to the Apple maggot.

The larvae is laid by a mother/female apple maggot (a fly of some sort).

Given free rein, apple maggots damage almost every fruit beyond offering even one good bite.

Ah, but the apple maggot has its Achilles' heel.

It is a parasitoid of Rhagoletis pomonella, the apple maggot.

These traps have been effective for the control of several insects including yellow jackets, aphids and apple maggots.

This flying insect can cause fruit to drop early in the season and, like the apple maggot, will sting almost all fruits on a tree.

The apple maggot fly once infested the fruit of a native Australian hawthorn.

But what we are really concerned with is the three apple maggots, as well as some other fruit-feeding insects."

Apple maggots are fly larvae that tunnel into developing fruit, making it disgusting and inedible.

Apple maggot flies are easily tricked, however.

It is morphologically very similar to another apple maggot parasitoid, Diachasma alloeum.

Use sticky red balls that resemble apples for control of apple maggots on apple and plum trees.

Codling moths and apple maggots are two other pests which affect apple trees.

The three major insect pests are apple maggot, codling moth and plum curculio.

Another trap used for fruit trees simulates a red apple and draws egg-laying apple maggots.

Since premature fruit drop is a classic symptom of apple maggot infestation, let's assume that's what your problem is.

Apple maggots are the worst, dimpling fruits and riddling them with brown trails of burrowing larvae.

Generally speaking, however caterpillars often feed in the apple's core while apple maggots feed on the fruit flesh.

The apple maggot (Rhagoletis pomonella), also known as railroad worm, is a pest of several fruits, mainly apples.

Ms. Halsey referred to her textbook: "If a total of five apple maggots are caught, then you should apply a crop protectant."

To battle apple maggot, prevent buildup of pupae in the soil by regularly removing and disposing of the fallen apples.

The blueberry maggot is closely related to the apple maggot, R. pomonella, a fruit fly in the same genus.

Some of them (called railroad worms) also have such an organ in front, which can produce a red light.

The term "railroad worm" is also sometimes applied to the Apple maggot.

One species, the railroad worm features two colors.

The apple maggot (Rhagoletis pomonella), also known as railroad worm, is a pest of several fruits, mainly apples.

In particular, many unrelated insect larvae are called "worms", such as the railroad worm, woodworm, glowworm, bloodworm, inchworm, mealworm, silkworm, Wooly bear worm.

A railroad worm is a larva or larviform female adult of a beetle of the genus Phrixothrix in the family Phengodidae, characterized by the possession of two different colors of bioluminescence.

Males may be luminescent, but females and larvae have a series of luminescent organs on trunk segments which emit yellow or green light, and sometimes an additional head organ which emits red light, as in railroad worms.

The apple maggot (Rhagoletis pomonella), also known as railroad worm, is a pest of several fruits, mainly apples.

The emergence of the apple race of Rhagoletis pomonella also appears to have driven formation of new races among its parasites.

One example of evolution at work is the case of the hawthorn fly, Rhagoletis pomonella, which appears to be undergoing sympatric speciation.

Diachasma alloeum wasps attacking Rhagoletis pomonella in apples appear to be undergoing a speciation event in concert with their hosts.

'Rhagoletis pomonella' is significant evolutionarily in that the race of this species that feeds on apples spontaneously emerged from the Crataegus feeding race in the 1800 - 1850 CE time frame after apples were introduced into North America.

Assortative mating most easily occurs if mating is linked to niche preference, as occurs in the apple maggot Rhagoletis pomonella where individual flies from different races use volatile odors to discriminate between hawthorn and apple and look for mates on natal fruit.
