Wasp and Scale Insects Help Control Giant Reed Wasp and Scale Insects Help Control Giant Reed. An arundo gall wasp deposits eggs into the main stem of a giant reed. (Image by USDA/ARS) The release of tiny insects to combat the invasive weed giant reed is paying off, according to a recent U.S. Department of Agriculture (USDA) study.

Sexual Reproduction Each archegonium holds one egg (in a swollen section called the venter) and the sperm enter through the channel in the narrower, tubular section (or neck). On the side of the venter opposite the neck is the foot which anchors the archegonium to the gametophyte.etting sperm to egg. Once an antheridium has matured and contains viable sperm, the sperm need to get to the eggs in archegonia. The first step for the sperm to get out of the antheridia and the second is to then travel to the archegonia and fertilize the eggs within.

Mexican Fruit Fly, Anastrepha ludens  (Loew) (Insecta: Diptera: Tephritidae) 1 The Mexican fruit fly, Anastrepha ludens (Loew), is a very serious pest of various fruits, particularly citrus and mango, in Mexico and Central America. Its natural distribution includes the Rio Grande Valley of Texas, where populations routinely attain pest status if control measures are not practiced. Mexican fruit fly infestation is not readily controlled on a small scale, such as by homeowners. Egg and larval stages inside the fruit are safe from insecticidal treatments. The adult stage is susceptible to control, usually by a short-lived bait comprised of a contact insecticide mixed with protein and carbohydrate.

Tomato hornworms in home gardens Tomato hornworms are also parasitized by a number of insects. One of the most common is a small braconid wasp, Cotesia congregatus. Larvae that hatch from wasp eggs laid on the hornworm feed on the inside of the hornworm until the wasp is ready to pupate.

Apple maggot The larva, which is the stage of this insect's life cycle that causes the actual damage to the fruit, is similar to a typical fly larva or maggot. Other worms, especially the larvae of the codling moth, that infest the insides of apples are often confused with the apple maggot.Generally speaking, however caterpillars often feed in the apple’s core while apple maggots feed on the fruit flesh.In infested fruit, the larvae are often difficult to detect due to their pale, cream colour and small body size.The maggot stage has many enemies, including several braconid wasps: Utetes canaliculatus, Diachasmimorpha mellea, and Diachasma alloeum. The adult stage lays its eggs inside the fruit.n infested fruit, the larvae are often difficult to detect due to their pale, cream colour and small body size.

Fleas of Poultry Fleas of Poultry. The sticktight flea, Echidnophaga gallinacea, is a major poultry pest in the subtropical and tropical New World. It is unique among poultry fleas in that the adults become sessile parasites and usually remain attached to the skin of the head or anus for days or weeks.

Midge Gall midge, (family Cecidomyiidae, or Itonididae), any minute, delicate insect (order Diptera) characterized by beaded, somewhat hairy antennae and few veins in the short-haired wings. The brightly coloured larvae live in leaves and flowers, usually causing the formation of tissue swellings (galls).

Gall They can be caused by various parasites, from fungi and bacteria, to insects and mites. Plant galls are often highly organized structures and because of this the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.

- Egg -- The white or pale yellow eggs of blow flies may occur in small batches or large masses. Individual eggs are about 1.5 mm long, elongate and slightly tapered toward one end. Larva -- These white to yellowish maggots have pointed heads.They develop through three instars and become 12 to 18 mm long when fully grown. Pupa -- Blow fly pupa are encased in light brown to black puparia (the tough, hardened skins of last instar larvae). Each puparium is 9 to 10 mm long and 3 to 4 mm wide.Feeding Habits -- Most blow fly larvae feed in carrion or other decaying organic matter.epending on temperature and the substrate upon which they are feeding, maggots usually complete development in 4 to 10 days. At the end of this period, larvae typically burrow in the upper centimeters of the soil and pupate for up to a week. Adult flies emerge from puparia and make their way to the soil surface.

- Flies emerge from soil in late April or. early May, feed on pollen and nectar, and. lay white eggs at bases of newly set plants. Larvae from this generation tunnel in the. roots of small plants, causing plants to. become stunted. When mature, maggots. pupate in roots or surrounding soil.

Daphnia magna Females produce haploid eggs which are fertilized by males and encased in ephippia. These cases are carried on the female's back and fall off during her next molt. Eggs enter diapause and stay in ephippia until conditions are favorable.

Popular Study Materials from Science Sc 218 When placed on a herbaceous stem, it soon has its mouthparts embedded and is withdrawing plant sap. Sometimes so much plant sap is taken that it cannot use all of it and the aphid secretes droplets of the sugar to attract ants that in turn protect and care for the aphids.

The Tomato Hornworm The Tomato Hornworm. The Tomato Hornworm and the Wasp have a very interesting symbiotic relationship. This is a Parasitic relationship, which means one organism is benefited while the other is harmed.The wasp benefits this relationship, while the Tomato Hornworm is harmed. The wasps lay their eggs inside the Hornworm where they will hatch and begin to feed on the insides of the caterpillar.When they mature, they spin cocoons on the Hornworm's back, where they will become adult wasps when they hatch.he wasp benefits this relationship, while the Tomato Hornworm is harmed.

- Eggs: The eggs are laid in chains of up to 50 or more on branches, leaves or peduncles of host plants. Most eggs of the family Coreidae (leaf-footed bugs) are golden brown and usually laid in single rows along stems or leaf midribs. Eggs also exhibit flattened round structures clearly visible at the ends which the nymphs use to exit the egg. Figure 3. Eggs of leaf-footed bug, Leptoglossus species.

- The largest percentage of these insect galls are found on plants in the rose, juniper, willow, sunflower and oak families. According to R.A. Russo (Plant Galls of the California Region, 1979), almost half of the known galls in America occur on oak trees (Quercus).

- The commonest goldenrod gall is a round gall in the middle of a stem called a ball gall, made by the Goldenrod Gall Fly, Eurosta solidaginis. In spring, the female fly lays her eggs on goldenrod stems. When the larvae hatch, they chew their way into the stems and galls start to develop. very different type of gall is made by a tiny fly called the Goldenrod Gall Midge, Rhopalomyia solidaginis. The gall is a tight cluster of small leaves at the top of a stalk that resembles a green flower and is called a bunch gall, rosette gall or flower gall.

What Are Galls? Galls serve several important purposes for the gallmaker. The developing insect or mite resides within the gall, where it is sheltered from the weather and from predators. The young insect or mite also feeds on the gall. Eventually, the mature insect or mite emerges from the gall. After the gallmaking insect or mite leaves, the gall remains behind on the host plant. Other insects, such as beetles or caterpillars, may move into the gall for shelter or to feed.

Insect and mite galls Galls are abnormal plant growths caused by various organisms (insects, mites, nematodes, fungi, bacteria, and viruses). This publication will deal with galls caused by the feeding or egg- laying activity of insects and mites. Because of their unusual forms and colors, galls often cause homeowners to become concerned.

Cause of crown gall Symptoms and effects. The illustration shows severe gall infection at the upper crown area on the roots of a peach seedling. Galls form on the crown of the plant (the point at the soil line where the main roots join the stem) and on the roots. They can also form on the main stem above soil level, or on the branches. Galls first appear as small, pale, roughened lumps of tissue. They enlarge, darken, and become convoluted.

Butterfly Questions and Answers Most butterflies lay their eggs on plants that will be eaten by the caterpillar, when it hatches. Some species lay their eggs on the tops of leafs, some on the bottom, some at the leaf axils, some on flowers, and some on stalks. Which species do which is not known in all cases.
