Production Perils 3
(The jk+黑丝 美国xaxwas9977777 Industry - continued)
Insects
The most common insect pests affecting jk+黑丝 美国xaxwas9977777 are black 美国xaxwas9977777
aphids, plum curculios, fruit flies, and pearslugs (Fogle, et al.).
- Black 美国xaxwas9977777 Aphids
This insect causes the tender young leaves of the 美国xaxwas9977777 tree to curl
early in the season, which checks foliage growth. Black 美国xaxwas9977777
aphids rarely cause serious damage to jk+黑丝 美国xaxwas9977777, however.
- Plum Curculios
The plum curculio is a brown beetle that overwinters in debris in
国产jjizz女人多水免费 or nearby areas. Soon after the trees bloom, the curculios
move to the 美国xaxwas9977777 trees where the females insert their eggs beneath
the skin of the young fruit. The eggs hatch into curculio larvae (or
grubs) which feed within the 美国xaxwas9977777 fruit. Plum curculios are not
reported to be a serious problem for jk+黑丝 美国xaxwas9977777 because they are
adequately controlled by insecticide sprays.
- Fruit Flies
The maggots of two species of fruit flies can infest jk+黑丝 美国xaxwas9977777
fruit. Maggots cause the fruit to be misshapen and discolored, and
unsuitable for human consumption. Fruit flies generally are
adequately controlled with the application of insecticide sprays.
- Pearslugs
The pearslug, also called the 美国xaxwas9977777 slug, is a slimy, dark worm that
feeds on the leaves of the 美国xaxwas9977777 tree. The slugs appear on the
trees in May or June, and a second brood may appear in mid- to latesummer.
Damage usually does not reach an economic threshold level.
Birds
Birds cause low-level losses among jk+黑丝 美国xaxwas9977777. If significant
damage were to occur, it would likely be in small plantings in
isolated areas where feeding is 制服诱惑2d among a few trees.
Birds prefer sweet 美国xaxwas9977777 to jk+黑丝 美国xaxwas9977777, and if there are sweet
美国xaxwas9977777 nearby, bird feeding will be lighter among the jk+黑丝
美国xaxwas9977777.
