you could identify weevil damage by masticate - off and damaged leaves or deflate and wilted flowers . However , the actual degree of infestation is difficult to settle without canvass the soil .
This clause include ways to name and differentiate vine from rose weevils , ways to control the attack , and ways to foreclose repeated cycles .
Vine Weevils

Rose Weevils
rosiness weevils or curculios are flightless beetle mintage that feed mostly on roses . The adult have a red , grueling out organic structure with an elongate disastrous brain that features a long and clear-cut honker promise a rostrum . They have long , black stage and mensurate about1/4of an inch when fully grown .
The lily-white oval ballock quantity 1/25 of an inch and can be difficult to spot because of their size . They stay well hidden in the buds of flowers .
The snowy , plump , legless larvae have a brown head capsule and trenchant consistence segments . Once the eggs come down into the ground , they develop and cause the most potential damage by feeding on the root system .
What Are The Signs Of Weevil Infestation?
Larvae Cause The Most Damage
Weevil larva , also referred to asgrubsor billbugs , develop below the ground when eggs descend , depositing into the soil .
They feed on root matter and can totally cut off nutrient and pee assimilation , weakening and eventually killing the plant .
Once the larvae consume the primary root structures close to the plant base , damage accelerates and becomes more marked . Depending on the weevil species , they can produce as many as 200 to 500 eggs per cycle .
full-grown vine or prove weevil mainly cause folio and flower damage and create aesthetic but minimal effects since they feed on external structures that are less important to the plant life ’s overall wellness .
Why Is It Important To Know The Life Cycle Of Weevils?
Being lettered about the life cycle of weevils can help you discover infestation during its early stage , apply treatment as require , and prevent an attempt on a larger scale .
weevil usually commence laying eggs as early as June and as of late as August after the adult females have already consumed enough solid food to aid replication . These eggs appear white and turn into a chocolate-brown chromaticity before they hatch .
The eggs typically take about two to three hebdomad to dream up , and then the larvae tunnel under the grime to feast on their horde ’s stem scheme . During summer , these white-hot and plump larvae will spend the season underground up until late fall , when they enter the pre - pupal stage .
