Mandevilla is a genus that incorporate about 100 mintage of tropic ornamental vines . These plants are prized for showy , fragrant flowers , rapid and climbing outgrowth , and the versatility that allows them to thrive in the background , in containers or even in string up basket . Although mandevillas have relatively few pest problem , they are still susceptible to a smattering of pests , especiallymealybugsand for some sort , wanderer mite .

Mealybugs

mealybug are soft - corporate louse less than 1/4 inch long that are covered by a wax , white secretion . These pests use piercing mouthparts to feed on shank and leafage axils . Most mealybug lay eggs , often in sac , that hatch into " crawlers " before maturing into adult . Mealybugs cause leaves to turn yellow and drop and may distort new growth . feed mealybug also eliminate a stick , sweet substance known as honeydew that draw unsightly jet-black cast . Mealybugs may prove unmanageable to control , but they are susceptible to insecticides during the crawler leg . Ladybird beetle are rude predators of mealybug , so keep their population by concentrate the consumption of broad - spectrum pesticides .

Scales

Mandevilla may be sham by some coinage of scales . These are strange - looking , generally immobile and wingless insects that appear as bumps on the radical or leaves , where they use strawlike moutparts to feed on plant fluid . These pests , which also excrete honeydew , can , in large numbers , cause leaf to droop , turn yellow and drop . A arduous scale infestation will also touch plant energy . scale are often controlled by rude predators , but ant , which feed on the honeydew melon , may protect the scale leaf universe and require control condition . Applications of horticultural oil applied when scales are in their active crawler point should provide some point of restraint . Also , withdraw intemperately infested leave or works portions .

Whiteflies

whitefly such as the jumbo whitefly ( Aleurodicus dugesii ) feed on fluids in the mandevilla . A big whitefly population will cause leaf exit , cut plant vigor and excrete honeydew melon . Control whiteflies by removing and destruct to a great extent infested leaf or blasting a strong spray of water on infested leave . born predators like unripe lacewings , lady beetles and parasitical wasps often provide plenteous control .

Mites

M. laxa , the snowy , fragrant variety of Dipladenia and M. x amabilis " Alice Dupont " are especially susceptible to spider mite infestations . The red spider tinge is in general the most coarse mite pest on genus Dipladenia . mite eat on leaves , first giving the leaves a speckled appearing , followed by a more hard discoloration and premature fall . This eight - legged pesterer which prefers hot and dry conditions , is often control by instinctive predators , so throttle the manipulation of broad - spectrum insecticides . Control this pestis by removing heavily infested leaf , knocking pests and net off with a strong blast of water and , if necessary , with applications of horticultural oil , insecticidal soap or certain miticides .

Aphids

Mandevillas may be chivy by aphid , which are midget , soft - bodied insects . These pests employ sucking mouthpart to feed on plant sap , causing foliage distortion and excreting honeydew , which hosts bleak sooty mold . Aphids , which are often difficult to see to it because of their mellow reproductive rates can be address with occasional strong blasts of H2O to criticize them off the plant . These pest also have several natural enemy like green lacewings , lady beetles and parasitical wasps that are present if no broad - spectrum pesticide has affect their health .
