Lady beetle larvae for roses & oleanders – Coccilaure images
Aphids on your roses or oleanders? Find out how lady beetle larvae can eliminate them naturally.
Read moreOrganic anti-aphid larvae for your oleanders and low-growing plants:
The aphids found on oleanders and low-growing plants are often not eaten by ladybird larvae, due to the sap ingested by the aphids. Hippodamia undecimnotata is adapted to this type of aphids (oleander aphids including the yellow aphid Aphis nerii), which it will devour with relish. The ladybirds are supplied at the larval stage, which is more effective than the adult stage: the larvae are more voracious than the adults, and stay on the plant.
Anti-aphid ladybird larvae feed on aphids at all stages of development: winged, larvae, wingless. Each larva can consume up to 60 aphids per day. Hippodamia undecimnotata is active at a temperature of 12°C, so it can be used early in the season, from March onwards.
A few recommendations before using ladybird larvae:
Allow 1 to 3 larvae per aphid colony, or 5 to 10 larvae per m2. For 10 rose bushes: 1 box of 50 larvae.
When should ladybird larvae be used?
Use ladybird larvae only when aphids are present, generally from March to July, or outside these periods for greenhouse crops; the temperature must not be below 12°C.
For which plants is the "Coccilaure" ladybird larva recommended?
The Hippodamia undecimnotata ladybird larva is particularly effective on low-growing plants, such as rose bushes, hibiscus, but also on bean, broad bean, melon crops... the main advantage of this larva is its voracious appetite for the oleander aphid, which for other ladybird strains is not very tasty because of the sap ingested by this aphid.
How many ladybird larvae do I need?
It all depends on the aphid infestation. Generally, one box of 50 ladybird larvae is used for 5 to 10 rose bushes (allow 2 to 6 larvae per aphid colony).
How can I see if it’s working?
Ladybird larvae are as effective as the chemical treatments available on the market. To observe the results of your natural treatment, after 2 to 5 days you will notice dead, dried-up aphids, and the presence of larval molts: your larvae grow very quickly and gradually turn into adult ladybirds (in 15 days). The adults’ life expectancy is then 3 to 4 months.

Les larves sont des organismes vivants et le transport peut les fragiliser, surtout par forte chaleur. À la réception, certaines larves peuvent sembler peu actives. Placez-les rapidement sur les plantes à l'ombre et observez dans l'heure qui suit. Si la majorité est morte à l'ouverture, contactez le service client Maluttebio.
Comptez 1 à 3 larves par colonie de pucerons. Pour 5 à 10 rosiers avec une infestation modérée, une boîte de 50 larves est généralement suffisante. Pour 3 lauriers roses ou 2 à 6 m² de plantes basses, la boîte de 30 larves convient.
Les causes les plus fréquentes sont la présence de fourmis sur la plante (qui chassent les larves), un traitement chimique récent (moins de 3 semaines avant), une quantité de larves insuffisante pour l'infestation, ou une température trop basse. Vérifiez ces points avant de conclure à une inefficacité du produit.
Oui, c'est indispensable. Les fourmis "élèvent" les pucerons pour récupérer leur miellat et chassent activement les prédateurs comme les larves de coccinelle. Un traitement contre les fourmis doit être réalisé avant l'introduction des larves pour que celles-ci puissent agir.
En conditions favorables (présence de pucerons, température au-dessus de 12°C, absence de fourmis), les premiers résultats sont visibles en 2 à 5 jours. Les larves se transforment en adultes en environ 15 jours.
