aphids on pomegranate tree

aphids on pomegranate tree

The main morphological and biological characteristics of each pomegranate pest species and the tools available in their integrated and organic control are briefly presented. Seasonality of A. punicae and its relationship with weather factors were observed during 2015 and 2016 at the Regional Research Station, Abohar of Punjab Agricultural University. Ants hinder natural enemies, and so reducing ant numbers will improve the success of biological control. In the fall, as aphid numbers increase, biological control also increases. The study presented in this paper was, conducted from 2012 to 2013 to compare the efficiency and selectivity of neonicotinoids, (acetamiprid, imidacloprid, thiamethoxam and dinotefuran), organophosphate (malathion), and carbamate (pirimicarb) insecticides against pomegranate aphid and the associated preda-, by an average of between 70.6 and 90.7%.

The present study found that thiamethoxam is harmful to, significant reduction in their populations. When leaves curl, it signals a problem. By contrast, malathion and pirimicarb showed the highest reduction in the population with an average ranged from 67.15 to 96.57% and were classified as harmful during both seasons. The pomegranate aphid, the key pests in pomegranate orchards in Egypt. Columns headed by different letter(s), within the same treatment date, are significantly different (P ≤ 0.05) according to Duncan's Multiple Range Test (DMRT). results are along the same lines as Ananda’s (2007) results, where he stated that thiamethoxam caused the highest per-, cent reduction of aphids and had an average of an 85.9%, reduction compared to the control.

In 2010, the total area of pomegranate in Egypt was about 4238, thousand ha (76% of these areas located in Assiut Gover-, norate) and the production was around 52 thousand tonnes, (91% produced in Assiut Governorate). Camarosa. Isofemale (clonal) lines of M. persicae were generated and subsequently tested across a range of insecticides; individual genetic clones were found to contain resistance to multiple chemical classes. Use of this pesticide may result in outbreaks of these pests. : Pirimicarb. Ananda N, Kotikal YK & Balikai RA (2009) Sucking insect and mite.

The pest population reached highest level in may and june during full blossoming and it decreased in the middle of july in late blossoming period. Aphids are a widespread and persistent pest in pomegranates, and are commonly controlled using parasites or lady beetles (depending on the time of the season).

To give your tree the best chance for a long and happy life, prune them every winter to cut off dead or diseased branches. The pomegranate aphid, Aphis punicae (Passerini) (Homoptera: Aphididae) is one of the most important pests in Egypt on pomegranate trees. It also spends the winter on winter annual weeds, added Godfrey.

(3) evaluate the efficiency and selectivity effects of foliar treatment of four neonicotinoid insecticides acetamiprid, imidacloprid, thiamethoxam and dinotefuran in comparison with the commonly used malathion (organophosphate) and pirimicarb (carbamate) on sucking insect pests of cotton, and the most common insect predators, Coccinella undecimpunctata L. and Chrysoperla carnea (Stephens) under cotton field conditions. Among different cultivars of pomegranate, Bhagwa was most and Phule Arkata was least susceptible to A. punicae infestation. Nymphs and adults of wingless cotton aphids vary in color from yellow to green to nearly black. These eggs overwinter on pomegranate and in the early spring (end of March) the eggs hatch and nymphs move to the leaves and stems on the shoot tips. These results suggested that A. punicae population dynamics on pomegranate was greatly influenced by climatic variables and host nutrition and both azadirachtin and HMOs can be considered as potential weapons for controlling A. punicae as they are significantly less toxic to A. punicae predators. These insecticides significantly reduced the pomegranate aphid population by an average of between 70.6 and 90.7%.
