Effect of some protective procedures in integrated pest management against the surveyed land snails species to avoid using of pesticides in orange orchard at Tanta district, Gharbiya Governorate

الملخص EN

During 2015 and 2016 land snail species were surveyed in orange orchard and some procedure protective, hand collection, service tree operation and distance setting attractive baited traps applied to late or reduce and avoid the chemical control against land snails in Tanta district Gharbiya Governorate.

Eobania vermiculata, Monacha cartusiana and Theba pisanawere a dominant species on orange orchard and E.

vermiculata recorded the highest density then T.

pisana and M.

cartusinna.

Through spring E.

vermiculata and T.

pisana recorded the highest density and the lowest densities were in autumn, whereas density of M.

cartusinna was highly through summer and recorded the lowest density in winter.

Controlling this species by using setting attractive traps each 5 trees was more efficiency against three species, the population reductions were 55%, 51.3% and 48.9% to E.

vermiculata, T.

pisana and M.

cartusinna than hand collection and service tree operation, (31.2% and 11.3%), (33% and 14.6%) and (29.7% and 13.4%) to each species, respectively.

With applying their protective procedure consecutively the population reduced to 74.2%, 69.4 and 72 compared with using molluscicides metaldehyde bait 2% (73.2, 76.4 and 73.4 to each species respectively).

So that can use this protective procedure consecutively through year as integrate pest management program against E.

vermiculata, M.

cartusiana and T.

pisana with avoiding the chemical control in orange orchard trees.
