Using the python client for the pageview API (https://github.com/mediawiki-utilities/python-mwviews), you could do:

from mwviews.api import PageviewsClient

p = PageviewsClient()

p.article_views('en.wikipedia', ['Abacarus_hystrix','Acarus_siro','Aceria_tosichella','Acyrthosiphon_pisum','Ahasverus_advena','Anthrenus_flavipes','Aphis_craccivora','Arhopalus','Balaustium_medicagoense','Bemisia_tabaci','Brevicoryne_brassicae','Bruchus','Ceratitis_capitata','Cicadulina','Cryptolestes','Daktulosphaira_vitifoliae','Delia','Ephestia_elutella','Ephestia_kuehniella','Etiella_behrii','Frankliniella_occidentalis','Frankliniella','Henosepilachna_vigintioctopunctata','Heteronychus_arator','Lachesilla_quercus','Lasioderma_serricorne','Liposcelis_bostrychophila','Macrosiphum_euphorbiae','Marchalina_hellenica','Myzus_persicae','Naupactus','Nezara_viridula','Oligonychus_ununguis','Oryzaephilus_surinamensis','Panonychus_ulmi','Penthaleus','Pieris_rapae','Piezodorus','Plodia_interpunctella','Plutella_xylostella','Rhopalosiphon','rhopalosiphum_maidis','Rhopalosiphum_padi','Rhyzopertha_dominica','Sirex_noctilio','Sitophilus_granarius','Sitophilus_oryzae','Sitotroga_cerealella','Sminthurus_viridis','Spodoptera_exempta','Stegobium_paniceum','Tetranychus','Thrips_palmi','Thrips','Tribolium_castaneum','Tribolium_confusum','Trogoderma_granarium','Trogoderma'], start='20150501')

Some of the articles in your list don't exist on en.wikipedia (like 'Frankliniella') but for what exists this returns the views as far back as we have them.  When we're done filling up the API we'll have data back to May 2015, but right now it only goes to August.  If you need it back further, you have to parse the dumps as others have said.  I'm curious why you need the older data, it's interesting to us as we try to figure out what else to expose through the API.  Would monthly pageviews be just as good?

I attached the result of that query here in JSON format
