Perhaps you should try some spelling variations:
values increased » cases increased (Expand Search), also increased (Expand Search), rate increased (Expand Search)
larvae decrease » larger decrease (Expand Search), largest decrease (Expand Search)
i larvae » _ larval (Expand Search)
_ larger » _ large (Expand Search), _ largest (Expand Search)
i values » _ values (Expand Search)
a large » _ large (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( i larvae decrease ) OR ( ((a large) OR (_ larger)) decrease ))) OR ( i values increased ))~".
• Adding a wildcard symbol may retrieve word variants: (((( i larvae decrease ) OR ( ((a large) OR (_ larger)) decrease ))) OR ( i values increased ))*.
